Distribution. I know of no record beyond the British seas, 

 unless Lilljeborg's and Zaddach's species are synonymous 

 with the present. 



The telson of this species (PI. XII. fig. 13) terminates in 

 three spines and as many (or about as many) setas ; towards 

 the base is a group of three spines, and between this and the 

 extremity two sette having their bases close together, and 

 sometimes accumpanied, as in the figured example, by a 

 small spine. 



4. Gammarus tenuimanus, Bate. 



1802. Gammarus tenuimanus, Bate, Cat. Amphip. Brit. Mus. p. 214, 

 pi. xxxviii. lig. 2 ; Bate & Westw. Brit. Sessile-eyed Crust, vol. i. 

 p. 384. 



Described from a single specimen which was found by 

 Mr. Spence Bate among a lot of Crustacea sent to him by 

 the Rev. G. Gordon from the mouths of the Rivers Ness and 

 BrauUy, which flow into the Moray Firth. It is unknown 

 to me. 



5. Gammarus Edwardsii, Bate. 



1862. Gammarus Edivardsii, Bate, Cat. Amphip. Brit. Mus. p. 208, 

 pi. xxxvii. fig. 2 ; Bate & Westw. Brit. Sessile-eyed Crust, vol. i. 

 p. 380. 



This species is also unknown to me. The two known 

 specimens were found by Mr. Spence Bate in a pool into 

 which the tide formerly flowed, but which is now of fresh water, 

 at Starcross, Devon. Mr. D. Robertson recorded this species 

 in his Contrib. to Cat. Amphip. and Isop. of Firth of Clyde, 

 1888, p. 94, but is now satisfied that the specimens must be 

 referred to the young of other species.
