Legs. The fore and mid legs are of the same length and cahbre, the only difference 
being that in the latter the tibia is about one-eighth broader apically and the 
claw a little longer, stouter and darker. Their chaetotaxy, too, is practically 
identical, the femur bearing 3-4 minute dorsal bristles, and 3-4 short spines 
anteriorly. The tibia with four ventral short spines towards the apex, and two 
equal sub ventral, one near the apex, and another before one-half, posteriorly; 
anteriorly there are also two spines^ that near the 
apex (almost median, not subventral) more robust, 
the median one much smaller. Mid coxa larger 
than fore coxa; hind legs (Fig. 2, C and D), claw 
short and blunt. 
Abdomen. The shght development of the sclerites in 
this region and the consequent obscuring of the 
segmentation makes it difficult to as.sign to their 
respective positions the various rows of bristles, etc. 
Of these rows there are, on the dorsal surface, about 
fifteen, arranged as follows:

The edge of the genital plate, which is posteriorly 
gently conoave with a blunt angle medianly, is frayed 
with about sixty short spine-like processes. Gonopods 
short, rounded, wide apart, with one short stout 
spine inwardly directed at the inner angle, and four 
along the edge outwardly. The tenth stemite bears 
on each lobe two minute bristles.
