„Mandible haviny Ihe peniiltimate and last joiiits of the palp remarkably broad, 

 the latter more so than in any otlier member of the genus, scarcely more than 

 twice as long as broad. Eyes nearly globular, length scarcely exceeding the 

 breadth. Antennules with pedimcles short, first Joint eqtialling the two following, 

 second Joint traiisversely narrowly triangulär, third Joint expanded and very broad, 

 breadth exceeding length; distally furnished with a circlet of very long plumose

 broad, vvitii broad, well-roiiiided extremity; breadth two fifths of length; onter 

 margin naked, terminating in a large spine which is just on a level with the 

 extremity of peduiicle «f anteniue; extremity reaching far beyond that spiiie; the 

 second Joint bearing six sets. Legs having tarsus composed of four or five arli- 

 cnlations. Telson cleft at the apex to ratlier more than one foiirth of the length, 

 serrations of cleft umisiially few and large (about 40); lateral margin with 15 — 17 

 spines. hmer uropoils remarkably twisted and bent; inner margin witli about 

 15 spines on its central portion, of whici) the more distal are of great size and 

 ec]nal in length to the breadth of the uropod at that part; beyond tliis the uropod 

 is very narrow, and just before the extremity there is a Single very large spine. 

 Outer uropods mucli longer than inner, unusnally parallel-sided; extremity widely trun-
