![Host.—Black Howler (Alouatta caraya (Humboldt) [Mycetus niyer]) in Paraguay, collected by Neumeister. Types.—In collection of Leuckart; one cotype No. 1483, U.S.N.M. In the cotype of this species at my disposal the uterus is not devel- oped. The worm presents an entirely different appearance from Andrya. The muscular cirrus pouch seems to be almost wanting, so far as I can distinguish, the end of the male canal appearing simply as a widened portion of the vas deferens with very weak muscles and much less prominent than the vagina. The prostatic gland, so characteristic for Andrya rliopalocepliala and A. cuniculi, is entirely wanting. Plate IX, tigs. 4-5, give the general topographical anatomy of the segment. I do not believe that the division of the ovary into two wings as described by Meyner can be maintained, for in the cotype this division is extremely irregular. In some cases the ovary is not divided; in other segments it is divided into two, three, or four wings. I further find the dorsal canals dorsal to dorso-lateral of the longitudinal canals. BERTIA CONFERTA (Meyner, 1895), Stiles, 1896. (Plate IX, fig. 6.) 1895, Taenia (Bertia) oonferta, Meyner, Zeitsclir. f. Naturw., LXVIII (5 ser., VI), pp. 86-103, pi. 1, figs. 8-13. Diagnosis.—Bertia oonferta (Meyner, 1895), Stiles, 1896: Strobila attains 84 mm. or more in length by 6.5 mm. in breadth; serrate. Head roundish, 0.68 mm.; rostellum wanting; suckers oval. Neck about 2 mm. long, at first about as broad as the head, from which it is not sharply separated. Segments always much broader than long; sexual segments measure 5.1 mm. broad by 0.27 mm. long by 1.02 mm. thick. Genital pores irregularly alternate. Male organs: Testicles numerous in dorsal portion of median field (in figure, of transverse section con- fined to aporose two-thirds of median field at plane of genital pore), vas deferens dorso-anterior of vagina, its lateral portion quite wide; cirrus-pouch? Female organs: Glands in middle of pore side of seg- ment; receptaculum seminisoval; vagina with widened ciliated lateral portion. Uterus single, transverse, at first tubular, later with blind sacs. Ova begin to enter uterus 35 mm. from head iu about the one hundred and thirtieth segment. Three lateral longitudinal nerves as in B. mucronata. Dorsal canal dorsal of ventral canal. Genital canals pass dorsally of longitudinal canals. Calcareous bodies numerous, may attain 19 /*; 20 to 25 visible on transverse section of sexual segments, 600 to 800 on transverse section of distal segments. Host.—Bonnet Monkey (Macacus sinicus (Linnaeus) [Macacus radiatus]). Type.—In collection of Leuckart.
