Although in the British Museum Catalogue of Am- 
phipoda there are ten species described, yet this is the 
only one recorded as British, It was first taken by 
Col. Montagu, on the rocky shores of Devonshire, in 
pools left by the tide. Dr. Johnston recorded it as not 
rare in Berwick Bay (Zool. Journ. iii. 180). It has 
been taken frequently by us in Plymouth Sound ; we 
also found a large number of this species alone amongst 
the folds of a mass of rope which had been some time in 
the water, and which was dredged up by our friend 
Mr. T. P. Smyth. It has been sent to us by our valued 
correspondent Mr. Loughrin, of Polperro. Mr. Harris 
has forwarded it to us from Penzance ; and we have 
identified it with Milne Edwards’s type of G. Impostii, 
from La Vendee. 
It would appear from the circumstance of its being 
very abundant on the south of England, whilst we 
have never received it from our numerous correspondents 
from the north, (although it is recorded by Dr. Johnston 
at Berwick,) to be essentially a species belonging to 
warmer latitudes. 
It bears a near resemblance to M. tenella of Dana from 
the Fejee Islands.
