    rostellum not visible. Keck absent, segmentation beginning immedi- ately back of the head, the proglottids rapidly becoming distinct; segments vary in length from 56 jjl to 0.75 mm.? and are always much broader than long, measuring in some cases 13 mm. broad; the poste- rior flap projects but a short distance over the anterior border of the next following segment. Genital pores double and opposite iu poste- rior half of lateral margin. Genital cloaca quite deep. Anlagen of genital canals and female glands visible in the first segments, testicles appear a little later. Male organs: Testicles appear about the thir- tieth segment, between 100 and 150 in number to a proglottid, scat- tered through the median field between the ovaries; cirrus-pouch, 0.5 mm. long by 0.17 mm. broad, very muscular, with vesicula seminalis in proximal portion and coiled smooth penis in distal portion. Female organs: Female glands nearly 1 mm. from the lateral border of the segment, some distance from the longitudinal canals; ovarian tubules appear about the thirty-fifth segment, reach their highest development from the forty-seventh to fifty-seventh segments and then rapidly atro- phy, disappearing almost entirely by the sixtieth segment; vagina ventral of the cirrus-pouch on both sides of the segment; uterus single, transverse, proximal to testicles, and possesses proximal and distal blind pouches, similar to those of Cittotcenia pectinata. Ova, 48 to 60 p ; bulb of pyriform body, 23 p. Excretory system: Dorsal canal between ventral canal and nerve. Longitudinal nerves rather close to lateral margin, near distal end of cirrus-pouch. Genital canals cross the longitudinal canals and nerve dorsally. Host.—Marmot (Arctomys marmota) by Frolich and Blanchard. Types.—Original type (?). Typical specimens with R.
