260 CRANGONID.E. 



This species considerably resembles the common shrimp 

 in its general aspect ; but, besides being very much smaller, 

 it differs from it in many particulars. The peduncle of 

 the internal anteunse is proportionally much shorter ; the 

 spines on the branchial region of the carapace obsolete. 

 The first pair of feet are robust, the moveable finger much 

 curved ; the second pair of feet shorter than the first and 

 third, extremely small, minutely didactyle ; the third pair 

 very slender. The abdomen is as large as the thorax for 

 rather more than half its length, and then contracts some- 

 what suddenly, by which it may be at once distinguished 

 from young individuals of the other species. There is also 

 a remarkable brown band across the fourth segment of the 

 abdomen, and a spot or two of the same colour on the 

 sides. 



Total length six-tenths of an inch.
