. Bulletin - United States National Museum. Science. 242 BULLETIN 120, UNITED STATES NATIONAL MUSEUM. OPALINA GIGANTEA, new species. Type.—United States National Museum Cat. No. 16605. iJost.—Biifo compactilis Wiegmann, three abundant infections, from Texas. The type infection is from United States National Museum toad No. 26460, 71 mm. long. Measurements of a large individual.—Length of body mm.; width of body mm.; thickness of body, anterior mm., middle mm., posterior mm.; diameter of nuclei mm. to mm.; diameter of endospherule mm.; cilia line in- terval, anterior mm., middle mm., posterior mm. This huge Opaliyia is shaped like a broad 0. ranarum^ but often shows clear indication of a short, rounded posterior point. It is thinnest in front and thickest behind. Its nuclei are very large, its endospherules minute and numerous, but not so numerous as those of 0. raddei. The total number of nuclei in a large individual is about 500. OPALINA ASIATICA, new species. Type.—United States National Museum Cat. No. 16608. Host.—Bufo hufo asiaticus (Steindachner), one infection from United States National Museum specimen No. 46617, 102 mm. long, from Shanghai, China, May 26, 1911; D. C. Jansen, collector. Measurements of a small individ- ual.—Length of body mm.; width of body mm.; diameter of nuclei mm. to mm.; diam- eter of endospherule mm.; , X 460 cilia line interval, anterior DiAMKTERs, SHOWING NUCLEI AND mm., posterlor mm. An ordi- A rOUTION OF THE LINES OF INSER- • T • i i • i-, -. ^^' i i TioN OF THE CILIA. uary individual is mm. long by mm. broad. This Opalina has very small nuclei and minute endospherules. In shape it approaches 0. ranarum from truncata. It seems clearly a distinct species. OPALINA [BUFOXENA], new species (?). A specimen of this form has been deposited with the United States Nation
