THE CONDOR Vol. XVI forms me that he now has serious doubts as to the accuracy of his identification of this species at Sitka. l?arus ,?tric?pillus. I?yloeiehls slieise. Recorded by Dall. Professor Cooke informs me that there are no specimens of either of these two latter forms in the Bischoff collec- tion in the National Museum. Neither are there specimens of any other forms that could have been confounded with them. He' considers the publication by Dall of their being taken at Sitka by Bischoff to be a mistake of the writer. LITERATURE CITED 1850. Bonaparte, Charles Lucian. Conspectus Avium, 1, 1850, p. 477.
