third length of long bristles, two extremely short. Endopodite with 
two joints (fig. 5d): basal joint with a long stout bristle with wreath of 
hairs and a short, bare annulated bristle (additional bristles normally 
present on this joint in subfamily were not observed); distal joint 
elongate with stout terminal bristle with wreath of long hairs near 
middle. 
Mandible (figs. 5i, 7): Coxal endite large, bifurcate, with rows of 
spines. Basale: ventral margin of left appendage with four short 
bristles followed by one long bristle near distal end; right appendage 
with two additional bristles near middle (fig. 57), one with base on 
medial side, other on lateral side; dorsal margin of both appendages 
with three bristles, one near middle and two at distal corner; medial 
surface with one bristle at middle near ventral margin and four 
shorter bristles near proximoventral corner; short spines and long 
hairs on ventral margin near proximal end. Exopodite short with 
two bristles and hairy process at tip, inner bristle with short marginal 
hairs. Endopodite: distal end of first joint with two long and two 
short bristles ventrally; dorsal margin of second joint with proximal 
eroup of two and distal group of about five bristles; ventral margin 
with two subdistal bristles and distally with one short, annulate 
bristle and two clawlike bristles; distal joint with two long, stout 
claws of subequal length and three bare, annulate bristles. Medial 
surface of basale and second joint of endopodite with hairs. 
Maxilla (figs. 54, 6a-c): Precoxa and coxa with marginal fringe of 
fine hair, anterior margin of coxa with one short, bare, annulate 
bristle. Basale with three distal bristles: anterior bristle with wreaths 
of long hairs, medial bristle bare, posterior bristle broken off at base of 
specimen examined. Anteroventral margin of first endopodite joint 
with annulate bristle with wreath of hairs near middle and marginal 
hairs. Terminal end of endopodite with 13 bristles (fig. 6b). Exopodite 
with two long bristles and one short bristle (fig. 5k). Three endites 
(fig. 6c): first endite with six bristles; second endite with four bristles; 
third endite with six distal bristles and one proximal bristle. 
Fifth limb (figs. 6d—f): Main tooth of first joint of exopodite com- 
prised of several constituent teeth (fig. 6d): distal tooth rectangular; 
following tooth longer, slender with few low secondary teeth; next 
tooth shorter than distal tooth, slender, pointed with few secondary 
teeth proximally; next tooth short, bare. Spine with row of secondary 
spines along dorsal margin following fourth tooth. Triangular tooth 
anterior to rectangular distal tooth low, curving upward. Distal 
margin of first joint with two centrally located bristles with wreath 
of stiff hairs near middle; lateral margin with low node, bearing short 
bristle with wreath of stiff hairs near middle (fig. 6d). Second joint 
with large tooth with low crenulations along inner curvature; two
