cervical papilla) vary in position ; in one they are placed at the 

 junction of the two oesophageal parts, in the others up to 150 ju, 

 further back ; they may be symmetrical or asymmetrical in 

 position. The excretory pore is found about 70 fi behind the 

 cervical papillae. 



The two lateral lips are large and conical in side view, and 

 each carries two lai'ge sabmedian papillae on their outer convex 

 surface. Only two teeth are present — a large and conical outer 

 tooth with obtuse tip and slightly bent outwards, and a flattened 

 and broad inner tooth, of the same size as the outer, and having 

 its free end divided into three cusps of the same size. 



The oesophagus is straight, and forms in the female 1/5-2 to 

 1/5-4, in the male l/4'6 to 1/5-2 of the total body-length; its 

 anterior 1/1 1th or l/12th forms its muscular part, which is 

 slightly thinner than its posterior glandular portion. The nerve 

 ring encircles it in its posterior third.

The three females are 50, 38, and 36 mm. long, with a thick- 

 ness of respectively 1-9, 1-5, and 1-2 vavn. The anterior half 

 tapers considerably, but posteriorly this tapering is limited to 

 the last 4 or 5 mm. The tail is conical, and forms from 1/5 7th 

 to l/65th part of the body. Its caudal poi'es are situated in 

 slight pits in the posterior half of the tail ; their position divides 

 the tail into the ratio of 5:2. 



The vulva opens on a slight elevation, which divides the body 

 into the ratio of 1 : 2-9 ; in one of the females it is situated in 

 front of the end of the oesophagus ; this position is probably due 

 to shrinkage of the anterior part of the worm, as shown by the 

 facts that the cuticle in this region is much corrugated and that 

 the intestine immediately behind the oesophagus is thrown into 

 a loop. 



The genitalia pass straight back, and are specially characterized 

 by the absence of a common trunk portion behind the egg- 

 chamber, and by the presence of four uteri arising all together 

 from the hind end of the egg-chamber. The vagina, in the
