[There appear to have been two specimens of this species sent to me by Dr. Gairdner. In 

 both the spinal column contains sixty-two vertebrae. The teeth, which are closely set, rather 

 long, slender and acute, and, in the older specimen, considerably curved, are in number as fol- 

 lows : Intermax. lost; labials 28 — 30; palafe-bunes 15- — 17; vomer 13, two in front and the 

 others in a single flexuose series, as long as the dental surface of the palale-bones; lower jaw 

 13 — 13 ; tongue 6 — 6, in two almost parallel rows. The lingual teeth are the largest and most 

 curved, those of the lower jaw are next in size, then follow the vomerine, palatine, and labial 

 teeth, which are equal to each other. The pharyngeal teeth are also proportionally long, and 

 there is an oblong plate, rough with very minute ones, on the isthmus which unites the lower 

 ends of the branchial arches. This space is quite smooth in S. solar, in several, if not in all 

 the English trouts, and in S. quinnat, Gairdneri, and in the imperfect specimen which I have 

 referred to S. Scouleri. In the latter the surface of the arches is also quite smooth, but in the 

 quinnat and Gairdneri minute rough points become visible with a good eye-glass. In all the 

 trouts the compressed rakers have their thin inner edges more or less strongly toothed. In 

 one of the specimens of S. Clarkii the spinal column is nine inches long, in the other six. — R.]

" The Indian name of this fish is Oulachan. It comes annually in immense 

 shoals into the Columbia about the 23rd of February, hut ascends no higher than 

 the Katpootl, a tributary which joins it about sixty miles from its mouth. It 

 keeps close to the bottom of the stream in the day, and is caught only in the night. 

 The instrument used in its capture by the natives is a long stick armed with 

 sharp points, which is plunged into the midst of the shoal, and several are generally 

 transfixed by each stroke. It is the favourite food of the sturgeon, which enters 

 the river at the same time, and never has a better flavour than when it preys on 

 this fish. The Oulachan spawns in the different small streams which fall into the
