usually longer than peduncle. Second antennae stout, character- 

 istic of male, in which sex they are sometimes subequal with 

 first pair. Short thick flagellum of few joints, often less than 

 half peduncle length. Coxal plates deeper than their segments, 

 first W'ith well extended anterior angle, this rounded narrowly. 

 Second coxal plate broad, and front angle broadly rounded. 

 First gnathopods in male stout, broad basal joint forming 

 prominent lobe at inferior angle, oblong with obliquely-convex 

 palm, and spine at rounded posterior angle. Second gnathopods 

 with broad basal joint, and with smaller and more acute inferior 

 lobe than in first pair. Rather stout hand with terminal tuft 

 of plumose setae, and oblique palm convex proximally, some- 

 what concave distally, hind angle produced. Carpus of first 

 gnathopods in female shorter than in male, hand narrower 

 though in other respects similar. Second gnathopods wnth hand 

 of female like that of male, less setose at tip, and hind end of 

 palm with strong spine. Hind angles of three front segments 

 of abdomen rounded. Terminal uropods exceed half peduncle 

 length. Color green to reddish, usually light-colored spots along 

 median dorsal line in a series, arranged as a single spot to a 

 segment. Length 20 mm. 



Remarks. — A species of wide distribution, ranging south on 

 the eastern Atlantic slope to France and the Azores, and along 

 the coast of North America south to New Jersey at least. I 

 have a single example, obtained some years ago at Point Pleas- 

 ant, by Mr. Witmer Stone. This species is found under rocks 

 and seaweed at low tide, and is also found in tubes covered with 

 sand or other matter. 



Family IPHIMEDID.^. 



Body rather robustly formed, more or less spiny, integuments 

 highly incrusted. Cephalon produced in front to a deflexed 

 rostrum, postantennal corners not projecting. Coxal plates well 

 developed, anterior pairs usually tapering to a point. Eyes dis- 

 tinct. Antennae rather slender, superior ones usually longer, 

 without any accessory appendage. Buccal area greatly project- 

 ing inferiorly, with oral parts more or less prolonged and
