Second gnathopods very large ; second joint about twice as long 

 as wide at distal end, proximal end rather narrow, anterior margin 

 notched and slightly convex, anterior apex produced, forming a 

 triangular process, posterior margin rather strongly convex ; third 

 joint shorter than long; fourth joint about as long as broad, rec- 

 tangular with small process extending from distal end of posterior 

 margin ; wrist very small, articulating with anterior margin of fourth 

 joint ; hand large, suboval, anterior margin slightly convex ; palm 

 rather long and very oblique, nearly parallel with anterior margin, 

 separated from posterior margin by rather prominent process bear- 

 ing prehensile spine, palm provided with a rather deep notch near 

 distal end, behind which is a toothlike process, proximal to which 

 the palm is nearly straight and less prominent than toward the 

 distal end ; finger stout and curved, moderately long. 



Second thoracic segment provided with long acutely pointed 

 process ventral to articulation of gnathopod which is near posterior 

 end of segment. Pereiopods of third and fourth segments wanting. 

 Branchial vesicles narrow, 3 times as long as broad, present on 

 third and fourth thoracic segments. Fifth, sixth, and seventh pereio- 

 pods of usual form. 



Abdomen represented by a single segment with a single pair of 

 rudimentary uropods. 



Length about 9 mm. 



There were 2 specimens collected by Dr. L. J. Cole, July 15,

The following description is modified from Haswell's of C. inermis 

 which is evidently the same as C. danilevskii. (Proc. Linn. Soc. 

 N. S. Wales, vol. 4, p. 348. 1879.) 



Cephalon terminating anteriorl}' in minute mesial tooth. Neck 

 very long ; first segment of body longer than head and neck, other 

 segments shorter. 



First antennae as long as head and first 2 thoracic segments ; 

 flagellum shorter than last 2 segments of peduncle. Second an- 

 tennae slightly longer than peduncle of first ; flagellum shorter than 

 last 2 joints of peduncle. 



First gnathopods short with ovate hand having a longitudinal 

 palm which is undefined.
