Length .036 to .045 mm., breadth .03 mm. Found very frequently and abundantly within the stomach of the remarkable bryozoon Urnatella gracilis. (Pr. A. N. S., vii, 191.) 12. Nyctotherus velox Leidy.

Mouth round, surrounded with a wide circular lip which is emarginate below. Male generative aperture? com- municating with a hemispherical cavity (acetabulum ?) one fourth the length of the body from the head. Length 9 lines, breadth 1$ lines. Five specimens were obtained from the fauces of the Alligator mississipiensis, in Florida, by Prof. J. W. Bailey, of West Point. Is it probably a species of Distomum, with the ventral acetabulum emersed within the body ? 16. Monostomum ornatum Leidy.

Numerous specimens were obtained by Prof. Agassiz from the intestine of Sphargus coriacea. 18.? Monostomum molle Leidy. Body depressed, elongated elliptical, posteriorly convex. Head ? mouth ? Length 9 lines, breadth 2 lines. I have found two specimens, of what I suspect to be a species of Monostomum in the lungs of two individuals of Sternotherus odoratus The species is so soft that in the removal of the specimens I mutilated both, and since then I have been unable to find others. 19. Distomum lanceolatum Mehlis. Reported to exist in the sheep, Capra aries; the ox, Bos taurus; and the hog, Sus scrofa. Stated to be frequent in the sheep, in several of the Western States. 20.
