the island of Great Bahama. 



Specimens examined, 19, from the localities that follow: 

 Bahama Islands. — Abaco Island; Great Bahama Island.

Chars, subsp. — Similar to Dryobates villosus villosus, but decidedly 

 larger. 



Measurements. — Male: 1 Wing, 128-138 (average, 132.4) mm.; tail, 

 77.5-87 (83.5) ; exposed culmen, 31.5-37.5 (35.8) ; tarsus, 22-25 (23.5) ; 

 middle toe, 14.5-16 (15.3). 



Female: 2 Wing, 128-136.5 (130.8); tail, 78.5-90.5 (84.8); exposed 

 culmen, 29.5-33.5 (31.7) ; tarsus, 22-23.5 (22.7) ; middle toe, 13.5-15.5 

 (14.4). 



Type-locality. — Saskatchewan River, Saskatchewan, Canada. 



Geographical distribution.- — Hudsonian and Canadian zones of 

 northern North America: east to the Eskimo River, northeastern 

 Quebec [formerly Labrador]; south to Pointe de Monts (probably) 

 and Temiskaming, in central Quebec; northern Ontario; southeastern 

 and south central Keewatin; Fort Union, northwestern North 

 Dakota; Glasgow and Big Snowy Mountains, in northeastern Mon- 

 tana; southern Alberta; and Soda Creek (Caribou District), south 

 central British Columbia; west to Fort Grahame, north central 

 British Columbia; and Homer (Kenai Peninsula), middle southern 

 Alaska; north to Fort Reliance, central Yukon; Lake Hardisty, cen- 

 tral Mackenzie; Fort Churchill, central Keewatin; Moose Factory, 

 northern Ontario; and the Hamilton River, northern Quebec. In 

 winter it wanders southward as far as Rat Portage, western Ontario; 

 Roseau River (Kittson County), northern Minnesota; Fort Randall, 

 southern South Dakota; Harrison, northwestern Nebraska; Fort 

 Keogh and Corvallis, south central Montana; and the Similkameen 

 River, southern British Columbia. 



There is surprisingly little difference in size in this subspecies be- 

 tween examples from Montana and those from Mackenzie and Alaska. 

 Birds from northern Montana and central British Columbia have some- 

 what less white on the superior wing-coverts, showing thus a tendency 

 toward Dryobates villosus monticola. A single summer female from

2 Nine specimens, from Quebec, Alberta, Mackenzie, Yukon, and Alaska.
