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. proxima. 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 specimen 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.
