ery beautiful specimen and a most typical example of the silver trout. Professor Jordan described this fish as a new species, under the name of _Salmo kamloopsii_, and he so describes it in a monograph on the salmon and trout of the Pacific Coast, published by the State Board of Fisheries for the State of California. In this account he gives expert reasons, founded on the number of rays in the anal fin and tail, the position of the opercula, and the size of the body scales, suggesting, moreover, that the fish might turn out to be a connecting link between the true salmonidae and the genus oncorhynchus or Pacific Coast salmon. He suggested that a further specimen should be sent, in order that the intestinal tract might be examined; but this suggestion was unfortunately not complied with. I am not prepared to say whether Professor Jordan still adheres to this opinion, or whether the silver trout has been fully recognised among ichthyologists as a distinct species. In a recent letter to me, however, he states that he considers the Kamloops trout to be "only a slight variation of the steel-head," which statement shows that its exact identity is not established, for the steel-head is absolutely unknown in these upper waters, and the silver trout never goes down to the sea. To the best of my belief it is a fact that no further specimens have been examined by any naturalist of note, and the question is therefore still _in statu quo_. It is a matter, I would humbly suggest, that is well worthy of solution. So far as I am aware, Professor Jordan is the only expert who has examined this fish. The only other evidence as to its existence as a distinct species is the widespread local opinion, which is also held by the half-breeds and Indians, who undoubtedly believe that there are two kinds of trout in the Thompson River. Such evidence or belief is not scientific proof, but is certainly of considerable weight, until it is proved to be mistaken. I have always been firmly convinced that the two fish are perfectly distinct, and this opinion is fully shared by all the local anglers. If two well-marked specimens are seen side by side the difference in appearance is most remarkable. The silver trout is less heavily built, the head is smaller and sharper, the scales are smaller in size, and the stripe on the side is violet instead of pink. There is only one alternative opinion, namely, that for an unknown reason some rainbows acquire t
