Description. — Body rather slender. Eyes round, red in life. 

 First antennae slender, about long as body. Second basal seg- 

 ment longer than first, nearly twice long as third. Second 

 antennas stouter than first, especially in male, somewhat shorter. 

 Peduncle much elongated, about twice length of flagellum. First 

 five coxal plates much deeper than segments, first strong'Jy 

 produced at anterior angle and concave on superior free edge, 

 and three following plates oblong. Gnathopods in male well 

 developed, first pair unusually elongated. Carpus long and 

 narrow, propodus three or more times long as w^ide, broad 

 as and about long as carpus, short palm transverse, and large 

 dactyl projects far beyond palm when closed. Both carpus 

 and propodus with posterior edge thickly covered with rather 

 short set^e. Second gnathopods with subtriangular carpus, 

 much shorter than propodus. Latter oblong, much wider 

 than in first pair. Palm oblique, concave, posterior angle 

 prominent. Gnathopods in female comparatively small. Pro- 

 podus of first pair oblong, longer than carpus, oblique palm 

 rounded posteriorly where armed with strong spine, and dactyl 

 projects beyond palm, but not nearly so far as in male. Second 

 gnathopods with carpus produced into narrow distally setose 

 lobe, oblong hand shorter and broader than in first pair, and 

 oblique palm defined posteriorly by slight projection and strong 

 spine. ■ None of angles of abdominal segments produced pos- 

 teriorly. Terminal uropods with rami of subequal length, not 

 more than half length of peduncle. Color very variable, dark 

 reddish to light green. Length 9 mm. (Holmes.)
