form triangular process behind \\hich the extremit}' of finger fits ; 

 finger very long and strong. (Palm usually transverse and with 

 rounded notch in the middle; in one specimen the hands on the 

 2 sides were quite different.) 



Gnathopods of male quite similar to those of female. 



Pereiopods of moderate length, those of posterior group being 

 rather stout and fourth and fifth being subequal, all furnished with 

 tricuspidate dactyls ; epimera of moderate size, subrectangular ; third 

 to fifth pereiopods with second joints moderately expanded, posterior 

 margin produced slightly distally. 



Uropods, 3 pairs, biramous ; first pair with moderately long ped- 

 uncle, bearing stout spines on outer margin, inner ramus slightly 

 longer than outer; second uropods shorter than first, extending 

 posteriorly about as far as first pair ; third pair of flattened form, 

 extending scarcely beyond others, peduncle short, rami with truncated 

 apices, provided with fascicles of setae on outer margin and apex 

 of outer ramus which is rather broader and longer than inner. 



Telson longer than broad divided nearly to base, lobes widely 

 dehiscent ; each lobe terminating in triangular point bearing small 

 toothlike process at base of outer margin, and accompanied by 

 toothlike spine. 



Third abdominal segment with postero-lateral corners not serrate. 



Length 7 to 8 mm. 



The species was represented by numerous specimens which were 

 rather variable. Specimens were collected at Flatts Village in sand 

 from low water to 2 fathoms, in dead coral in Castle Harbor, in 

 corallines from Bailey Bay, and in Harrington Sound. It has been 

 previously recorded from the Mediterranean and the Azores.

Eyes round, small, compound, deeply pigmented. 



First antennae longer than second, with peduncle longer than 

 flagellum, first joint rather stout, slightly tapering in form, second 

 joint very slender, longer than first; third joint short, hardly to be 

 tlistinguished from first joint of principal flagellum, which is made 

 up of about a dozen segments ; accessory flagellum as long as first 

 7 segments of principal flagellum, composed of many joints. Second 

 antennae with rather short flagellum, about as long as fourth joint 

 of peduncle, made up of 8 segments; gland cone prominent, ex- 

 tending nearly to end of third joint of peduncle ; fourth joint slightly 

 longer than fifth, and like the fifth provided with long setae.
