Iti. (EtojAagotfonia inflation, (A. Schneider), (Path. Hist., 

 1673), met along with several specimens of an unknown 

 globocephalus in the Inincn and in several tiny submucous 

 cysts in the wall of the intestine of a pig-tailed macaque, 

 Macai'iifi ni'ini'xtrlniiK (P. Z. G. Lab., 508). 



The worms, one male and four females, are colorless, 

 cylindrical on section, rigid, opa<|iie; cuticle finely striated 

 transversely. They are of nearly uniform thickness in the 

 greater part of the body length, tapering slightly an- 

 teriorly to a head about a quarter as wide as the body 

 of the worm, tapering posteriorly less rapidly to the tail. 

 Mouth terminal, circular, surrounded by a chitinous ring 

 with the cuticle over this elevated into a prominent cir- 

 cular lip. Upon the latter six rather long, pointed papilla-. 

 Posterior to this lip the cuticle of the head is expanded into 

 a collar extending for about one-third the length of the eso- 

 phagus, sharply defined posteriorly by dorsal and ventral 

 depressed transverse lines. From the level of these on each 

 side a narrow alar cuticular expansion, in which there is 

 situated a pointed papilla (opening of cervical glands). No 

 buccal cavity or capsule, the esophagus beginning immedi- 

 ately back of the mouth opening. Esophagus flask-shaped, 

 relatively short; intestine large, with thick cellular wall, the 

 columnar cells of which show especially distinctly posteriorly. 

 Anus subterminal in both sexes. The largest female meas- 

 ures 16 mm. in length and 0.45 mm. in thickness at middle. 

 Tail obtusely conical, with mucronate tip. Anus 0.2 mm. 

 from tip of tail. Vulva prominent, with thick circular lip, 

 situated 0.35 mm. anterior to anus. Double ovarian tube. 

 Ova yellowish, elliptical, with single, smooth, colorless shell, 

 and with interior often segmented; measures 0.06 to 0.08 mm.
