Mar., 1913 A NEW RACE OF ROSY FINCH FROM THE SIERRA NENADA TABnE SHOWING FREOUENCY OF WING FOrmULA T--L. t. tephrocotis, 14 specimens.

The British American race, however, is believed to furnish the individuals which occur in winter in the northwestern United States south to eastern Oregon, Utah and Colorado. At least a winter specimen at hand from Camp I-Iarney, I-Iarney County, Oregon, is distinctly L. t. tephrocotis as here restricted. ?;M^?:s--There is no spring molt in the rosy finches', but marked color changes are brought about through wear. By this process, the extensively pink superficial portions of much of the plumage in its fresh fall condition is lost by the time the breeding season is at hand, the underlying brown colorat?on being thereby rendered much more conspicuous. It is thus necessary in diagnosing specimens on the basis of color characters, as well as of wing formula, to take into account the stage of wear reached. The tone of coloration in fresh juvenal plumage would appear to be more determinant than that in worn breeding adults. And lacking perfectly comparable specimens, in fresh fall plumage, of the two races here distinguished, a juvenal is selected as the type of the newly named form. The subspecific name given to the Sierra Nevada Rosy Finch is selected in recognition of the services to ornithology of William Leon Dawson. It has been the custom of systematists to signalize in like manner the work of fellow-system- atists, of collectors, of benefactors to scientific institutions. In the present in- stance it seems to the writer quite in accord with this happy custom to recognize an eminent service to the literary and artistic sides of bird study. Mr. Dawson has' contributed in this wise with marked success.
