long bristles with wreaths of long hairs and short spines distally. 

 Dorsal margin with 3 bristles, 1 near middle and 2 subterminally. 

 Medial siu-face with about 5 short bristles proximally near ventral 

 corner and 1 longer bristle near ventral margin at middle of joint. 

 Exopodite reaching middle of 1st endopodite joint, with 2 subequal 

 terminal bristles with short marginal spines (fig. 3a); tip of joint with 

 blunt hirsute process bearing short spine. Endopodite: First joint 

 (fig. 2j) with 1 short spinous bristle and 3 long hirsute posterior 

 bristles distally. Second joint (fig. 2k) anterior margin with proximal 

 group of 3 bristles and distal group of 5 bristles, all bristles bare or 

 with short spines; posterior margin with 2 spinous bristles distal and 1 

 short annulated bristle and 2 clawlike bristles subterminally. End 

 joint (fig. 21) with 2 large subequal claws, 1 short anterior claw, and 3 

 annulated bristles. Medial surface of basale and 1st and 2nd joints 

 of endopodite provided with groups of hairs. 



Maxilla (fig. 3c) : Very small. It seems to have a structure typical 

 of the genus, but because of its size I have not attempted to describe 

 it fully. 



Fifth limb (figs. Sd, e) : Epipodial appendage with about 47 plumose 

 bristles. Outer lobe of 3rd exopodite joint with 2 stout plumose 

 bristles. 



Sixth limb (fig. 3/): First endite with 3 bristles, 2nd endite with 

 4 bristles, 3rd endite with 6 bristles, 4th endite with 6 bristles, 2nd 

 joint of exopodite with 14 bristles, joint not produced posteriorly; 

 epipodial appendage represented by 2 short bare bristles. Surface of 

 second joint of exopodite with clusters of short hairs. 



Seventh limb (figs. Sg, h): Cleaning bristles: 4 in distal group, each 

 with 4 or 5 bells; 3 in proximal group, each with 1 to 3 bells; surface 

 hairs not observed on bristles. Terminal comb with about 7 marginal 

 teeth, some with marginal spines. Two long curved pegs opposing 

 comb. 



Copulatory organ (figs. 3^, I) : Long, slender, divided into 3 lobes, 

 each with 2 annulated bristles; 1 lobe with large curved sclerotized tip. 



Furca (fig. 3j): Each lamella with 12 to 13 claws: primary claws 

 number 1, 2, 6, 10; secondary claws 3, 4, 5, 7, 8, 9, 11, 12, 13 (13th claw 

 not always present). Primary claws 1 and 2 separated from lamella, 

 6 and 10 joined to lamella; secondary claws all separated from lamella; 

 all claws with double row of spines. Primary claws decrease in length 

 proximally on lamella. Lamella near claws 1 and 2 with clusters of 

 long hairs. (One specimen has 13 claws on each lamella, another 

 specimen has 13 claws on the right lamella and only 12 on the left 

 lamella.)
