Salmo nitidus, Richards. Faun. Bor.-Amtr. iii. p. 171, pi. 82. fig. 1, 

 and pi. 86. tig. 2. 



B. 11. D. 13. A. 12. L. lat.215. 



Body somewhat elongate ; head of moderate size, its length being 

 one-fifth or rather more than one-fifth of the total (without caudal) ; 

 snout of moderate extent ; maxillary straight, strong, extending in 

 the male behind, and in the female to, the vertical from the hind 

 margin of the orbit. Teeth of moderate size. Teeth not only on 

 the head of the vomer, but also two or three behind it. Prfeoper- 

 culum with the lower limb very distinct. Fins well developed ; the 

 length of the pectoral is one-half, or rather less than one-half, of the 

 distance between its root and that of the ventral. Caudal fin con- 

 spicuously emarginate, the length of the middle rays being one-half 

 of that of the longest. 



These characters are taken from the typical specimen, a male, 21 

 inches long, from a small lake in the peninsula of Boothia. A second 

 specimen, preserved in the Haslar Collection as S, hoodii, proves to 

 be not one of the tj-pical specimens of that species, but is undoubtedly 

 a female of S. nitidus ; it is also 21 inches long. 



25. Salmo hoodii.

We believe that Richardson has confounded at least two species 

 under this name : —
