 Salmo sp., aiict. pi. 



This genus appears to be represented in Europe by the Salmo ohtusi- 

 rostris of Heckel or Thymcdlus microUvis of Steindachner ( Sitz. K. Akad. 

 Wissensch., 1. Abth., v. 70, p. 307, 1874),* which must therefore be 

 called Brachymy.stax ohtusirostris. That species, at least, does not ap- 

 pear to belong to the genus Salmo or Thymallus as generally defined, 

 and no generic differences between it and Brachymystax are evident 

 from the excellent figure and description.

Salinonids with a small mouth, short lower jaw articulating \vith the 

 quadrates under the eyes, and broad supramaxillaries with convex 

 adoral margins. 



The subfamily, besides the type genus, GoregonuH^ is generally made to 

 include Stenodus or Luciotrutta, but I have not been able to examine 

 a skeleton of the latter. It probably represents another subfamily.

* The identity of Salmo (or Salar) obtusirostris of Heckel and Thymallus microlepis 

 was recognized by Dr. Steindachner in 1882 (Sitz. K. Akad. Wiss., 1. Abth., v. 84; 

 Ich. Beitr. xii,p. 15). Nevertheless, in 1886, Dr. Seeley in '-The Fresh-water Fishes 

 of Europe," retained the two nominal species, Salmo obtusirostris (p. 286) and Thy- 

 mallus microl (pis (p. 358). If the genus Brachymystax is accepted the species in 

 question should apparently be referred to it.
