410 GAMMARIDiE. 



perior antennae are about one-third of the length of the 

 animal ; but the peduncle is more than twice the length 

 of the flagellum. The inferior antennae 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 off Plymouth ; and have 

 also received it from the Moray Frith through the kind- 

 ness of the Rev. Geo. Gordon.
