PARR. 47 



third less. These are the most conspicuous distinctions, 

 but every bone varies ; and not in one only, but in the many 

 specimens which I have lately examined, the distinctions 

 were the same, and at once to be perceived. In this state, 

 therefore, I have no hesitation in considering the Parr 

 not only distinct, but one of the best and most constantly 

 marked species we have, and that it ought to remain in our 

 systems as the Salmo salmulus of Ray." * 



By the kindness of various friends, I have received Parrs 

 from several rivers on the east, south, and west shores ; and 

 from close comparative examination of specimens from dis- 

 tant localities, and these with the young of others of the 

 Salmonida, I believe the Parr to be a distinct fish. The 

 largest I possess measures full eight inches, and was sent 

 to me by Dr. George Johnston, with several others not more 

 than five inches long, from the Tweed, and taken in the 

 month of July. The representations which illustrate this 

 subject were taken from these specimens. The smallest 

 Parr I have preserved measures but three inches and one 

 quarter, and was sent me with others nearly double the size 

 by Sir William Jardine, Bart. : these were taken in summer 

 from the Annan. I have also received Parrs, the Skirling 

 of Pennant, not exceeding four inches in length, from 

 Glamorganshire and from the Ribble, in June, as well as 

 from other localities between the Tweed and the Annan. 



An opinion prevails that the Parrs are hybrids, and all of 

 them males. Dr. Heysham, at different times and seasons, 

 opened and examined three hundred and ninety-five Pan-s, 

 or Samlets, as they are called at Carlisle, and found one 

 hundred and ninety-nine males, and one hundred and ninety- 

 six females. I am indebted to J. C. Heysham, Esq. for
