318 Records of the Indian Museum. [VoL. XII, 
48/xix; but these figures must not be considered as anything more 
than approximate. 
The clitellum covers xiii—ixix =6}. It is rather indefinite, 
and setae and dorsal pores are present. 
A conspicuous depression on the ventral surface, rectangular 
with rounded corners, takes up the whole length of segment xviii 
and neighbouring parts of xvii and xix; the breadth of the depres- 
sion is slightly greater than its length. Within this depression 
are two large oval cushions, touching each other in the middle line, 
and taking up nearly the whole of the depression,—but in such a 
way as to leave deep transverse hollows in front and behind, while 
laterally their margins merge into the margin of the general depres- 
sion. The apertures are anterior and internal to the middle point 
of each cushion, and hence are in front of the line of setae of the 
segment (fig. 10). In one specimen the cushions were not situated 
in a depression; in another the cushions were fused with each other 
in the middle line, and there was considerable tumidity around 
the apertures. 
The female aperture is single, and is situated on segment xiv 
between the line of the setae and the anterior limiting furrow. 
The spermathecal apertures are large, in 7/8 and 8/9, about 
one-half of the circumference apart, and opposite the tenth seta on 
each side. 
Internal Anatomy.—No septa are notably thickened; 7/8 is 
perhaps slightly so. 
There is a very rudimentary gizzard in segment vi; its walls 
are soft and not much thickened. ‘The oesophagus is rather bulged, 
and its walls have apparently a lamellate structure, in segments ix 
and x. The intestine begins in xv. 
The last heart is in xii. 
The excretory system is meganephric. 
Testes and funnels are free in segments x and xi. 
The seminal vesicle in segment xi is a single large lobed mass 
in the middle line. The second vesicle is double in segment xii, 
but the pair of which it is composed fuse together incompletely 
in xiii, and completely in xiv and xv, so that in these segments 
there is a single median vesicle only. 
The prostates are of moderate size, lobed, of the Pheretima 
type, and occupying on each side segments xviii and xix. The 
duct is stout, and beginning at the middle of the gland forms a 
loop with its convexity forwards. The duct is bound down to the 
bodywall by a number of muscular bands; its first part is the 
broadest. 
The ovaries and funnels have the usual situation. 
The spermathecae (fig. 11) present an irregularly shaped am- 
pulla with a nodular surface; its form might very roughly be called 
pyramidal. The duct is extraordinarily wide,—almost as wide as 
the ampulla; in length it is also equal to the ampulla. There is 
no diverticulum. 
There are no penial setae.
