 gradually in the anterior third and very gradually in the posterioi 

 third of the body, and tapering abruptly behind the anus to a sharp 

 point. Anus about 200/t from tip to tail; vulva, provided with 

 prominent lips, about 250/a anterior to the anus. Eggs in uterus

Host. — Tragulus jav aniens (Javan mouse deer). 



Location. — Small intestine. 



Locality. — Calcutta Zoological Garden, Calcutta, India.

This worm in many respects resembles Bourgelatia diducta, de- 

 scribed from the intestine of pigs in Annam by Kailliet, Henry, and 

 Bauche (1919). The worms, of which only one male and one female 

 were collected, were found associated with a few specimens of 

 Llaemonchus contortus.

Figure 1 



Speci^c diagnosis. — Cystidicola: Small slender worms, cylindrical 

 for the greater part of their length, tapering at the ends. Cuticle 

 rather coarsely striated at anterior end, the striations disappearing 

 in both sexes near the level of the posterior end of the esophagus. 

 Head truncated, 80/t to 85/a in diameter, with two blunt, rounded 

 lateral lips and a pair of minute toothlike structures on the dorsal 

 and the ventral side. The mouth opening is in the form of a dorso- 

 ventral slit, the walls of the cylindrical vestibule appearing to come 

 almost together in dorsal or ventral view, but spreading out into a 

 funnel-shaped opening in lateral view. Vestibule laS/x to IGO/a long 

 and lOfx. to 12jm in diameter, with thick chitinized walls. Esophagus 

 slightly over 4 mm. long, in two parts, not sharply separated, and 

 neither distinctly muscular; anterior portion l.G to 1.7 mm. long and 

 about 52/i broad ; posterior portion 2.4 to 2.6 mm. long and about 85/* 

 broad. Nerve ring about 250/t to 350|U, from anterior end of body. 

 Excretory pore about 40/a behind nerve ring. 



Male about 9 to 11 mm. long with a maximum diameter of about 

 120/x. Testis begins at about the junction of middle and posterior 

 thirds of the body, passes forward with very slight convolution, 

 turns backward some distance behind the end of the esophagus, and 

 proceeds as a straight sperm duct to the cloaca. Cloacal aperture
