This species also comes under B.a./3. in Hansen's key, and as regards 

 the first peraeopod might form a separate group with dagama. The 

 shape of the rostrum, however, is so different from that of any other 

 species in the genus, excepting crassimanus, and, to a lesser degree, 

 chiltoni Stebb., that it stands quite apart.

The ventral keel on the peraeou is slighter than in the 3 species 

 just described. In segments 1 and 2 in $ it is raised into a spiniform 

 forwardly directed process, in 9 only feebly raised, in segments 5-7 the 

 posterior apices are feebly dentiform in both sexes. 



The inner plate of the maxilliped was originally stated to have only 

 3 coupling-hooks ; on re-examination of the mounted specimen, how- 

 ever, I find there are 5.
