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 antennae 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
