GAMMA RID.®. 
perior antennm are about one-third of the length of the 
animal ; but the peduncle is more than twice the length 
of the flagellum. The inferior antennas do not reach 
beyond the peduncle of the superior. The first pair of 
legs are small, and have the hand ovate, the palm being 
oblique, slightly convex, and imperfectly defined. The 
second pair of legs are much longer than the first, and 
have the wrist very short, the hand is long-ovate, the 
palm oblique, and defined by a small point. The last 
pair of caudal appendages have the branches scarcely 
longer than the peduncle, and reach but little beyond 
the preceding pair. The telson has the apex of each 
division excavated, and furnished with two or three 
hairs. 
We have dredged this species oft’ Plymouth ; and have 
also received it from the Moray Frith through the kind- 
ness of the Rev. Geo. Gordon.
