Notice of the Parr. By Sir WILLIAM JARDINE, Bart. 



THE fishes inhabiting the rivers of Berwickshire are comparatively 

 limited in the numbers of their species, but some of them are of much 

 importance and value, while others, as the little fish we are now about 

 to notice, although abundant, and familiarly known as a parr, has yet 

 some unrivalled mysteries in its history, and there are, I believe, only a 

 few persons at the present time, who are able to say what it really is, 

 or to point out the distinctions which separate it from its congeners. 

 Among naturalists generally, an uncertainty seems to have existed whe- 

 ther this fish was the young of some of the migrating salmon ; but more 

 lately, this opinion seems to have resolved sitself into this, whether the 

 parr was a species, or only the young or a variety of the common river 

 trout. The following observations are the result of comparisons made 

 last month between Tweed specimens of the parr and S. Fario. We 

 shall first, however, shortly notice the habits of the former. 



Among the British Salmonidae, there is no fish where the habits are 

 so regular, or the colours and markings so constant. It delights in the 

 clearest streams, with rocky or gravelly bottoms, and seems pretty ge- 

 nerally distributed in Britain in those which have this character ; but is 

 not at all found in the low and flat districts, where the waters are deep 

 and sluggish. It frequents the shallower fords, or the heads and lower 

 parts of streams, in shoals, hanging nearly in one place, and in constant 

 activity from the exertion, apparently day and night. It takes any bait 

 with the greatest freedom at all times, and when no trout, though abun- 

 ant among them, will rise or bite. That part of its history which is 

 et unknown is its breeding. Males are frequently found so far ad- 



1 The species of Enicocerus and Elmis were found in plenty under stones in the bed of 

 the Whiteadder, particularly just below tlie bridge nearest to Berwick.
