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
