antero-lateral corners. Antennular peduncle short and very stoutly built; basal 

 Joint with its outer corner produced into a process tipped with setae; second Joint 

 remarkably short; third Joint roiighly cubical in shape, as long as the other two 

 combined, with a few setae on its inner edge and inner distal corner. Antennai 

 peduncle comparatively short and more siender than the antennular peduncle; third 

 Joint slightly longer and narrower than the second; both second and third joints 

 with setae at their inner distal corners. Antennai scale about twice as long as 

 the antennai peduncle, extending for about half its length past the antennular 

 peduncle; about three times as long as broad in its widest part; outer margin 

 entire, terminating in a prominent spine; apex of scale bluntly rounded and not 

 extending beyond the terminal spine. Mandible of the usual form, but with the 

 second Joint of the palp wider than usual. First and second maxillae as in the 

 type species. First thoracic legs rather short, merus equal in length to the carpus, 

 propodus small, nail dislinct and longer than the propodus; merus and two pre-

ceding joints armed with strong plumose setae, carpus armed with simple setae 

 only, about four plumose seta on the propodus. Second thoracic legs moderately 

 siender, with the carpus equal to the merus, propodus very small, nail quite distinct 

 and longer than the propodus, a few plumose setae on the propodus, the remaining 

 joints with a few scattered simple setae. Exopods of all the thoracic limbs well 

 developod; outer distal corner of the basal Joint slightly acuminate; flagelliform 

 part of about ten joints. Telson as long as the last segment of the pleon, massive 

 and well armed, tapering slightly to a broadly rounded entire apex armed with a 

 median pair of minute spinules (which often appear as a Single spinule with a 

 bifid tip), a median pair of plumose setae arising anterodorsally to the above, and 

 two pairs of spines, rather long and siender, the inner and longer pair of which are 

 about one-sixth the length of the telson proper; lateral margins, from the level of 

 the otocysts, each with about twenty-eight to thirty spines increasing in length 

 towards the apex. Inner uropods about one and a sixth times as long as the 

 telson, with a Single spine on the inner posterior corner of the otocyst. Outer
