southern Jalisco: southeast to Amula and the vicinity of Chilpan- 

 cingo, central Guerrero ; north to Nahuatzin and Patzcuaro, northwest 

 central Michoacan ; and west to the Sierra Nevada de Colinia, southern 

 Jalisco. 



The present race is most closely allied to Dryobates villosus jardinii, 

 from Vera Cruz, with which it practically agrees in size, but it is 

 nearly always much paler on the sides of head and neck, on the dorsal 

 stripe, and under surface. There are, however, occasional specimens 

 which, at first sight, appear to be like D. v. jardinii, but these are 

 never as deeply colored as the darkest examples of that form, or of 

 Dryobates villosus hylobatus, 1 particularly on the posterior lower parts, 

 throat, and light dorsal stripe. In having such a wide range of 

 individual color variation this race resembles Dryobates villosus 

 extimus. Four birds from the Sierra Nevada de Colima, southern 

 Jalisco, are larger than the others examined (wing of two males 

 averaging 119.5 mm.), and verge somewhat toward Dryobates 

 villosus icastus. 



Of this form 14 specimens have been examined, from localities as 

 follows : 



Guerrero. — Omilteme; mountains near Chilpancingo. 



Jalisco. — Sierra Nevada de Colima. 



Michoacan. — Nahuatzin; Patzcuaro; Mount Tancitaro. 



DRYOBATES VILLOSUS HARRISI (Audubon). 



Picus Jimrisi Audubon, Birds Amer. (folio), vol. 4, 1838, pi. 417, figs. 8, 9. 



Chars, subsp. — Resembling Dryobates villosus enissomenus, but very 

 much larger; lower surface more deeply colored. 



Measurements. — Male: 2 Wing, 124-136 (average, 127.8) mm.- 

 tail, 73.5-84 (7S.3); exposed culmen, 29-35 (31.7); tarsus, 22.5-25 

 (23.4); middle toe, 15-16 (15.4). 



Female: 3 Wing, 120-128 (124); tail, 74-82.5 (76.9); exposed 

 culmen, 26-31 (28.2); tarsus, 21-23.5 (22.1) ; middle toe, 14-15.5 (14.8). 



Type-locality. — Near Fort Vancouver, State of Washington. 



Geographical distribution. — Canadian and Transition zones in the 

 Pacific coast region of Alaska, British Columbia, and the northern 

 United States : north to Chichagof Island and Chilcoot, southeastern 

 Alaska; east to Boca de Quadra, coast of extreme southeastern 

 Alaska ; Hope and Agassiz, southwestern British Columbia ; Keechelus 

 Lake and Fort Vancouver, western Washington; Portland and 

 Crater Lake, western Oregon ; and south (excepting Prince of Wales 

 Island, Alaska, and the Queen Charlotte Islands, British Columbia) 

 to Humboldt Bay, northwestern California. In winter it wanders as 

 far south as Monterey, central California.
