1889. Melphidippa macra, Norman, "Notes on British 

 Amphipoda." Ann. and Mag. Nat. Hist., sen 6, vol. iv., 

 p. 121, pi. X., fig. 14, and pi. xii., figs. 4-7.

 fathoms (A. Mk.) D. 



Fam. 19.— GAMMARID^ 



Amathilla homari {¥a.hx\c\\xs)=iAmathilIa Sabini Bate= 

 Graia imbricata Bate (the young). 

 Very common in rock pools and between tidemarks, as well 

 as in shallow water. We cannot see specific difference between 

 A. angulosa and the young of this species, of which Grata 

 imbricata Bate is a still younger condition. N.D. 



Gammarus marinus Leach. 



Ryhope, tidemarks (A. M. N.); Sunderland (G. S. B.); 

 common on the coast (A. Mk.) N.D. 



Gammarus locusta (Linne). 



Abundant between tidemarks and in lammarian zone. 



N.D. 

 Gammarus Duebeni Lilljeborg. 



1889. Gammarus locusta van, C. Hoek, Crustacea

1889. Gammarus campy lops, Norman, Notes on British 

 Amphipods. Ann. and Mag. Nat. Hist., sen 6, vol. iv., 

 p. 139, pi. xii., fig. 13. 



We follow Sars here in using Lilljeborg's specific name, but 

 we are by no means convinced that the species is not the 

 G. campy lops of Leach. 



Brackish water, Bamburgh, and Hartlepool Slake(A.M.N.); 

 common in the Coquet about a mile from the mouth of the 

 river; in a drain flowing into the Blyth (A. Mk.) N.D. 



Gammarus campylops (Leach) G. O. Sars. 

 One specimen from the river Blyth (A. Mk.) N.
