margins and all the angles broadly rounded, and the posterior angles, as well 
as the posterior margin of the seventh epimeron, are slightly notched and 
bristled. The upper antennse of the male are two-thirds to four-fifths as 
long as the body. The first and second joints of the pedicel are sub-equal, 
each about as long as the four basal joints of the flagellum ; the third is 
one-third as long as the second. The flagellum is about five times the 
length of the pedicel, and is composed of 30 to 35 joints, each with a few 
short hairs at tip, and all except the seven or eight basal joints and the last 
with a slender olfactory club. The secondary flagellum contains two bristled 
joints, together a little longer than the first of the primary flagellum. Ped- 
icel of lower antennse longer than that of upper, the last two joints equal, 
each a little longer than basal joints of upper antenna. Flagellum nine or 
ten jointed, without olfactory clubs. Right mandible with dental laminae 
equal, each with five conical, obtuse, sub-equal teeth. The anterior lamina 
of the left mandible is much the larger and stronger, with three very strong, 
blunt teeth : posterior lamina with three slender and acute teeth. Palpus 
three-jointed ; basal quadrate, about half as long as second, which is clavate 
and nearly twice as wide as long, with about ten long hairs on its rounded 
hind margin which are longest and closest distal ly. Last joint a little 
longer and narrower than second, regularly convex in front, straight on 
proximal half of hind margin, slightly concave on distal half, and fringed 
here with about 24 slender hairs, the three or four at tip becoming suddenly 
very much longer. A few scattered hairs on front margin of this joint. 
Inner plate of anterior maxilla is nearly hemispherical, about half as 
long as outer, with four plumose hairs on the rounded margin, which are 
about as long as the plate itself. Palpus two-jointed, first quadrate, one- 
third as long as second, which is oval, pointed, tipped with two claws and 
some smaller spines. Laminae of basal joints of maxillipeds short, neither 
pair extending beyond tips of succeeding joints. 
First two pairs of feet equal. Dactyl of first pair in male curved, two- 
thirds as long as hand . The latter is broad-ovate, two-thirds as wide as 
long, the palmar and posterior margins forming a wide angle. Long hairs 
on posterior surface in transverse rows. Palm with about fifteen short, 
notched spines, each with a hair arising from the notch Carpus sub-tri- 
angular, three-fourths as wide as propodus, hind margin very short, with 
one or two pectinate spines and a few long hairs. Second pair similar, pro- 
podus a little longer and narrower ; carpus as wide as propodus, posterior 
margin longer, with about five transverse rows of long bristles, of which the 
distal row are doubly pectinate on terminal third. The three posterior 
pairs of thoracic legs increase in size backwards, the first of these being not 
quite two-thirds as long as the last. The seventh epimeron is narrow, with 
the lower margin regularly arcuate. The tips of the first pair of anal legs 
extend beyond the tips of the second, and these beyond the tips of the third. 
The latter are therefore very short, about as long as the pedicel of the 
second pair. The outer ramus is ovate, truncate, half as long as the pedicel, 
and hairy at tip ; the inner is an unarmed rudiment, one-fourth or one- 
fifth the length of the outer. The telson of the male is a smooth cylindrical
