End of the body rather more incurved than in the female, bluntly conical; penis forming a single spiculum, a little curved, and inclosed in a bivalved sheath, one valve being truncate and the other pointed, and reaching nearer the end of the penis than the truncate valve. Length .40 inch. Two individuals. Female.—(Fig. 03, b, magnified ten times.) Over twice as large as the male; the body short and thick; the head subacutely cofiical, with no papillpe that I can see; end of the body obtuse; extreme tip slightly mucronate. Length one inch. Two individuals. Four spec'imens, taken from ''under the eyes of Buteo Swainsonij (No. 269,) collected September 15,1872, at Snake Eiver, Wyoming Territory," by C. H. Merriam. Eustroncjiilus eJiordeiUs, n. sp. (Fig. 64, magnified ten times.) An outline figure of a worm, generically identical with IJ. hitteonis, is introduced in order to bring out more clearly the specific characters of the latter species. Two females were taken by Mr. 0. A. Walker "from the brain of the night-hawk, [Ghordeilis VirfiinianuSj) shot in June, at Campton, New Hampshire, and presented to the museum of the Peabody Academy of Science, at Salem, Massachusetts. It is a much slenderer form than E. huteonis, but much shorter and thicker than the species described and figured by Professor Wyman. Both ends of the body are much alike, the anal end being much more pointed than in E. h^ifeonis, and the anterior end of the body less tapering.
