352 GAMMARID,E. 



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.
