Palate well delimited from the epistome. fferent branchial 
channels well defined. 
Chelipeds in the male much more massive and much longer than 
any of the legs. 
The third pair of legs though shorter are not less massive than the 
first 2 pair, and end in a powerful talon like dactylus. The fourth 
(last) pair of legs are short and slender. 
The sternal grooves of the female do not meet; they end in tuber- 
cles on the second segment of the sternum, between the bases of the 
2nd pereiopods. 
The branchial formula and the number and disposition of the 
epipodites are exactly the same as in Dromia Rumphit.

Carapace etc. with a dense short velvety tomentum. 
Carapace pentagonal, with the posterior border of the pentagon 
curved, its dorsal surface quite flat, its greatest length (in the adult) 
about equal to its greatest breadth, its regions all well defined by 
grooves, the cervical and branchial furrows both equally well cut. 
There are sometimes a few granules near the borders of the carapace. 
Front cut into 3 teeth with granular edges, the middle tooth being 
smaller and on a much lower plane than the others. 
Upper border of orbit very oblique: a granular spine or tooth 
marks the true inner supra-orbital angle of higher Brachyura. Outer 
border of orbit apparently wanting, but on denudation a concave row of 
granules is found there. Sub-orbital lobe granular and dentiform. 
On the lateral borders of the carapace are usually two teeth, one 
immediately behind the cervical groove, the other immediately behind 
the branchial groove: one (the posterior) or both of these teeth may 
be nearly worn away, but usually they are both very distinct. Between 
the first spine and the orbital tooth is a (sometimes broken) row of 
granules, and between the same spine and the outer angle of the buccal 
cavern is a row of granular tubercles: the surface of the subhepatic 
region between these two rows of granules may, when denuded, be 
granular or not. 
The chelipeds of the adult male are, as in Petalomera, much more
