GAMMARIDEA. 



975 



Body rather slender, epimerals of moderate size; head oblong, the 

 front margin of either side with a projection, containing the eye. 

 Antennae elongate, inferior pair shorter than the body, third and 

 fourth joints long, subequal, flagellum a little shorter than base, 

 about ten-jointed, setae very short. Anterior feet small, the hand 

 and carpus together narrow elliptical in outline, short hirsute, 

 finger small. Hand of second pair very stout, <3-shape, the 

 immoveable finger being very much elongate, simple, and pointed, 

 and the hand projecting very far beyond its base, moveable finger 

 very long, longer than hand, the joints nearly equal in length, and 

 sparsely short hirsute. Third and fourth pairs of feet subequal ; 

 fifth pair with first joint having a narrow acute prolongation behind.

The large hand of this species with the closed finger is about as long 

 as the head and three anterior thoracic segments. The immoveable 

 finger is rather longer than the part of the hand projecting beyond its 

 base. The moveable finger is twice as long as the other, and when 

 closed, the apex of its first joint reaches to apex of immoveable finger, 

 and the whole of the second joint extends back along the length of 

 the immoveable finger. The setae within are in a few tufts. The two 

 hands of this second pair are equal. 



The superior antennae have the second joint of base longest. [The 

 flagellum was mutilated in the specimen examined.] The base of the 

 inferior pair much exceeds in length the base of the superior. The 

 epimerals have the margins rounded. The first joint of fifth pair of 

 legs has a tooth-like projection to posterior margin : this pair is about 

 half as long as seventh pair. There are but few setae.
