Carapace discoidal, covered, as are also the legs as far only as the 
end of their merus or carpus, with a short close fur. 
Rostrum, measured from the posterior orbital border, sometimes as 
long as broad and about one-seventh the length of the carapace, some¬ 
times twice as long as broad and about one-fourth the length of the 
carapace ; deeply cleft, the spines sometimes convergent, sometimes al¬ 
most in contact throughout, sometimes slightly divergent. 
Besides a line of four teeth, situated one at the end of the basal 
antennal joint, one at the angle of the buccal frame, and one behind each 
of these, the antero-lateral margin is armed with four acute curved claw¬ 
like spines, the posterior of which is typically two-fifths to one-third the 
breadth of the carapace in length, but may sometimes be only one-eighth 
the breadth of the carapace in length ; while the three anterior are ty¬ 
pically about one-sixth the breadth of the carapace in length, but may 
sometimes be merely tubercles. 
In the middle of the posterior border is a great spine as large as the 
last spine of the antero-lateral series. 
In the middle line of the carapace is a series of tubercles and spines 
which are very variable in size : typically only two are prominent, 
and these have the form of upstanding spines, one in the gastric 
region, the other—much larger—in the cardiac region. Both of them, 
however, may be reduced to tubercles, while in front of them and also 
between them there may or may not be a line of tubercles. 
Except for this median line of elevations, the dorsum of the denuded 
carapace is either smooth, or has only a line of extremely indistinct 
elevations passing on either side obliquely from near the front towards 
the great lateral epibranchial spine. 
The chelipeds in the female are rather shorter than the carapace : 
in the male they are rather longer than the carapace, and in the adult 
male have the palms swollen. 
The 2nd pair of trunk-legs are between three and four times the 
length of the carapace measured from the base of the rostrum to the 
base of the great median posterior spine. 
The two spines on the sternum between the bases of the second 
pair of legs may be distinct or indistinct. 
The abdomen consists of seven distinct segments in both sexes.
