Although this is a scant infection, the few individuals found are of so distinct a sort that one does not hesitate to assign them to a distinct species. CEPEDEA MEXICANA, new species. Ty^e.—United States National Museum Cat. No. 16502. Host.—Rana pipiens Schreber, one infection, from United States National Museum specimen No. 3295, 72 mm. long, from Charco Escondino, Matamoros, Tamaulipas, Mexico, March, 1853; Couch, collector.

These Ceijedeas, after 65 years in the rectum of the preserved frog, are in fair condition for study, though internal details of structure are not well seen. The body form is shown in the figure. The nuclei are distinctly ellipsoidal, in many cases being twice as long as broad. FlO. 128. CEPBDEA MEXICANA, X 460 DIAMETERS, rm t •.! .1 • i i hey lie with their long axes in general parallel, or nearly parallel with the major axis of the body. The cilia are short. The rather slender form of the body, and especially the very small ellipsoidal nuclei are distinguishing characters of this small Cepedea. CEPEDEA FORMOSAE, new species. Type.—United States National Museum Cat. No. 16523. Host.—Bufo melanostictus Schneider, three infections; one, scant, from United States National Museum specimen No. 37511, from.
