Description.— Frontal plate rather long, in the adult females terminating 
in a long, distally very slender rostrum, while in adult males the rostrum is very 
short or scarcely developed. The dorsal keel on the gastric area moderately 
high, anteriorly very sloping. 
The eyes are high, at least twice as high as broad (fig. 3a), somewhat pyri- 
form, with the lower section from more than half as broad again to a little less 
than twice as broad as the upper; the upper section projects much above the 
upper end of the stalk and, seen from the side, has only three crystal cones in a 
transverse row.— The antennulae in the female nearly as in S. longicorne; the 
peduncle is longer than the carapace, with the two distal joints very slender 
and the third about one third as long again as the second; the upper flagellum is 
slightly shorter than the lower and about as long as the peduncle; both flagella
