REPORT OX A COLLECTION OF BIRDS MADE BY PIERRE LOUIS JOUY IN KOREA. By Austin II. Clark, Assistant Curator, Division of Marine Invertebrates, U. . s '. Xational Museum. The late Mr. Pierre Louis Jouy, during a residence of over three years in Korea within the period from 1881 to 1886, brought together a magnificent collection of the birds of that country, his specimens, live hundred and fifty-four in number, having been taken mainly at Fusan, Chemulpo, and Seoul, though a few are fromGensan. lie also visited the island of Tsushima in the Korean Straits, and obtained a very interesting series of the birds of that locality. This collection, much the most important ever made in Korea, has never been reported upon. Mr. Jouy was engaged in work upon it at the time of his death, and subsequently Dr. Leonhard Stejneger made use of some of the material in his studies on the avifauna of Japan. Although he pub-lished comparatively little upon it, he went over the collection care-fully and identified most of the species. It was suggested that, as I had spent considerable time in the vicinity of the Korean coast, an account of Mr. Jouy's specimens could appropriately be prepared along with the account of my own observations, and I therefore spent considerable time in the study of his material. This was, in the main, chiefly a review of the work already done by Mr. Jouy and Doctor Stejneger, and a confirmation of the results already attained by them. A preliminary notice of the new forms which 1 detected among the material studied was published in these Proceedings, vol. 32, pp. 407-475. While this preliminary notice was in press a paper appeared written by that eminent authority on Asiatic birds, Mr. Sergius A. Biiturlin, of Wesenberg, Esthonia, in which certain of my new forms w r ere anticipated. Mr. Buturlin has had the kindness to assist me in straightening out the matter, and he has recently published a note by which the confusion caused has been dispelled. I entirely agree Proceedings U.
