long as wide (2.18 x 1.30 mm). Caudal rami (fig. 30) conspicuous, 
longer than wide (.90 x .52 mm); armed with four prominent plumose 
setae and two small subterminal plumose setae, inner margins of rami 
with row of short hairs. 
First antenna (fig. 31) 2-segmented; basal segment with 26 short 
spines and setae, terminal segment with 12 short naked setae. Second 
antenna (fig. 32) stout; terminal claw with accessory process near base 
and two setae, one short and one long; appendage armed with number 
of adhesive areas as indicated in figure. First maxilla (fig. 33) with 3- 
segmented terminal ramus, basis bearing group of three short setae. 
Second maxilla (fig. 34) terminal claw with rows of fine hairs; second 
segment bearing short stout spine covered with fine spinules, patch of 
hairs on outer distal corner. Maxilliped (fig. 35) well developed; ter- 
minal claw opposed by two adhesion areas on basal segment. 
Legs 1-4 biramose. Leg 1 (fig. 36) both rami 2-segmented. Exopod 
first segment large, bearing spine on outer distal corner; second seg- 
ment with fringe of digitiform processes along outer edge and bearing 
three short spines and four setae. Endopod first segment unarmed, 
distal end produced to form broad lamella overlapping base of terminal 
segment; terminal segment with three stout setae and patch of hairs on 
outer edge. Leg 2 (fig. 37) both rami 3-segmented. Exopod first two 
segments of each with spine and seta on outer and inner distal corners 
respectively, terminal segment with two lateral spines and six setae. 
Endopod first segment with seta on inner distal corner, second seg- 
ment with two setae at inner distal corner, terminal segment with six 
setae. Leg 3 (fig. 38) both rami 3-segmented. Exopod with same arma- 
ture as leg 2. Endopod with last two segments modified as in figure 39. 
Leg 4 (fig. 40) rami 2-segmented. Exopod first segment with spines on 
outer distal corner, second segment with spine on outer and seta on 
inner distal corners, terminal segment with two spines and five setae. 
Endopod with one, two, and three setae on the inner margin of each 
segment respectively.

Leg 5 (fig. 41) represented by process on ventral surface of genital 
segment bearing one outer fringed spine and two inner plumose 
setae (see fig. 29); a fourth plumose seta internal to process. Leg 6 
(fig. 42) a process near posterior corner of genital segment bearing 
one outer naked spine and one short inner plumose seta.
