[No. 2, 
In this variable species the constant characters are :— 
(1) the discoid ( i.e ., non-globose) carapace, with elevations only 
down the middle line : 
(2) the long slender legs of the second pair. 
(3) the large size of the spine at the external angle of the buccal 
frame. 
In the Museum collection are specimens from the Sandheads, R. 
Hughli; Mergui; Andamans; and also from Hong Kong, whence the 
species was originally described by Stimpson.

Body and legs, except the hands and dactyli, closely covered with 
crisp very short velvet. 
Carapace subglobular. Rostrum short, distinctly bifid. Besides 
the spine formed by the basal antennal joint, and two denticles at the 
outer angle of the buccal frame, the antero-lateral margin is armed with 
four spines, the last of which, situated near the middle of the branchi- 
ostegal border, is considerably the largest. The carapace is traversed 
fore and aft in the middle line by a row of sharp spines, the last of 
which, situated on the posterior border, is considerably the largest. 
Between the median and lateral rows of spines, on the branchial region 
on either side, are two lavge spines, one behind the other. There are 
thus five series of spines upon the carapace, which is otherwise charac¬ 
terized by the distinct delimitation of its regions, and by a sort of fes¬ 
tooning of the border between the median and lateral series of regions. 
The clielipeds are slender throughout in both sexes, and are hardly 
equal in length to the carapace measured from the base of the rostrum 
to the base of the posterior spine: the second pair of trunk-legs are 
rather more than twice the length of the chelipeds. 
The abdomen consists of seven distinct segments in the male; and 
of four in the female, the 3rd to the 6th being fused.
