This species, as restricted by Coutiere, is closely similar to 

 5\ minus, and yet, unlike the latter, it produces large eggs and 

 advanced mysis-like larvae. It is best recognized by the obsolete 

 or small superior spine on the basicerite. Adult females are much 

 swollen. 



The rostrum and orbital spines are small, about as long as wide, 

 triangular, about equal in size, and much like those of 6". minus. 



The antennular peduncle is rather stout and long, nearly equal 

 to the carpocerite, its width to length is about as I : 5.5 ; propor- 

 tions of its three segments are about 1.8: 1.7: i. Its spine is long, 

 reaching about to the middle of the second antennular segment, 

 but not so long as in S. minus. The basicerite has a long, sharp 

 lower spine, reaching about to end of the first antennular segment ; 

 it has no sharp upper or secondary spine, but only an angular 

 prominence or denticle there, while 5*. minus has there a distinct 

 small sharp spine. 



The carpocerite is long, width to length as 1:4; it is more 

 cylindric, or less swollen, than in S. minus. It is a little longer 

 than the antennular peduncle. Its spine is about equal to the 

 latter and distinctly shorter than the carpocerite, yet a trifle longer 

 than the scale, which is rather wide. 



The lrge chela is oblong-elliptical, a little swollen in the middle, 

 and has a distal dorsal tubercle ending in a small acute spine; 

 its pollex is large and wide and the dactyl is wide and evenly arched 

 dorsally; its length is about one-half of that of the palm. The 

 width of the palm is about one-half its length. It is less swollen 

 than in 5\ mimts. 



The smaller first chela is nearly like that of 5". minus, but rather 

 more -slender. The carpus of the legs of the second pair is rather 

 slender, width to length about as i : 12 ; its length compared to 

 the merus is about as i : 0.85 ; its first article is longer than the 

 rest of the carpus. It is not so slender as in 5*. minus. The chela 

 is shorter than in the latter. The proportions of the ambulatory 

 legs are about as in 5". minus, but the merus is a little more slender, 

 width to length about as i : 4.25, and the carpus is a little longer 

 and rather more slender, while the dactyl is rather more curved
