YOUNG SALMON, A PARR. 75 



by the presence of the bluish-grey or olive transverse bands 

 alluded to above^ and figured in the cut of Pinks, at the head of 

 this article ; as also again in the plate at the head of that on the 

 Brook Trout {Salmo Fontinalis), next following. 



Concerning this little fish, there has been a continual doubt, 

 and a dispute of many years' standing, some persons maintain- 

 ing that it was a distinct and reproductive species of the 

 Salmonicla, which they termed variously Parr, Samlet, Brand- 

 ling, and so forth ; others, from its never being taken of any 

 size, have believed it to be an vmproductive cross, or mule, 

 between the Salmon and the Common Trout, the Sea Trout and 

 Common Trout, &c., &c. ; and others yet again, that it was 

 neither more nor less than a young Salmon. 



In proof of this, it was adduced that Parr had been marked 

 and retaken as Grilse. 



But in reply, it was stated that Parr had also been marked 

 and retaken as Bull Trout {Salmo Eriox), and Salmon Trout 

 [Salmo Triitta) ; whence it was argued that the fish marked had 

 been marked carelessly and injudiciously, and were not Parr 

 at all, but Smalts, or fry of some of the other Salmonida. Mr. 

 Yarrel admits that he has seen these vertical marks in the 

 young of the Salmon, Bull Trout, Parr, Common Trout, and 

 Welsh Charr ; but still maintains the existence of the Parr as 

 distinct, principally on the ground that the Parrs are taken 

 abundantly even in autumn, not exceeding five inches in length, 

 long after the fry of the larger migratory species have gone 

 down to the sea. 



This is in the body of the work, written previous to the 

 experiments made by Mr. Shaw, and this Mr. Yarrel there
