Wardeee Stiles. jj 6>«. the Identity of Taenia Brandti Cholodkowsky, 1894, with Taenia Giardi Monies, iSjg, and Taenia ovilla Rivolta, 1878. (Appears simultaneously in The Veterinary Magazine and in the Ceniralbl. /. Bakt. u Parasitenkunde, 1895, Vol. XVII, Erste Abt., No. 7-8, p. 254-256.) In Vol. XV, p. 552, of the C. f. B. u. P., Cholodkowsky (1894 A) described what he supposed was a new species of tape- worm, under the name T. Brandti. According to his biblio- graphical references and the text, he was evidently acquainted with the general literature on Teznia ovilla Rivolta, but he considered T. Brandti as specifically distinct from that species. A footnote shows that he was also familiar with the fact that L. G. Neumann (1892) had studied the original type specimens of T. ovilla, T. Giardi and T. aculeata Perroncito, 1882, and had asserted that they were identical. Blanchard (1894) im- mediately followed with a short note; stating that T. Brandti was identical with a cestode which I have published (1893) under the name Tlrysanosoma Giardi (Moniez, 1879). Cholod- kowsky (1894B) has quite recently again written upon his T. Brandti, changing his opinions on this species to a certain degree, but not quite to the extent warranted by the facts at hand. He now admits that his T. Brandti is identical in part with T. ovilla of Neumann, also that it is identical with my Thysanoso7na Giardi (Moniez), but he asserts that Neumann and I are in error in uniting Tcz7iia Giardi with T. ovilla, since Moniez described T. Giardi as having double genital pores, while 7. ovilla has, normally, single genital pores ; further- more, he proposes to retain the name T. Brandti. As Cholodkowsky’s quotations from my paper, and the inter- pretations he draws from them plainly show that he has been misled in his statements either because of lack of familiarity with the English language, or because he only half read my paper, the present note will perhaps be in place, in order to 218 The Veterinary Magazine. prevent further confusion regarding the species under consider- ation. I give here only the briefest possible statements cover- ing the point at issue, the details of the historical review may be found in my paper (1893). 1. Neumann (L,. G.) examined the original types of T. Giardi Moniez, and found that they agreed with the original types of T. ovilla and T. aculeata. 2. I also studied Moniez’s original specimens, both strobila and sections, and was able to confirm Neumann’s observation that the genital pores were irregularly alternate, thus agreeing with T. ovilla of which I had abundance of material. 3. I also studied some of Neumann’s material, and there can be no question that his specimens agree with the specimens I collected at Paris. 4. Moniez (the author of the species T. Giardi) has stated both to Neumann and to me, in personal correspondence, that he accepts our view that double genital pores do not represent the normal condition of T. Giardi. 5. Cholodkowsky bases his statement that T. Giardi and T. ovilla are specifically distinct entirely upon Moniez’s articles, but has never personally examined either a segment or a figure of Moniez’s original material. In view of these facts the accuracy of the statements made by Neumann and by me, which Cholodkowsky has recently called into question, but which the author of the species (Moniez) has admitted, will probably be accepted by most zoologists. The error into which Moniez was accidentally led was a most natural one and is explained in my paper referred to above ; his sections proved to be diagonal, so that they intercepted two j>ores ; taking this in connection with the occasional occurrence of double pores in T. Giardi, it is not to be wondered at that he looked upon the double-pored condition as normal. As for the quotation Cholodkowsky makes from my paper, “If it is not a T. Giardi, it must be a new species or T. Vogti ???,” and upon which he seems to lay considerable stress, he has here either misunderstood or overlooked the context. The sentence immediately preceding, ‘ ‘ Thus it is seen that this head and strobila belong to some cestode with alternate genital pores,’’ and the sentence immediately following, “The other head referred to agrees so closely with the head of M. expansa, Notes on Parasites.—Stiles. 219 that it is difficult to believe it can belong to T Giardi,” show that in the sentence referred to I was not discussing the identity of T. ovilla and T. Giardi, or the identity of the bulk of my material with T. Giardi, but was speaking of a certain head with 38 mm. strobila attached, then under discussion. To sum up, I still maintain that T. ovilla and T. Giardi are identical, and I also admit Cholodkowsky’s statement that T. Brandti is identical with Th. Giardi, as Blanchard was the first to state in print. The synonymy to date is as follows: Thysanosoma Giardi (Moniez, 1879) Stiles, 1893. 1878 Tcenia ovilla sp. n., Rivolta (nec Gmelin, 1789-90). 1879 Tcenia Giardi sp. n., Moniez. 1882 Tcenia aculeata sp. n., Perroncito. 1891 Moniezia ovilla (Rivolta, 1878) Moniez. 1891 Moniezia ovilla var. macilenta Moniez. 1893 Thysanosoma ovilla (Rivolta) Railliet. 1894 Tcenia Brandti sp. n., Cholodkowsky. Cholodkowsky’s statements in regard to the difficulty of obtaining my publication of 1893 on this species leads me to make one remark further. Leaving out of question entirely the fact that my figure of Th. Giardi in C.f. B. u. P., 1893, XIII, p. 460, must have been accessible to him, it is very surprising to me that he should have had such difficulty in obtaining an American publication as he states. Considering the fact that the Bureau of Animal Industry distributes its scientific publications gratis to those libraries and specialists who exchange publications with the Bureau, or who apply for our bulletins on given subjects, I fail to comprehend why Cholodkowsky has had such trouble. A postal card request to the Chief of the Bureau, or to me, would have been answered immediately with a copy of my paper. As a matter of fact, our Bureau of Animal Industry records show that two copies of my paper have been sent to Cholodkowsky. I regret exceedingly if, through any mistake in address, or other cause, they have never reached him. As a general principle, however, one would assume that any worker desiring the publications of the Bureau of Animal Industry would take the trouble to apply at headquarters for the particular papers desired. In conclusion I desire to add a most emphatic qualification to one of Cholodkowsky’s statements, i. e., that “bei der Charakteristik einer Species wohl die Beschreibung ihres 220 The Veterinary Magazine. Autors massgebend sein diirfte ; ” the qualification is that the author’s diagnosis, when detailed and complete, should take precedence over other diagnoses, but not over the original material. It is through ignoring this principle—one admitted by zoologists in general—that Cholodkowsky has been led into the error of redescribing a known species in face of the state- ment by Neumann that a study of the original material led to his uniting the three species T. Giardi, T. ovilla and T. aculeata. As long as we have such obliging men as Moniez and Neu- mann, to deal with in science, it would certainly have been an easy matter for Cholodkowsky to obtain original specimens from them to compare with his supposed new species. That Cholodkowsky did not know of my paper of December, 1893, is not at all surprising, as there was very little time between the appearance of our two articles.

XVII, Erste Abt., No. 7-8, pp. 256-257. It is a remarkable fact that an omnivorous animal like the hog should be so free from adult tapeworms. So far as I have been able to learn Cholodkowsky’s statement in his article 1894 A that three of his specimens of T. Brandti ( Th. Giardi) came from hogs, is the onty observation as to the presence of tapeworms in hogs ever published. In connection with Cho- lodkowsky’s statement the following two cases may be worthy of notice : Notes on Parasites.—Stiles. 221 I.—I have frequently asked butchers in this country if they have ever found tapeworms in hogs, and with one exception all have replied in the negative. This past summer I asked a butcher in lowa this question, expecting a negative answer, but received the reply that upon one occasion he had taken a single tapeworm about nine feet long from a hog ; he asserted that so far as he could judge, it was identical with the forms found in cattle and sheep. I am not inclined to accept this case as a porcine tapeworm. The slaughter-house in which the observation was made was a very small country affair, where only two or three hogs are slaughtered per week ; hogs were feeding around the grounds and received all the entrails of cattle and sheep. It seems to me more than probable that in this case, the butcher killed a hog immediately after it had eaten ovine or bovine entrails containing a tapeworm, so that the presence of the tapeworm in this hog was probably purely an accidental occurrence. The question naturally arises whether Cholodkowsky’s case is not to be explained in the same manner. Here we have a cestode found heretofore only in sheep and cattle, and now it is found in a hog in the St. Petersburg abattoir. Knowing noth- ing of the construction of this abattoir, or whether hogs would have an opportunity to feed on ovine or bovine offal, I refrain from expressing a positive opinion in regard to whether his specimens of Th. Giardi were accidentally present in hogs, or whether this cestode will really develop in swine. To explain the find as an accidental occurrence is certainly tempting, to say the least. ll.—-The second case is not so easily explained as the first case mentioned above. Meeting one of lowa’s most prominent stockraisers Dr. G. H. Grimmell, of Jefferson, I related to him my conversation with the butcher referred to. Dr. Grimmell then stated that he could add another case. Some years ago one of his hogs was sick ; he suspected worms and drenched the animal with santonine, 30 grains; aloes, 1 drachm ; Epsom salts, 3 ounces ; after a short time the hog passed a tapeworm, which, according to Dr. Grimmell’s statement, possessed four suckers on the head and double genital pores in each segment. He states that he personally saw the worm passed ; his state- ments were all confirmed by his daughter who is also a practic- ing physician. 222 The Veterinary Magazine. Dr. Grimmell added that he had several times heard of tape- worms in hogs, but never credited the reports until he saw this one. The hog had been penned and had no opportunity of swallowing ovine or bovine tapeworms. Grimmell’s statements were too exact to be disregarded, at the same time they are too indefinite to allow a decision as to what species or even genus (.Moniezia T) was found, or to explain its presence in the hog.

(Appears simultaneously in The Veterinary Magazine and in the Centralblatt f. Bakterio- logie und Parasitenkunde, 1895, Vol XVII, Erste Abt., No. 13-14, pp. 457-459. Abstract in Minutes of the Washington Biological Society for March 9 ; Science (N. Y.) p. 334, 1895.) Thysanosoma Giardi is a single-pored cestode which is of considerable interest on several accounts, more particularly be- cause, while as a rule it possesses single, irregularly alternate genital pores in its segments, it occasionally exhibits segments with double genital pores. Since finding this peculiar condi- tion of affairs and thus explaining, in part at least, the difference of opinion concerning this species between Moniez and Blan- chard on the one hand, and Neumann on the other, I have constantly been looking for some double-pored cestode which exhibited the anomaly of the occasional presence of single genital pores. Of the thousands of segments of the genus Moniezia which I have examined, I have as yet found only one with a single genital pore ; the only other anomaly of the pores in this genus worth mentioning which I have seen is the one recently reported (1894, Note 23), in which the right genital pore of one segment (M. pianissimo) opened on the dorsal surface of the segment between the two longitudinal canals, while all of the neighboring genital pores (both right and left) were perfectly normal. In Thysanosoma actinioides Diesing, 1834, which is Notes on Parasites.—Stiles. 223 also a double-pored form, I have never found any anomalies of the pores, although in this species one might possibly expect to find some segments with si ngle pores, since the uterus is single. In Ctenotcznia mar mo tee {Tania marmota Frblich, 1802, which Railliet [1893] has taken as type-species of his genus Ctenota- niai) we might also look for some segments with single pores, for here too we find only one uterus present in each segment (Stiles, 1893, P- 71, Pb VII, 7). All of the cestodes mentioned thus far belong to the sub-family Anoplocephalince of the family Taniida. In the sub-family Cystoidotceniina we also find a genus, Dipylidium (Type, D. canimini) with double genital pores, but so far as I can find no segments of this genus have as yet been recorded with single genital pores. Of the many segments of D. caninum that I have examined at different times, all have been normal. Returning now to the sub-family Anoplocephalina we find an interesting group of closely allied adult tapeworms in rabbits, pocket-gophers (Geomys), Arctomys, etc., in which the double- pored condition is characteristic for some forms, while the single-pored condition is characteristic for others. Railliet (1893) has recently taken this as a basis for classification, and has created Ctenotcenia (type-species Ct. marmota) for those having double pores, and Andrya (type-species A. peciinata [Zeder, 1800] Railliet, 1893—syn. Tania rhopalocephala Riehm, 1881) for those with single pores. In the seventy-five strobilse of rabbit cestodes of American origin which I have thus far examined, I have been able to recognize but two species. One of these possesses segments, which are broad and short (10 mm. by 0.3--0.5 mm,); double pores are present and according to the present classification ot the cestodes this species would belong in Railliet’s genus Ctenotania, although it disagrees with the type species of the genus in possessing a double uterus in each segment. In this species I found an extremely interesting anomaly in one preparation of twenty segments, which is deserving of special notice at this time, because of the recent discussion concerning the genital pores of Thysanosoma Giardi. In the first segment of the preparation (cf. figure), the pores are double, thus presenting the normal condition for this species; then comes a segment with only one pore, which is situated 224 The Veterinary Magazine. on side a ; next follow four normal, double-pored segments ; then a single-pored segment, pore on side a ; a double-pored segment; the next six segments possess single pores, all on side b; the fifteenth segment a single pore on side a ; sixteenth and seventeenth segments single pores on side b ; eighteenth, single pore on side a ; nineteenth, single pore on side b; in the last segment the pore could not be determined. I have used the de- signation “side a,” and “sideb,” as I am not yet prepared to state which side is right and which left. The entire remaining portion of the speci- men was mounted and examined, but all the segments were found to possess double pores. In the second species of adult ces- tode which I find in American rabbits, the genital pores are single and irregu- larly alternate, and the form should, according to the present classification (based upon pores alone) be placed in Railliet’s genus Andrya. The eggs, however, are arranged in packages, a condition found also in the genus Davainea R. 81. and Railliet, 1891, and in Dipylidium R. Lkt., 1863. In connection with this fact I would refer to the presence in the young stage of certain (sp. ?) rabbit tapeworms of numerous hooks on the rostellum and suckers (Stiles, 1894. Notes-31.). It will be noticed from the above that I have carefully avoided an)r attempt to determine the American forms specifically, or to make any generalizations upon the classification of this group of tapeworms. The Double-pored anoplocephaline cestode, with occasional single pores. From Lepus sylvaticus. Maryland, U. S. A. B, A. 1., No. mg. reasons are perfectly apparent; (1) The similarity of the head of the young to the head of certain species of Davainea; the Notes on Parasites.—Stiles. 225 similarity of the uterus of the last mentioned rabbit form to the uterus of Davainea and of Dipylidimn ; and the presence of a double uterus in some forms of this group (as the rabbit tapeworm first mentioned above), and of a single uterus in others (as in Ctenotcenia marmotce) bring up problems of clas- sification which can be solved only by a thorough study of the topographical anatomy of a large series of forms from different parts of the world. I have at present only about 120 strobilse from rabbits, and I am not yet willing to base any generalizations upon so small a number of specimens. (2) My second reason for shirking the specific determination is that this note is intended simply to call attention to the curious anomaly of the above double-pored cestode, an anomaly which is especially interesting at this time because of the recent dis- cussion in regard to the anomaly of the genital pores in Th. Giardi. I. 24, 1895. REFERENCES. Railliet, 1893.—Traite de Zoologie medicale et agricole, Paris. Stiles, 1892.—Notes sur les Parasites—l 3: Sur le 7tenia Giardi (Riv.) Mon.; Compt. Rend. d. 1.
