Second gnathopods wdth subrectangular epimeron about as broad 

 as long, with ventral margin provided with a few setae ; second joint 

 very stout with 2 long spines on j^roximal third of posterior margin 

 and numerous fine setae on anterior margin and 2 short stout setae

 rectangular, twice as long as broad with single seta on postero-distal 

 apex ; wrist triangular, about as broad as long ; hand stout, subrect- 

 angular, slightly broader distally than proximally, palm slightly 

 oblique, provided with setae, prehensile angle produced to form 

 curved toothlike process and provided with prehensile spine, posterior 

 margin with about 8 fascicles of setae, anterior submargin with about 

 4 fascicles ; finger of usual form, stout. 



Epimera of moderate size ; pereiopods of moderate size and pro- 

 vided with clawlike fingers. 



First 3 abdominal segments with posterior and lateral margins 

 entire and rounded. 



Uropods, 3 pairs, biramous ; rami of first 2 pairs styliform and 

 subequal, with large .spines apically ; third uropods with rami much 

 longer than peduncle and somewhat flattened, outer ramus longer 

 than inner, with rather long spines on outer margin and apex, inner 

 ramus with long spines apicall}'. Telson subrectangular, about as 

 broad as long, divided to base, each lobe with several long stout 

 spines on inner apex.

 body ; peduncle about -/s as long as flagellum which is made up 

 of nearly 20 segments ; first joint of peduncle swelling somewhat 

 in thickness at middle, about 3 times as long as broad, provided
