Inner seta on coxa of legs 1-3 long and plumose, but in leg 4 very 
short (8y) and naked. Row of hairs present on inner margin of basis 
in all 4 legs. In leg 1 spinules along proximal margins of outer spines 
of exopod more prominent than those on distal margins. Endopod 
of leg 4 shorter than exopod. First segment 49 x 34y (including 
terminal spinous processes) bearing a distal inner barbed spine 32yu 
long instead of a seta. Second segment 75y x 29u (including processes) 
bearing 2 terminal unequal barbed spines 29» (outer) and 51y (inner). 
Both segments with outer margins haired, and second segment with 
short hairs along proximal inner margin and a row of minute spinules 
near insertions of terminal spines. 
Leg 5 (fig. 20) with free segment elongated and slightly arcuate, 
120u x 36y in greatest dimensions, but wider proximally than distally; 
outer convex surface covered with pointed scales (fig. 21); bearing 2 
terminal naked setae 42u and 65y in length. Naked seta on body 
near free segment 52y, with a group of spinules near its insertion. 
Leg 6 probably represented by the 2 spiniform elements near areas 
of attachment of each egg sac (see fig. 3). 
Color in life in transmitted light slightly opaque, eye red, ovary 
and egg sacs gray. 
Maur.—Body (fig. 22) resembling in general form that of female. 
Length 0.73 mm (0.69-0.75 mm) and greatest width 0.32 mm (0.29- 
0.33 mm), based on 10 specimens. Ratio of length to width of prosome 
eo? 1. 
Segment of leg 5 (fig. 23) 41u x 72y. Genital segment about as long 
as wide, 169y x 160y, in dorsal view with its lateral borders rounded. 
No intersegmental sclerite ventrally between these 2 segments. Four 
postgenital segments 22y x 52yu, 21y x 48y, 14u x 45y, and 33y x 48y 
respectively. 
Caudal ramus (fig. 23) relatively slightly longer than in female, 
24 x 22u when measured dorsally, 274 x 22u when measured ventrally. 
Innermost terminal seta with row of hairlike spinules along both 
margins proximally.
