LIST OF THE FISHES OF BERWICKSHIRE. 171 



(b.) Half-armed Stickleback, Yarr. 



(c.) Smooth -tailed Stickleback, Yarr. 



(d.) Four-spined Stickleback, Yarr. 



Dr Parnell, in May 1836, took two specimens of the last in 

 the pools left by the tide on Yarrow-haugh, Berwick ; and he is 

 of opinion that it is different from the four-spined Stickleback of 

 Yarrel, but the only difference I can perceive is, that the 2d ray of 

 the dorsal fin is shorter than the 1st or 3d, while in Van-ell's they 

 appear to be nearly all of the same size. Dr P. agrees with those 

 authors who consider all the varieties as properly constituting dis- 

 tinct species ; but because they are to be always met with in the 

 same pools, living and mixing freely together, and because it is 

 not seldom difficult to refer a specimen to its supposed species, 

 from an obscurity or commixture of characters, I have preferred 

 following the example of Mr Jenyns, in his Manual of our Native 

 Vertebrate Animals.
