Notes: As far as it is possible to judge from the structure of the 

 pereopods, this species is close to S. excisa but differs from it in a longer 

 distal denticle on the 2nd segment of pereopods II, relatively greater 

 length of this segment, absence of a sharp bend in the inner margin 

 of uropods II opposite the place of attachment of the exopodite, and a 

 narrower telson. Evidently this species of Scina could be included in the 

 tullbergi group. 



Distribution: Northern tropical Atlantic between 25° and 40° N and 

 10° and 25° W Pacific Ocean — the Fiji Islands. It is found in catches 

 from 0-250 m (Pacific Ocean) and in horizontal catches from depths of 

 350 and 360 m. 



This species is absent in our collections.

Wagler, 1926: 401, 1927: 107. 



Length of sexually mature specimens up to 6 mm. 



The body and head are without keels. Antennae I are very wideset; 

 they are relatively thick and equal to the pereon in length. The mouth 

 cone is small. The protopodite of the maxillipeds is broad but very short;
