Superior antenne shorter than inferior; middle joint of 
peduncle the longest. Inferior antenne having the peduncle 
rather longer than that of superior, last joint slightly longer 
than fourth; flagella of both antenne fringed throughout with 
unusually long and conspicuous sete. G'nathopods: both pair 
alike, hairy; hand ovate, rather shorter than wrist; finger 
small. rst and second pereiopods with metacarpus very long 
and flattened, longer than wrist and hand combined; wrist 
very short, hand double length of wrist; nail very long, slen- 
der, and acute. Third and fourth pereiopods presenting an un- 
usual appearance, from the wrist being much broader at its 
termination than the hand, which articulates with the anterior 
portion of its distal extremity, while the posterior portion is 
furnished with a bundle of stout spines; there are also three 
transverse rows of spines on the sides of the wrist; hand as 
long as wrist, but only half as broad; nail very short, stout. 
Last pereiopods with the thigh produced posteally and also 
inferiorly, but in such a way that the hinder margin is slightly 
concave; surface of thigh setose; metacarpus and wrist ex- 
panded, wide, flat, lobed at the margins and edged with spines 
and spine-like sete; hand and nail very minute, combined 
scarcely larger than an ordinary nail; hand aattierianine with
