342 GAMMA RIM. 



like processes ; these are slightly exaggerated in the 

 above figure. The eyes are small, round, and black. 

 The superior antennae are about half the length of the 

 animal, and support a short secondary appendage. The 

 inferior antennas have the peduncle quite equal in length 

 to that of the superior ; and the flagellum is about one- 

 third less than the flagellum of the superior. The 

 coxae of the four anterior pairs of legs are nearly as 

 deep as the respective segments to which they are 

 attached. The first pair of legs have the inferior 

 margins of the metacarpus, wrist, and hand tufted 

 with a short thick fur : the hand is about the same 

 length and about the same breadth as the wrist, it is 

 elongate-ovate, having the palm oblique, imperfectly 

 defined, slightly convex, and armed with short, stiff, 

 equi-distant hairs : the finger is sharp and curved. 

 The second pair of legs have the wrist short, with the 

 inferior angle produced to a point, as is also that of the 

 preceding joint : the hand is large, quadrate, broadest 

 at the palm : the finger, which impinges laterally to 

 the palm into a hollow formed by a lateral denticle and 

 the inferior angle of the palm, resembles, in its form, 

 a Turkish scimitar ; the outer margin being somewhat 

 rounded, and the extremity obtuse, a form also peculiar 

 to some other species of this genus. All the other legs 

 are subequal in length ; and the three posterior have the 

 thighs with their margins entire. In the few specimens 

 that we have taken of this species the posterior pair 

 of caudal appendages are wanting ; but in Montagu's 

 type, in the British Museum, from which our figure was 

 drawn, it does not differ from that of the two following 

 species. 



This description is taken from a fresh specimen 

 dredged in Plymouth Sound ; the figure, with which we
