no. 1840. REVISION OF HAIRY WOODPECKERS— OBERHOLSER. 613 



Durango; and Sierra de Nayarit, eastern Tepic; south to Huajimic, 

 southeastern Tepic; Bolanos, northern Jalisco; and Plateado, south- 

 western Zacatecas; east to Carneros, southeastern Coahuila; Bus- 

 tillos, west central Chihuahua; and Pacheco, northwestern Chi- 

 huahua. 



This bird is decidedly smaller than Dryohates villosus leucothorectis, 

 as well as noticeably smoky-tinged on the under surface, instead of 

 pure white; and it is in size so very much inferior to Dryohates villo- 

 sus orius, that it is readily distinguishable. 



Birds from Zacatecas, northern Jalisco, and eastern Sonora <nie 

 identical in size with those from the type-locality in Durango. 

 Specimens from Coahuila (Carneros and Sierra Guadalupe) are 

 somewhat smaller — about the size of Dryohates villosus intermedins — 

 (wing of male averaging about 118.5 mm.), but are so much paler 

 below that they are best referred to the present race. Examples at 

 hand from southeastern Arizona (north to Pinal County) and extreme 

 southwestern New Mexico (Animas and San Luis ranges) are some- 

 what less smoky brownish below, but average fully as small as those 

 from Durango, and also belong here. The birds from Chihuahua, 

 to judge from the six of each sex examined, are larger than those 

 from any other part of the range of this subspecies and average as 

 follows : 



Male. — Wing, 126.1 mm.; tail, 73; exposed culmen, 29; tarsus, 

 20.8; middle toe, 14.2. 



Female. — Wing, 124.8; tail, 75.6; exposed culmen, 25.9; tarsus, 

 20.1; middle toe, 12.6.
