    all tlie double-pored forms in Dipylidium. R. Blanchard1 in 1891 placed the double-pored forms in Moniezia, the single-pored forms in Anoplocephala; Stiles2 in 1893 separated the double-pored forms from Moniezia, but did not establish any genus for them; Railliet3 in 1893 created the genus Ctenotcenia for the double-pored forms and Andrya for the single-pored forms. My studies now lead me to adopt Cittoteenia for the double-pored leporine cestodes, and to divide the unarmed single-pored forms between the genera Anoplocephala, Andrya, and Bertia. Genus ANOPLOCEPHALA, E. Blanchard, 1848 (nee Stal 1870). 1848, Anoplocephala, E. Blanchard, Ann. des Sci. nat., 3 ser., Zool,, X, p. 344. Type by elimination, Tcenia equina perfoliata, Goeze, 1782. 1871, Plagiotcenia4 Peters, Proc. Zool. Soc. Lond , p. 146. Type, Tcenia gigantea, Peters, 1856. 1891, “Plagotcenia, Peters, 1871’’(as synonym) in R. Blanchard, M€m. Soc. zool. France, IV, p. 446. Diagnosis.—Anoplocephalime with segments broader than long. One set each of male and female organs in each segment; genital pores unilateral (dextral5); testicles in the aporose, ovary in the pore side of the median field. Uterus a transverse tube with proximal and distal pouches. Dorsal canals lie dorsal or lateral of ventral canal. Genital canals cross the longitudinal canals and nerves dorsally. Calcareous bodies (always?) absent from parenchyma. Eggs with well-developed pyriform body. Hosts: Perissodactyla, Rodentia. Type.—A. perfoliata (Goeze, 1872), E. Blanchard, 1848. 1 Sur les Helminthes des Primates Anthropoides, MAm. Soc. zool. France, IV, pp. 186-196. Notices helminthologiques: 7 —Cestodes du groupe des Anoplocephalime R. Blanchard, 1891, M6m. Soc. zool. France, IV, pp. 443-450. 2 A Revision of the Adult Cestodes of Cattle, Sheep, and Allied Animals, Bull. IV, Bur. An. Ind., U. S. Dept. Agric. ' 3Traite Zool. m6d. et agric., I. 4Max Braun (1894, Vermes, 36-37 Lieferung, p. 1138) erroneously gives the date of this genus as 1870; R. Blanchard spells the generic name Plagotcenia. A typograph- ical error in R. Blanchard, 1891, p. 446, gives Anoplocephala the date of 1868, while Braun (loc. cit., p. 1133) dates the genus 1847. Errors of this kind naturally creep into every author’s writing. In this connection I would call attention to the list of Cestoda given by Braun (loc. cit., pp. 1133-1145). While this list is extremely valua- ble in tracing the different species, it must not be looked upon as complete; further- more, care must be exercised in using the dates of species given by Braun. Rudolphi’s species of 1810 are erroneously given as 1808; Krabbe’s species of 1869 are erroneously given as 1870. A number of other species are also incorrectly dated. 5 In A. wimerosa the pores are evidently dextral, but in the other species I am unable to determine whether they are dextral or sinistral, either from the figures or descriptions given by various workers. In one of my preparations of A. mamillana they are certainly sinistral; in another preparation they are apparently dextral. Professor Zschokke has reexamined his preparations of A. mamillana at my request and writes me that he finds the pores dextral, which agrees with the topography found upon a preparation by Railliet very recently sent to me.
