tion present immediately posterior to maxilla, extending between 
maxillae bases. 
Female and male maxilliped (fig. 3f) 2-segmented, base situated 
lateral to maxilla base, body extending anteriorly to antenna base. 
First segment strongly developed, broad proximally, tapered distally, 
bearing single, long, finely plumose seta from knob on distal inner 
surface. Second segment short, inner surface cuplike, outer surface 
rounded; distal surface with large, sharply curved claw and finely 
plumose seta. 
Thoracic legs 1-4 biramous, fifth leg uniramous. Ramal count 3-3 
on first 4 legs. For nature of legs and armature, see figure 4 and table 2.

Discussion.—The Eniwetok specimens differ from Shiino’s original 
description (1957) in several respects: 
1. The total length is only 80 percent of that given for the holotype 
(2.28 mm for Shiino’s holotype specimen, 1.82 mm average for the 
Eniwetok specimens) although Shiino (1957, p. 416) indicates that 
the holotype is the largest specimen in his collection. Other measure- 
ments also differ although it is suggested that these differences are 
due to both the size of the holotype and the effect of natural variation. 
2. The caudal rami of the Eniwetok specimens have 3 setules on 
the outer surface while Shiino indicates only 2. The third setule, 
however, may have been overlooked as all 3 are small and almost 
transparent.
