The external maxillipeds are similar to those of IlaUnnis, 
though the internal distal angle of the ischium and the exter- 
nal angle of the merus are not so much produced. 
The chelipeds are very weak in both sexes, smooth, un- 
armed. The merus is short, cylindrical, and slightly con- 
stricted near the distal end. The carpus is narrow and 
rounded above. The hand is not much compressed, and nar- 
rows in the vertical direction. The fingers are nearly straight, 
very faintly toothed, more than half the length of the palm, 
nearly cylindrical, and with a proximal hiatus. 
The ambulatory legs are moderately long, with the pairs 
not differing much in length, very hairy, the joints cylindri- 
cal, the carpal joints longitudinally grooved above. The 
dactyli are acute and slightly curved. 
The male pleon is seven-segmented, the sides slightly in- 
sinuate from the third segment. The segments are medianly 
umbonate, especially at their distal margins ; the third seg- 
ment has a slight swelHng on each side ; the terminal seg- 
ment is broadly triangulate. The female pleon has the seven 
segments distinct.

This species' has the habit of covering itself with extra- 
neous materials to an excessive degree, scarcely more than the 
chelipeds and eyes are uncovered. The material consists of 
sand, calcareous matter, seaweeds, etc., very difficult of re- 
moval.

The carapace is sub-oblong, broadest near the posterior 
border, depressed — more so in the male. The surface is granu- 
late to tuberculate and nodular. The tubercles or nodules 
and the larger granules are white, many apparently formed 
by coalescence of granules : these are much more crowded near 
the posterior border. Groups have the following positions : — 
One on each hepatic region, one on each epi-branchial region, 
one on the meso-gastric, preceded in the median line bv two 
or three large single granules, one on the urogastric and two
