Body and appendages, except the hands and the tips of the dactyli, 
covered with an extremely dense soft fur. 
Beneath the fur the carapace is almost smooth, its surface being 
hardly broken by a median line of pimples on the gastric region ; but 
its antero-lateral border, on each side, is armed with four sharp teeth 
of about equal size —one at the angle of the buccal frame; one, which 
has sometimes a tubercle at its base, on the sub-hepatic region ; and 
two on the front part of the branchial region. The basal antennal joint 
has also the form of a tooth, and midway between it and the tooth at 
the outer angle of the buccal frame is another tooth. So that, includ¬ 
ing the pointed basal antennal joint, the antero-lateral margin of the 
carapace shows six teeth : there is no spine, though occasionally a trace 
of a tubercle, on the posterior border. 
The rostrum hardly breaks the general subcircular outline of the 
carapace: it is cleft at the tip, and, measured at the level of the base 
of the post-ocular tooth, is broader than long. 
The pterygostomian region is longitudinally grooved. The cheli- 
peds in the old male are times the length of the carapace and 
rostrum, and are enlarged, especially as to the palm, which is £ as 
broad as long, and is inflated on the inner side: the fingers also are 
stout and meet only in (about) the distal third. In the female the 
clielipeds are only about £ the length of the carapace and rostrum, and 
are throughout slenderer than the other legs. The 2nd pair of trunk- 
legs (first ambulatory legs) are from twice to 2£ times the length of the 
carapace and rostrum. 
The abdomen in both sexes consists of seven distinct segments, 
and the second segment in the female bears a large median elevation. 
A common species in muddy waters in the vicinity of the mouths 
of the large rivers of India.
