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

 Mr. Wihnot's young Sahnonidae, 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 tnken 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.
