the incisive edge not furnished with teeth; armed upon the anterior margin 
with a stout tubercle ; secondary or moveable plate wanting. Maxillipeds 
with large squamiform processes attached to the third and fourth joints, 
First pair of gnathopoda not subchelate. The second pair subchelate, 
imperfectly developed, long, and membranous, Ischium and carpus long. 
Dactylos rudimentary. Coxe of the gnathopoda and the two anterior pairs 
of pereiopoda deeper than their respective segments of the pereion; those of 
the second pair of pereiopoda produced inferiorly and posteriorly. Coxe of 
the fourth pair much shorter than the third.  Pereiopoda subequal. 
Posterior pair of pleopoda double-branched. Telson single, er

Animal not much compressed, smoothly ae a dorsal sinus in the 
fourth segment of the pleon. Eyes reniform. Superior antenne having 
the first joint of the peduncle reaching scarcely beyond the ocular process 
of the cephalon, the second and third joints very short; the flagellum not 
longer than the peduncle. Inferior antenns three times as long as the 
superior, the peduncle not extending beyond the peduncle of the superior 
flagellum. First pair of gnathopoda having the propodos nearly three 
times as long as the carpus, and armed upon the under side with a strong 
curved spine near the base of the dactylos. Second pair of gnathopoda 
having the propodos a little shorter than the carpus, and both inferiorly 
covered with minute denticles ; the propodos furnished upon the superior 
margin with tufts of long hair, serrated on both margins; palm short, 
inferior angle produced into a tubercle ; dactylos not so long as the palm. 
Coxe of the second pair of pereiopoda having the lower half of the posterior 
margin greatly produced. Posterior pair of pleopoda having the rami much 
longer than the basal articulation.

This species was originally described from Tasmania, where it was 
obtained by Sir J. C. Ross. Its length is stated at 1 inch, but none of the 
specimens examined by me exceeded *8 inch.
