Description. — Head with small rostrum and faint dorsal carina. 

 First and second antennae snbequal in length, in male little over 

 half length of body. First segment of first antennae stout, 

 laterally compressed, furnished below with a carina, which more 

 prominent near base, and second and third segments subequal. 

 Flagellum three-jointed, about long as last joint of peduncle. 

 Second antennae with flagellum three-jointed, nearly long as last 

 peduncular segment. Coxal plates broader than deep. First 

 gnathopods with carpus produced downward at postero-distal 

 angle into small lobe. Propodus oblong, narrower than carpus, 

 but about as long. Palm oblique, spinulose. Second gnathopoda 

 in male with carpus furnished at postero-inferior angle with 

 large acute tooth, above which a rounded sinus separating latter 

 from a small, rounded tooth. Propodus oblong, slightly incurved, 

 nearly long as carpus, inner edge irregular, with dactyl large and 

 stout. Second gnathopoda in female similar to first pair. Third 

 peraeopods very small, merus with long spatulate lobe on pos- 

 terior edge, carpus articulated to posterior margins of merus 

 above distal end of latter and produced greatly beyond articula- 

 tion of oblong propodus, and short and broad dactyl with an 

 abruptly recurved hook-like "tip. Terminal uropoda much like 

 preceding pair but stouter. Telson twice as broad as long, 

 distally emarginate, two lobes rounded and armed above with 

 minute hooks. Length 4.4 mm. (Holmes.) 



Remarks.— This species was originallv described from Great 

 Egg Harbor, and does not seem to have been noticed in our 

 limits since that time (1817). It lives in tubes, which it car- 

 ries about.
