Uropod 1: peduncle and rami subequal, slender, strongly spinose 

 posteriorly; peduncle with proximal raised cluster of stout spines and 

 long setae. Uropod 2: peduncle and rami subequal, with numerous 

 slender simple setae. Uropod 3: rami slender, tapering distally; 

 outer ramus longer, terminal segment much the shorter; peduncle 

 short. Telson cleft narrowly, half way to base; lobes apically bare 

 and smoothly rounding, about 5 lateral groups of short slender spines 

 on each side. 



Female, 7-10 mm. : Similar to and slightly larger than male. Telson 

 similar but apparently with fewer lateral spines. Brood plate of 

 gnathopod 2 about as long as segment 2, margins multisetose; that of 

 peraeopod 3 short, slender, margins with 8-10 short setae. 



Remarks. — The species is very common along surf-exposed or 

 semiprotected sandy coastlines and offshore banks, ranging from the 

 southwestern shore of Cape Cod Bay, southward to Georgia and 

 northern Florida. The animal may burrow to a depth of 4 inches 

 or more in the sand near low-water level.

Description. — Male, 10.0 mm. Head broad and deep, rostrum

 plumose; segment 3 short, broad; flagellum of 9 short segments, dis- 

 tally longest, accessory flagellum of 2 slender subequal segments, 

 combined length nearly half the flagellum proper. Antenna 2:
