6 PROCEEDINGS OF THE NATIONAL MUSEUM VOL, 125 
Surface of prosome and urosome with minute hairs as in female. 
Ratio of length of prosome to that of urosome 1.48:1. 
Rostral area (fig. 24) angular, with a minute median posteroventral 
knob. 
First antenna resembling that of female but with 2 aesthetes 
about 100u long added on segment 2 and another such aesthete on 
segment 4 (at points indicated by arrows in fig. 7), so that formula 
is 4, 13-+2 aesthetes, 6, 3+1 aesthete, 4+1 aesthete, 2-++1 aesthete, 
and 7-+1 aesthete. Second antenna (fig. 25) resembling that of female, 
but last segment relatively longer, 99 along outer edge, 68y along 
inner edge, and 21, wide. 
Labrum, mandible, paragnath, first maxilla, and second maxilla 
like those in female. Maxilliped (fig. 26) slender and 4-segmented 
(assuming that proximal part of claw represents fourth segment). 
First segment unornamented. Second segment bearing on medial 
surface 2 naked setae and 3 rows of spinules, a single row extending 
the length of segment, other 2 rows close together and restricted to 
region distal to setae. Third segment very small and unarmed. Claw 
slender, 185u long (measured along its axis), with narrow terminal 
lamella, slight fringe along its distal concave surface, and 2 very 
unequal setae near its base, one on postero-inner surface 864 long 
and finely barbed at its tip, other on anterior surface only 5y and 
naked. Claw showing a suggestion of division about midway. 
Area between maxillipeds and first pair of legs resembling that of 
female. 
Legs 1-4 segmented as in female and with same spine and setal 
formula, except for endopod of leg 1 (fig. 27), which has arrangement 
of 0-1; 0-1; I,I,4. This endopod geniculate, with second and third 
segments set at an angle to one another. First two segments without 
outer distal spinous processes. Third segment elongated, nearly as 
long as first two combined; with 2 terminal spines having strong 
lateral spinules; a prominent minutely spinose process near insertion 
of inner of these spines. Last segment of endopod of leg 2 (fig. 28) 
with 2 of terminal spinous processes larger than in female and bearing 
numerous minute spines. Legs 3 and 4 like those in female. 
Leg 5 (fig. 29) with elongated slender straight free segment, 33 x 9u, 
with nearly parallel sides in dorsal view, bearing a few surficial scales 
and 2 terminal elements, an outer naked seta 30u long and an inner 
spiniform seta 20u long with coarse short lateral spines. No spinules 
on body near insertion of free segment. 
Leg 6 (fig. 30) a posterolateral flap on ventral surface of genital 
segment bearing 2 naked setae 22u and 27y long.
