914 MR. G. M. VEVERS ON NEMATODA FROM MAMMALS 



median. The oesophagus consists of two parts — -a short anterior 

 portion and a longer and thicker posterior portion. 



The male is smaller than the female, its attenuated caudal 

 extremity ending in a close spiral. Preanal and postanal papillfB 

 are present. The spicules are unequal, the longer consisting of 

 two parts, the shorter dagger-shaped with an expansion at the 

 proximal end. 



The tail of the female is curved dorsally, and bears two lateral 

 apjDendages close to the caudal extremity. The vulva is near 

 the anterior end of the body. The eggs are thin-shelled. Ovo- 

 viviparous, parasitic in the peritoneal cavity of mammals. 



Type-species, PajjiUosetaria traguli, sp. n. 



Papillosetaria traguli, sp. n. 



Host. Tragulus stanleyaniis. 



Habitat. Peritoneal cavity. 



Locality. Java. 



SjKcific diagnosis. — Papillosetaria : Body tapering at both 

 extremities, more especially towards the tail. Head rounded, 

 not separated from the remainder of the body. The mouth is 

 guarded by two lips, lined by an oval ring of chitin which 

 projects very slightly beyond the mouth. The head is surrounded 

 by four papillte : two latei-al and two submedian. The body, 

 with the exception of the two extremities, is irregularly studded 

 with small cuticular bosses. 



Male. — Length 5*7 cm. ; maximum breadth 280 p. 



The anterior portion of the oesophagus measured 500 /x in 

 length, the posterior region 9'1 mm. 



The nerve ring is 200 /x, distant from tlie anterior end. 



The tail is coiled in a close spiral. 



The ano-genital opening is 120 /jl from the caudal extremity, 

 which ends in a small rounded knob. 



There a,re three pairs of postanal and four pairs of preanal 

 papili8e. 



The spicules are unequal, the larger measuring 370 /x. in length 

 and consisting of two portions — an anterior cylindrical portion 

 and a terminal twisted portion ending in a sharp point. 



The shorter spicule is 85 /x. in length, and also consists of two 

 portions — a proximal expanded portion and a distal dagger- 

 shaped portion. 



Female. — Length 14-5 cm. ; maximum breadth 460 /a. 



Anterior portion of the oesophagus is 400 /.i long, the posterior 

 portion 9'6 mm. 



The anus is '5 mm. from the caudal extremity; the tail portion 

 has a distinct curve dorsally. 



The tail ends in a bifid appendage ; near the extremity are two 

 lateral appendages. 



The vulva is 650 /x, from the head end. 



Ovoviviparous ; embryos measui-e 230 /u in length.
