 plate with 6 setae, outer with 11 spines, 2^ Joint of palp with slender 

 spines on apex of one maxilla and stouter spines on the other, characters

 oval, widening a little distally, palm oblique, moderately defined. Gnatho- 

 pod 2, 5*^ and 6*^ joints subequal, longer and less spinöse than in gnathopod 1.

 plates, 4*^ Joint as long as 5*^ and 6*^^ combined, 5*^ very short, shorter 

 than the finger. Peraeopod 3, 2^ Joint piriform, lower bind corner not 

 produced, 4*^ longer than 5*^, b^^ than 6*^. Peraeopod 5, 2*^ Joint very 

 broad, scarcely forming a lobe below, not produced, 5*^^ Joint as in peraeo- 

 pod 4 longer than 4*** or 6*^, finger reversed. Branchial vesicles simple. 

 Uropod 3, rami about thrice as long as peduncle, not reaching beyond 

 uropod 1. Telson short, not longer than peduncle of lu'opod 3, rather 

 longer than broad, cleft "74 length, apices subtruncate, each with a spinule.
