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 opportunity of seeing, but not of procuring, two or three long and lanky Salmon, having much the appearance of kelts. I had, however, to postpone m y 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.
