408 GAMMARID^^ 



but the palm is serrated and defined by a distinct tooth. 

 The posterior pair of caudal appendages are wanting in 

 each of the specimens that we have seen. In the Cata- 

 logue of Amphipoda of the British Museum, this pair of 

 appendages is represented as having one branch very long 

 and the other nearly rudimentary, in which respect the 

 animal differs from the remainder of the British species 

 of this genus. 



The character of this animal appears to justify its 

 admission as a species in the present genus, but we desire 

 to express our conviction that it will ultimately be 

 ascertained to be the female of a species of Melita, 

 probably M, jjroxiina. A similar consideration induces 

 us to forbear adding two or more species which, as we 

 observed in page 336, only differ in the form of the 

 hands from certain species of the genus Melita. 



Our first sjDecimen of this species was received from 

 the eminent naturalist after whom we have named it, and 

 by whom it was dredged on the coast of Northumber- 

 land. We have since obtained it from Mr. Edward of 

 Banff.
