salient angles posteriorly (fig. 2, a.). The dorsal lip (fig. 2) 
has a transverse diameter of about 0°47 mm., and carries a 
pair of double papillee at the ends of two bluntly rounded 
outer lobes of the pulp. In each ventro-lateral lip these two 
outer lobes of the pulp are unequal, the lateral lobe being 
considerably longer than the ventral lobe. The latter carries 
a large double papilla, while that of the former is small and 
simple. The neck is wider than the head. The cesophagus 
is very short (about 4 mm.), somewhat club-shaped, with a 
maximum thickness near the posterior end of 0-7 mm. It is 
muscular throughout and has no bulb or ventriculus. There 
are no intestinal or oesophageal ceca. The nerve-ring is 
situated at 1-1'15 mm. from the anterior end. The tail in

both sexes is bluntly rounded, and carries a small terminal 
spike. 
In the male the caudal end is curled ventrally in the usual 
manner. The tail is extremely short (0°15 mm.). The 
spicules are equal and short, measuring 1°25 mm. in length. 
Owing to the fact that only one male is available, it has not 
been found possible to obtain a ventral view of the caudal 
end, but, as far as can be made out, there are nine pairs of 
postanal papille, of which six pairs are subventral and lie 
close together in the short space between the cloaca and the 
tail-spike ; two pairs are laterally situated at about the level 
of the cloaca, and of these the anterior is considerebly larger
