The head is triangular, longer than broad. 



A small secondary eye on each side of the head, at the l)ast! of 

 the first ])air of antenn^xi. 



Tlie first pair of antennw are much shorter tliaii the pereion, the 

 flagellum is richly provided with hairs along its whole length. The se- 

 condary fiagellum is longer than the first joint of the true flagellum. 



The first segment of the pereion equals the second in length; the 

 sixth is as long as the seventh. 



The femora of the fifth, sixth, and seventh pairs i){ pereiopoda are 

 elongate-ovate, almost pear-shaped. The fifth pair are the longest, the 

 following decreasing. 



The peduncles of the pleopoda are egg-shaped. 



The first segment of the urus is twice as long as the second. 



The telson is ovate, only a little bifid. 



The only specimen of this animal that I got was ver\^ damaged, 

 being taken from the stomach of an Exocoetus. It seems to be closely 

 allied to S. ultramarina, but is distinguished from it by comparatively 

 good characteristics, as the setose flagellum of the Ih'st pair of antenn;e, 

 the form ef the femora of the last three pairs of pereiopoda, especially 

 of the last, and the form of the telson. 



The body is arched, but not as much as in S. ultramarina. 

 The head is proportionally much largei- than in the preceding 

 species, more obtuse; the excavation for the insertion of the first pair
