NO. 3563 EUPHILOMEDES AROSTRATA—KORNICKER 5 
one with long hairs, proximal to middle. Medial surface with six 
short bristles and spines proximal to middle. Exopodite reaches about 
middle of first endopodite joint; tip with point; two terminal bristles 
of about equal length, both with short hairs, but slightly longer hairs 
on proximal bristle. Endopodite: distoventral corner of first joint 
with one short, bare bristle and three long bristles with wreaths of 
long hairs. Second joint: dorsal margin with ten bristles; two long 
and two short proximal to middle; six at about middle, one of latter 
much shorter than rest. Ventral margin with five bristles: two 
bristles distal to middle; three bristles at distal corner, clawlike, with 
sharp secondary spines. End joint with two claws of about equal 
length and about three bare bristles. Medial surfaces of basale and 
second endopodite joint provided with hairs. 
Maxilla (figs. 3a, 3, K): Dorsal margins of precoxale and coxale 
with thin, transparent epipodial appendages fringed with long, fine 
hairs. Coxale with short, bare bristle on distal, dorsal margin. 
Basale: distal dorsal margin with long, stout bristle with wreaths of 
long hairs; distal ventral margin with shorter bristle with hairs; 
narrow, elongate lobe with terminal bristle with base on distal medial 
margin near posteroventral corner, terminal bristle reaching end of 
endopodite; base of exopodite on distal lateral margin. Exopodite 
bears three bristles: proximal short, bare; two terminal bristles extend 
past end of endopodite, one with long, other with short hairs distally. 
Endopodite: first joint elongate, with clusters of stiff hairs along 
anterior margin and medial surface; distal anterior margin bears long 
bristle with wreaths of long hairs; distal lateral margin bears three (?) 
bristles with short hairs. End joint with numerous bristles, all with 
secondary hairs or spines, some clawlike. Precoxale bears three 
endites: first with about nine bristles; second about seven; third about 
nine plus one short proximal bristle. 
Fifth limb (figs. 4a—c): First exopodite joint: middle, distal, anterior 
margin with two bristles, both bear long hairs; distal, medial corner 
with short, bare bristle; triangular process in front of main tooth 
extends almost to tip of tooth. Main tooth composed of four con- 
stituent teeth: distal tooth, large, bifurcate; following tooth slender, 
with four secondary teeth; next tooth slender, with about nine sec- 
ondary teeth; fourth tooth small, without secondary teeth. Bristle 
with hairs, proximal to fourth tooth. Second exopodite joint has large 
curved tooth with small marginal teeth on inner curvature, small 
spine near distal lateral corner. 
Sixth limb (fig. 4p): Protopodite: first endite with long bristle bear- 
ing long, stiff hairs and two short bristles with fine hairs; second endite 
with one proximal and three distal bristles; third endite with eight 
distal bristles, all except shortest bristle bear stiff hairs, fourth endite
