Carapace pyriform. Rostrum broad, exceedingly short—hardly 
surpassing the level of attachment of the eyes—emarginate, slightly 
deflexed. 
Eye-stalks long, recurved, retractile towards the sides of the 
carapace : a post-ocular tooth, not however affording any concealment 
to the eye. Antennulary fossse coalescent to form a single chamber. 
Antennae moderately long, almost entirely exposed to dorsal view, the 
free joints of the peduncle flattened. 
External maxillipeds with the merus narrower than the ischium, 
and giving attachment to the next joint at the summit. Chelipeds in 
both sexes slender — but most so in the female — and short. Some of 
the ambulatory legs long. 
The abdomen in both sexes has all seven joints distinct, and is 
as broad in the adult male as it is in the adult female—covering almost 
the whole sternum.
