fourth about twice as long as wide, about as long as second 
and third; fifth about one-fourth longer than fourth; flagellum 
multiculate, thirty-four articles. First antenne extend to end 
of peduncle of second antenne; the latter extend to end of fifth 
thoracic segment. Maxilliped composed of seven articles; the 
last four very plumose; third is provided with two hoops or 
blunt spines. Mandible carries a palp of three articles and a 
toothed molar. Frontal lamina, distinct, short and broad, 
anterior margin triangulate though not sharply so. 
First segment of thorax large, twice as long as third and 
fourth segments. Succeeding segments almost equal in length, 
though second is very slightly longer than third and fourth. 
Epimera are very distinct on all but first segment. Last four 
are produced at post-lateral angles especially the sixth and 
seventh. A carina is apparent on all the epimera, longitudinal 
in the first two and oblique in the last four. First three legs 
prehensile, remaining ambulatory. On propodus of first there 
are three prominent spines; one on the carpus; on the merus 
seven prominent blunt spines and about three sharp ones; 
ischium has one blunt spine like those of the merus, also a large 
spine on the outer distal margin. Second leg has three or four 
spines on the propodus; three on the carpus; eleven blunt 
spines on the merus and two spines on outer distal margin; 
ischium has two blunt spines, one large and two small ones on 
outer distal margin. Ambulatory legs provided with many 
robust spines. 
Abdomen in the specimen described shows only three seg- 
ments, four or five may be visible, however, but first is usually 
concealed. Sixth broad at proximal end, attenuated poster- 
iorly; apex rounded, provided with many strong spines, twelve 
to twenty-two. Inner branch of uropoda as long as terminal 
abdominal segment; broad at distal end where it is armed with 
spines. Outer branch is shorter than inner and narrower; also 
armed with spines on distal end and outer margin. Peduncle 
of uropoda produced to two-thirds length of inner ramus. First 
and second pleopoda of male provided with many compound 
hairs; second has a long stylet.
