![Railliet1 in 1893 places Riehm’s species in liis genus Gtenotcenia. From the work of former authors and from my own observations upon the original material of T. denticulata, T. goezci, and Cittotcenia latis- sima, I propose the following as a revised specific diagnosis: Diagnosis.—Cittotcenia denticulata (Rudolphi, 1804), Stiles and Has- sall, 1890: Strobila attains 40 to 50 cm., even 80 cm.in length by 15 mm. in breadth by 3.5 mm. in thickness, is grayish to grayish red in color, and is made up of 200 or more segments. Head unarmed, 0.8 mm. broad by 0.63 mm. long, suckers large and prominent; rostellum not observed. Neck absent. Genital pores double, prominent, opposite in posterior half of margin, near corner of the segment. Male organs: Testicles 0.115 mm. in diameter, very numerous, scattered through the dorsal portion of the median field; cirrus-pouch large and prominent, 1.12 mm. long by 0.32 mm. broad. Female organs: Vagina runs ven- trally and distally of cirrus-pouch on both sides of segment; female glands very similar to those of Cittotcenia pectinata, situated close to longitudinal canals; uterus very complex. Eggs 52 to 63 y in diameter; bulb of pyriform body 16 to 24 y. Excretory system: Very complex, numerous, thin-walled longitudinal canals (probably all belongingto the ventral system); dorsal canals with thick wall. Genital canals cross the longitudinal canals and nerves dorsally. Host.—Common European wild rabbit (Lepus cuniculus). Types.—Rudolph! s type in Berlin Museum; fragments in the collec- tion of Stiles, Nos. 17,1492, U.S.N.M. Baird’s type in South Kensing- ton Museum (London); fragments in collection of Blanchard. Riehm’s cotypes in collection of Leuckart; Vienna Museum; No. 1328, XJ.S.N.M. Several typical specimens in collection of Moniez. Geographical distribution.—Europe: France (Chabert, R. Blanchard, Moniez); Saxony (Riehm). CITTOTCENIA CTENOIDES (Railliet, 1890), Stiles, 1896. (Plate XIV, figs. 1-8.) 1881, Dipylidium leuckarti, Riehm, Zeitschr. f. d. ges.
