setides along one side. A minute setiile on proximal outer edge of 

 this segment. Maxilliped (fig. 14) 3-segmented. Two naked setae on 

 second segment. Third segment (fig. 15) bearing a naked seta, a 

 setiform element with bifurcated tip, and a terminal process about 

 22jLi long and clawlike, with a small hyaline lobe on each side of dis- 

 tal point. 



Postoral area (fig. 16) only slightly produced ventrally; an incom- 

 plete line of sclerotization between bases of maxillipeds. 



Legs 1-4 (figs. 17-20) with trimerous rami except for 2-segmented 

 endopod of leg 4. Armature of legs as follows (Roman numerals= 

 spines, Arabic nimierals= setae): 



P 1 protopod 0:1 1:0 exp 1:0 1:1 111,1,4 



P 2 protopod 0:1 1:0 



P 3 protopod 0:1 1:0 



P 4 protopod 0:1 1:0 



end 0:1 II 



Inner seta on coxa of legs 1-3 long and plumose, but in leg 4 short 

 {17 fi) and naked. In first 3 pairs of legs inner margin of basis with 

 short row of hairs, but such hairs absent in leg 4. In all 4 legs setae 

 on inner side of last segment of exopod with lateral hairs shorter prox- 

 imally than distally. Spine on last segment of endopod of leg 1 

 24ju in length. Endopod of leg 4 shorter than exopod. First segment 

 33m X 25m with inner distal plumose seta 41^ long. Second segment 

 Qlfx long (including 2 terminal spinous processes) and 23^ wide in 

 basal half and 19^ wide in distal half, the 2 halves demarcated by 

 very slight indentation. Along outer margin of both segments rows 

 of minute spinules. Terminally second segment with a row of minute 

 spinules near insertion of 2 unequal spines, both with spinulose 

 fringes, outer spine 21 fj., inner 39^ long, ratio about 1:1.86. 



Leg 5 (fig. 21) with free segment elongated and slightly arcuate in 

 outline, 66m x 23m, with short stout spines along outer edge and extend- 

 ing around to distal ventral siu"face; bearing terminally 2 naked setae 

 35m and 37m in length. Seta on body near free segment slightly 

 feathered with group of spines near its insertion. 



Leg 6 probably represented by 2 setae near areas of attachment of 

 each egg sac (see fig. 3). 



Color in life in transmitted light rather translucid, eye red. 



Male. — Body (fig. 22) resembling in general form that of female. 

 Length (excluding ramal setae) 0.89 mm (0.85-0.92 mm) and greatest 

 width 0.32 mm (0.30-0.34 mm), based on 10 specimens. Ratio of 

 length of prosome to that of urosome 1.6:1.
