Body not wry compact ; the anterior side plates small. 



Upper antenna reaching a little Iteytmd the p>-tl uncle of the lower; appendage 

 2-jointed, the first twice as long as the second, which has a tuft of very long setts at 

 the extremity. 



Lotftr antennae: Peduncle stout, margins of third joint produced. Mandilmlar 

 palp icith the, third joint moie than half as long as the second, narrow, pectinate. 



First gnathopods : Side plates less than half the length of the first joint, rounded 

 in front, straight behind, with a notch and a spine alxive the angle. First joint 

 rather longer than the remaining five, widening ditally ; second and third 

 joints subequal ; wrist subequal to the hand ; the hind margin of tlie hand ix x/iorf, 

 convex and prolonged in a spine-lite process, which is xlightly citnvd intnird* tn meet 

 the. point of the curved dactylus, forming a completely chclate, joint ; palm very Mitjiu',

 rounded. First joint hardly as long as the next three ; second longer and wider than 

 the third ; wrist about twice as long as the hand, which is oblong, setose on both 

 margins, palm transverse. The last three pairs of perseopod* have the first joints 

 broadly ovate, the hind margins deeply serrate, as in Podoprion, Chcvreux, and 

 Podoprionella, Sara. 



Uropod*: First and second subequal in extent and scarcely exceeding the third 

 pair; the outer minus in this pair has two subequal joints and is but little longer than 

 the inner. The telson could not be made out 



The single specimen was not dissected ; the mouth-parts therefore could not le
