188-J.] HYBRIDS AMONG THE SALMON! DM. 25

It would appear, from the foregoing, that out of 22 specimens of 

 Mr. Wilmot's young Salmonidae, the number of parr-bars varied 

 from 7-10, frequently differing in numbers in the two sides of the 

 same fish, while the average was 8^, a remarkable difference from 

 what obtains in the British Salmo salar, a question I shall refer to 

 again further on. I may, however, mention here that in some of 

 these fishes the bars were much broken up. The adipose fin in 

 almost all had a leaden-coloured base, the outer two thirds being 

 orange-coloured. 



When leaving Teignmouth in Devonshire, in 1882, 1 had the oppor- 

 tunity of seeing, but not of procuring, two or three long and lanky 

 Salmon, having much the appearance of kelts. 1 had, however, 

 to postpone my investigations, and went there in August this year, 

 when I was so fortunate as to find the same class offish, not only in 

 the market there, but also at Torquay, where I went likewise to 

 inquire respecting these fish. In fact, out of the many Salmon which 

 I saw, all were of this local race, evidently the Salmo gracilis, Couch, 

 whose examples were taken in the Fowey. Tarrell, on being sent a 

 figure of Couch's fish, replied, " I have a skin of a Salmon that 

 would have been a good match for your female. This was a Salmon 

 that had been detained in a fresh-water pond rather more than three 

 years." Yarrell suggests the water did not suit Couch's fish, but 

 the latter author observes, " It had just come from the open sea," and 

 that the Fowey water is not polluted with poisonous water from 

 mines. It appears to be a variety or local race of S. salar. 



In the foregoing the proportion of the depth of the body to the 

 total length was about b^ times.
