In young males the chelipeds are of proportions intermediate between those 

 of the adult male and female.

Distinguished by the vertically erect ear-like hepatic spine, the base of 

 which forms a great polished buHa on either side of the buccal frame, giving the 

 animal, when viewed front end on, a bat-hke appearance. 



The body and legs are downy, the legs being fringed with short broad 

 curly hairs. 



The carapace, in which the cardiac region is broad and prominent and not, 

 as in 8. beauchampi, narrow and sunken, has, besides the hepatic spine already 

 mentioned, the following marks : — 



On the branchial regions, below and anteriorly, a sharp sinuous human-ear- 

 shaped crest ; above and posteriorly a spine ; and near the middle hue, anteriorly, 

 an acumination. On the gastric region four faint elevations. On the cardiac 

 region, and also on the intestinal region, in the middle line, an acuminate emi- 

 nence. 



The rostrum consists of two divergent spines, about one-third the length of 

 the rest of the carapace. 



The eyes stand well out from beneath the pre-ocular spine, and are retractile 

 against a small post-ocular tooth. 



The other appendages closely resemble those of the preceding species ; but 

 the chelipeds, in the adult male, are shorter, being only equal in length to the 

 carapace and rostrum, and the fingers have their cutting edges crenulate instead 

 of smooth. 



In females and in young males the chelipeds have the same relative pro- 

 portions as in Scyramathia beauchampi.
