![broadest segments measure 5-8imn wide by 0.4-0.6mni long, and are situated about 2ri from the posterior end. The posterior segments show a decided tendency to become longer and narrower. Mature segments attain a thickness of2.2mm. 'J'iie posterior flap of the segments is broken up into fimbria*, which in the end segments attain the* length of the segment itself. There are present in each segment two lateral genital pores, two ovaries, two vitellogene glands, but only one uterus. The latter is situ- ated in the anterior portion of the median field, is composed of a small canal with numerous blind sacs, and surrounded by a thick fibrous tissue. The genital canals pass from the median field between the dorsal and ventral canals anddorsally of the nerve. The dorsal canals are somewhat smaller than the ventral canals and con- nected by transverse segmental canals. Ova measure? in diameter; horns of pyri- form body not developed. (No ova at my disposal). Typical specimens in the Bureau of Animal Industry. Specimens will be sent to museums and specialists exchanging with this Bureau. c. w. s.
