on one side behind the ventral sucker. In another specimen they were 
so poorly developed as to be almost non-existent. In the same 
specimen the uterus or, rather, the odtype appeared to be functioning 
imperfectly, for the eggs were badly shaped and much scattered. This 
individual further showed amphitypy and in addition the intestinal 
diverticula ended immediately behind the ovary. It was a specimen 
from Tiliqua scincoides and it was the only one in which these abnor¬ 
malities occurred. 
Family LEPODERMATIDAE. 
Genus Lepoderma Looss. 
Lepoderma nisbetii n. sp. 
(Plate XXIII, fig. 5.) 
Only, two specimens of this species were obtained from the intestine 
of a drongo (Dicrura bracteata). They were somewhat macerated but 
sufficient details remained to enable a definite description to be made. 
The worm has the typical Lepoderma shape and measures T25 mm. 
in length. The greatest breadth, across the ventral sucker, is about 
04 mm. The cuticle is closely beset with short spines which disappear 
towards the posterior end. 
The oral sucker measures 0‘22 x 0'24 mm. and the ventral sucker 
0T5 x 0T4 mm., the ratio being a little over 3:2. The ventral sucker 
is situated at a distance of 0'34 mm. from the anterior end. The 
pharynx is contiguous with the oral sucker and there is practically no 
oesophagus. The intestinal diverticula extend almost to the posterior 
end of the body. 
The genital aperture is median and lies over the intestinal bifurca¬ 
tion. The cirrus-pouch is small and does not reach much beyond the 
centre of the ventral sucker. The ovary lies O'l mm. behind the ventral 
sucker and slightly to the right side. It is a globular body with a 
diameter of 0T1 mm. The anterior testis is 0'04 mm. behind the ovary, 
from which it is separated by the uterus. It is on the left side and is 
elongated oval with a long diameter of OT mm. The posterior testis 
lies on the right side, half a diameter behind the anterior testis, and it 
is slightly larger than the latter. 
The yolk glands extend from midway between the suckers to the 
posterior end of the body. They do not unite and are of fairly uniform 
width, overlapping the intestinal diverticula along their whole length.
