Pedigerous somites together about three-fourths as long as carapace, not 
differing markedly in length dorsally; first to third with pleural parts forwardly 
produced ; the third is bent backwards on the sides also, so that the sedond and 
third legs are more widely separated than are the others, 
Pleon rather robust, shorter than cephalothorax; fifth somite not longer than 
sixth, which is widened. posteriorly, where it is slightly broader than long; telson 
stout, one-fourth longer than sixth somite, laterally serrate near base, and with 
a pair of rudimentary terminal spines. 
First antenna with first and second segments. of peduncle dilated more than 
in genotype, being considerably raised on the upper face; the first is as deep as 
it is long and has a large inferior tooth; third joimt rather longer than, first: two

extended with carpus falling not far short of level of apex of pseudorostrum ; basis 
only two-fifths as long as rest of limb with a few short spines at distal end; 
propodus distinctly shorter than earpus and fully twice as long as dactylus. 
Second peraeopod slender, more than half as long as first leg, with the basis 
much shorter than rest: of limb and dentate on inner and outer edges; isehium not 
apparent; merus subequal m length to the narrow carpus, which is barely longer
