Remarks. — This species is easily separated from S. Thompsonii by its small eyes 

 and by its much broader antennal squama which is only about three times as long as broad, 

 while it agrees with S. Thompsonii and differs from all other species by having the endopod 

 of the uropods overreaching the exopod. This exopod has only 2 or 3 marginal spines. — 

 From most of the localities females with brood are to hand, proving that the species propagates 

 itself during the whole year. 



Distribution. — According to Dana, Sars and Ortmann this species is widely 

 distributed in the tropical Pacific, from a station between Galapagos and Acapulco to the 

 Philippine Islands and the Arafura Sea; according to Sars it has also been taken in the North 

 Pacific. The Copenhagen Museum possesses a good number of specimens taken by the Danish 

 "Galathea" Expedition at two localities, viz. lat. i9°i4'N., long. iió°6'E., and in the Bay 

 of Bengal. The species is always taken at the surface.

Description. — Body moderately slender. Frontal plate of the carapace (fig. 5^) in 

 both sexes considerably produced, triangular, with the tip narrowly rounded or subacute. Eyes 

 moderately large, black. Antennal squama subequal in both sexes (figs. 5^ and 5 c), not fully 

 three times as long as broad ; terminal lobe about half as broad again as long. Gnathopods 

 (fig. ^d) and thoracic legs (fig. 5^) moderately slender; gnathopods about three-fourths as long 

 as first pair of thoracic legs which is somewhat shorter than third pair. Male pleopods and 

 pseudobranchial rami as described in the definition of the group. 



Uropods moderately broad and subequal in both sexes (figs. 5 ƒ and 5//); exopod con- 

 spicuously overreaching the endopod, its proximal joint with 6 to 9 spines occupying less than 

 half of its outer margin, its distal joint considerably less than half as long as the proximal and 

 somewhat longer than broad, at most half as long again as broad. The telson reaches about the 

 articulation of the exopod ; it is moderately broad, distally a little broader in the female (fig. 5^)
