 Anoplocephala; Stiles- in 1893 sei)arated the double-pored forms from 

 j\[oniezia, but did not establish any g^enus for them; Eailliet' in 1893 

 created the genus CtcnoUcnia for the double-pored forms and Aitdrya 

 for the single-pored forms. 



My studies now lead me to adopt Cittotwnia for the double-pored 

 leporine cestodes, and to divide the unarmed single-pored forms 

 between the geuera Anoplocephala, Andrya, and Bertia.

Diagnosis. — Anoplocephalina^ with segments broader than long. 

 One set each of male and female organs in each segment; genital pores 

 unilateral (dextral''); 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. (Jenital 

 canals cross the longitudinal canals and nerves dorsally. Calcareous 

 bodies (always'?) absent from parenchyma. Eggs with well-devtloped 

 pyriform body. Hosts: Perissodactyla, liodentia. 



Type.—A.perfoUata (Goeze, 1872), E. Blanchard, 1848.

^Max Braun (1894, Vermes, 36-37 Lieferung, p. 1138) erroneously gives the date of 

 this genus as 1870; R. Blanchard spells the generic name PhigoUr.nia. 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 dillerent 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. 



^\\\ A. wimerosa the pores are evidently dextral, but in the other species I am 

 unableto determine whether they are dextral or sinistral, either from the figures or 

 descriptions given by various workers. In one of my preparations of A. mamiUana 

 they are certainly sinistral; in another preparation they are apparently dextral. 

 Professor Zschokke has reexamined his preparations of A. mamiUana at my request 

 and writes mo that ho finds the; jiores dextral, which agrees with the topography 

 found upon a preparation by Railliet very recently sent to me.
