AN ADULT TROUT. 225 



The 6th engraving on plate No. VII. is that of 

 a salmon-fry of between eight and nine months 

 old. In length it is four inches, and it is now 

 more deeply marked with transverse bars and 

 dorsal spots than at any other period. Those 

 spots are sometimes of a pink hue, sometimes 

 they are purple-coloured, and sometimes black. 

 The latter colour they assume after death. The 

 fish now resembles the little trout, called the parr; 

 but its fins are much longer than those of that 

 little fish, and its whole shape is much less per- 

 fect. Kot observing these marks of distinction has 

 led to the confounding of salmon-fry with parr ; 

 calling them, indeed, " parr," as Mr. Shaw and 

 his followers do; whereas the parr is a distinct 

 adult fish, of the river-trout species. I regret that, 

 owing to the season of the year at which I made 

 the application, I could not get a specimen of the 

 parr, to have it engraved and coloured, and placed 

 side by side with the salmon-fry represented on 

 the plate I am now describing. In answer to my 

 application, made from London, in November last, 

 to Mr. Young, at Invershin, he wrote: '* The 

 parr you want cannot be got at this season, in 

 consequence of the flooded state of the waters; 

 but from the description I will give, the artist can 

 easily engrave it. [I did not think so, and there-
