" The naraing of Salmonida', and the description of new species, based 

 on the characters of young, partially grown fish, cannot be too strongly 

 reprobated. There is already too much confusion in the synonymy of the 

 different kinds j and if the practice of describing and naming new 

 species from the characters ol uiiidentitied immature individuals is not 

 stopped, the study of the relations of the species will become so com- 

 plicated, that useful classification will be next to impossible, and the 

 principal object and usefulness of scientific arrangement, such as sim- 

 plifies the study of natural history in other branches, will be greatly 

 impaired." — (Suckley, Monograph Salmo, p. 113.) 



The types of Salar leivisi are still preserved. The one figured by Girard 

 seems to be a, female specimen, in very flabby condition. It is quite deep- 

 bodied and has a smaller head and mouth than is usual in this species. 

 Other specimens from the same waters agree more or less comi)letely in 

 these respects with S. virginalis^ so that it does not seem possible to 

 con.sider the Missouri River Trout as even varietally distinct. 



The type.-! of Salmo carinatus I have not seen. They were from the 

 Yellowstone, and so far as the description is concerned seem to belong 

 to this species. 



The types of JSular virginalis are likewise preserved. They represent 

 the ordinary form of this sj^ecies in the Rocky Mountain region, and 

 hence are typical of what I (;all var. aurora. 



The original type of Salmo gibhsii, a stretched skin in poor condition, 

 is now lost. If the species is not identical wiMi Salmo clarJd, it is likely 

 to remain uncertain. 



Salmo clarki Richardson is identified by Dr. Giinther with Salmo pur- 

 puratus Pallas [Salmo mylciss Walbaum) of Kamtschatka. Giinther's 

 Salmo purpuratus, however, appears to be Salmo irideus, and not the 

 present species, and an identification of a fresh-water salmon from Cali- 

 fornia with a Kamtschatkan salmon Is very uncertain. In regard to the 

 migratory salmon, however, the case is different.
