Abbreviations: C, row of cirri; c, row of hairs; f, flange formed by fusion of hairs; H, simple spine; P, longer 
plumose spine; p, shorter plumose spine. Roman numerals indicate the numerical orders of legs or of joints, 
arabic numerals the numbers of spines and setae present on them. 
with two pairs of bosses only on anterior 
face. Cirri on outer margin of exopodite of 
last two legs more or less fused together 
forming pectinate rims. Those on first exo- 
podite joint of second legs and those at outer 
angle of protopodite of third legs cover a 
somewhat wider area. Non-plumose spines 
on exopodite of all legs with double row of 
fine pectination. . Fifth leg rudiments are 
small, oboval papillae located on side flaps of 
genital segment at about its posterior one- 
third. They are armed with a short apical 
spine and with three setae on outer border. 
Caudal rami as long as abdomen, with four 
subequal plumose spines which are inter- 
posed between two minute spinules, and with 
finely ciliated inner border. Male unknown. 
In addition to the generic characters, the 
present species is distinguished from the 
known species of Nesippus and Prosaetes by its 
trilobed genital segment. The median lobe 
probably represents the fused sixth segment, 
which is distinct in some other pandarids, for 
it is demarked from the fifth segment proper 
by an inconspicuous, anteriorly arched, sur- 
face groove.
