„Mandible having Ihe penultimate and last joints of the palp remarkably broad, 

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

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

 breadth. Antennules with peduncles short, first Joint equalMng the two following, 

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

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

 setae, which reach nearly half the length of the very short inner filament, which

in the described specimens has only thirteen articulations. Antennal scale ovate, 

 broad, with broad, well-rounded extremity; breadth two fifths of length; outer 

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

 extremity of peduncle of antennae; extremity reaching far beyond that spine; the 

 second Joint bearing six setae. Legs having tarsus composed of four or five arti- 

 culations. Telson cleft at the apex to rather more than one fourth of the length, 

 serrations of cleft unusually few and large (about 40); lateral margin with 16 — 17 

 spines. Inner uropods remarkably twisted and beut; inner margin with about 

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

 equal in length to the breadth of the uropod at that part; beyond this the uropod 

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

 Outer uropods much longer than inner, unusually parallel-sided; extremity widely trun- 

 cate, eigth setae taking their origin from this blunt extremity. Length 10 milim." (1. c.) 

 Verbreitung: Bisher nur bei Starcross, Devon gefunden.
