Schofield THE Montana grayling orig- inally existed only in the tribu- taries of the Mis- souri river above Great Falls and was noticed by Lewis and Clark during their jour- ney to the Pacific Coast. Lewis and Clark alluded to it as a new kind of white or silvery trout. In 1S72 James W. Milner of the U. S. Fish Com- mission discovered this same specie in a tributary of the Missouri near Camp Baker, Montana, and after describing same named it Th.\mallus montanus. While it is closely related to t...he Arctic grayling (T. signitier), there is enough differ- ence between the two so that each is now given a specific rank. It is probable that the Arctic gray- ling was the parent stock from which the Michigan and the Montana grayling descended, and from the fact that the habitats of the three species are so widely separated it is not unreasonable to suppose that the Michigan and Mon- tana forms were conveyed thence from the Arctic regions during the Glacial period. This theory is strengthened by the fact that Elk Lake, a half mile from the Montana grayling station, is abundantly inhabited by both grayling and lake trout fCrestivomer namay- cush), which latter fish is found no- where else west of Lake Michigan.
