T^A Miller, New Jay from Mexico. j^ From the series of hyloscopus examined I would not consider that it is ever " pure white " below, though always much nearer white than harrisi. There is always a slight smoky brown or soiled appearance to the plumage of the breast and belly, quite noticeable in contrast with the Rocky Mountain race. I have never seen a specimen from California that I should call typical harrisi, though a few of the more northern skins are rather near that race, and a specimen from Lake County, California i Barrett Mt.) is much nearer //arris/ than hyloscopus. The habitats of the three western races might be maped as follows : Dryobates villosus harrisi. — From British Columbia south to northern California (Barrett Mt.). D. villas us hyloscopus. — California south to San Pedro Martir Mts., Lower California, east to Chiricahua Mts., Arizona. D. villosus montanus. — Northern New Mexico, north to Montana and Idaho. Utah (Uintah Mts.). DESCRIPTION OF A NEW JAY FROM MEXICO. BY GERRIT S. MILLER. JR. An undescribed Jay collected by Mr. W. B. Richardson in the mountains near Bolahos, Jalisco, Mexico, in February, 1889, differs in many ways from Aphelocoma couchi Baird, its nearest relative. It may be called Aphelocoma gracilis, sp. nov. Sp. C/i. — A little smaller than Aphelocoma couchi Baird and with dis- proportionately slender bill and weak feet; color throughout much grayer than in A. couchi. Adult, male (Type No. 5658. collection of Gerrit S. Miller, Jr., Sierra Bolanos, Jalisco, Mexico, February 26, 18S9. W. B. Richardson collector) : Back smoke gray faintly tinged with blue: rump, upper tail-coverts,
