teasing these nodules a nematode was found. It was not 
possible to secure complete specimens of the worms, owing to 
the narrow winding tracts. The head end and the bursa 
of the male were, however, secured, including a specimen 
showing the whole length of the spicules. 
The cuticle is finely striated throughout the length of the 
body at intervals of 0:°002 mm. The outline of the worm is 
wrinkled in appearance. The maximum diameter of the 
body is *45 mm., the body tapers very little towards the 
anterior end; posteriorly the body narrows considerably. 
Just anterior to the bursa, the diameter of the body is 
0°27 mm. 
The mouth-capsule is very small in size in comparison 
with the breadth of the worm at the same level. Its opening 
locks dorsally and is practically rounded in outline. It is 
0-075 mm. in length and 071 mm. in breadth. The diameter

of the body at the posterior margin of the mouth-capsule is 
0°26 mm. ‘Three pairs of teeth project from the ventral 
wall of the mouth-capsule near its outlet. The most lateral 
teeth are the largest and the two inner teeth are smallest. 
The latter lie close together on either side of the middle line. 
Two conical dorsal teeth, one on either side, project freely 
from the floor of the mouth-capsule. Their apices bend 
inwards towards each other. These teeth lie on either side 
of the duct of the dorsal cesophageal gland. Two additional 
teeth project from the ventral wall of the mouth-capsule 
close to its floor. 
The cavity of the mouth-capsule becomes narrower 
towards the beginning of the esophagus (figs. 1 & 2). 
There is no distinct esophageal funnel. The csophagus
