has a peduncle of five articles; the first three are small; fourth about 
as long as first three; fifth longer and narrower than fourth; flagel- 
lum composed of twenty-two articles; in five specimens examined the 
number of articles varied from twenty-two to twenty-nine, average 
twenty-four. Antennule has a peduncle of three articles; first two 
small and subequal; third half as wide and equal in length to the 
first two; flagellum composed of twelve articles, average out of five 
specimens examined, ten articles; maxillipeds composed of seven 
articles; last five provided with many long plumose spines; third 
article has two blunt hooks. Mandible robust, broad and strong 
distally where it ends in a tridentate margin. Mandibular palp has 
three articles. Frontal lamina short and broad and is sub-trian- 
gulate at the distal end. 
First segment of thorax longer than the following three, which 
are subequal. Last three longer than the three preceding. [Epimera 
distinct on all but first segment. Last four segments marked with 
an oblique, first two with a longitudinal carina. Epimera of last 
three, especially of last two, segments produced at post-lateral 
angles. First three legs prehensile, last four ambulatory. In the 
first pair the propodus has three spines on the inner margin which 
increase in size toward the distal end, where one long slender spine 
also occurs; on the outer distal end there are one or two slender 
spines. The carpus usually has but one long spine; the merus has 
five or six thick, blunt spines on the inner margin and two or three 
sharp ones. On the outer distal end there are two long slender 
spines; the ischium has one blunt spine on the inner distal margin 
similar to the blunt spines on the merus; there is one long, stout one 
and one long, slender spine on the outer distal end. The propodus 
of the second and third legs has on the inner margin four spines 
increasing in length toward the distal end. The carpus has three 
blunt spines on the inner distal end. The merus has eight or nine 
large spines on the inner margin; one long and strong and from one 
to four shorter ones on the outer distal end. The ischium has two 
very blunt spines at the inner distal end, and two or three smaller 
spines at the outer distal extremity. Last four legs provided with 
many stout spines. 
Abdomen composed of six visible segments. Last, triangular, 
gradually narrows to a rounded apex which is provided with about 
eight teeth and numerous long hairs. Peduncle of uropod is pro-
