Description. — Frontal plate rather long, in the atlult females terminating 

 in a long, distally \-cry 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 arc 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 sitle, has only three crystal cones in a 

 transverse row. — The antennulae in the female nearly as in »S'. lomjicorne; the 

 peduncle is longer than the carapace, with the two distal joints \-ery slender 

 and the third about one third as long again as the second; the ujiper flagellum is 

 slightly shorter than the lower and about as long as the peduncle; both flagella
