Dryobates villosus orius Oberholser. Modoc Hairy Woodpecker. 

 Eleven specimens (nos. 17307, 19138-19147), from Helena, Scott 

 River, North Fork of Coffee Creek, and head of Bear Creek. This 

 series is on the whole darker on the breast and less spotted than 

 typical orius, but not to such a degree as to be referred to harrisi, 

 though intergradation in this direction is indicated. 



Dryobates pubescens gairdneri (Audubon). Gairdner Wood- 

 pecker. Four skins (nos. 17308, 17309, 19148, 19119), from Helena.

 but tend towards turati.

 headed Woodpecker. Two skins (nos. 19150, 19151), from Kangaroo 

 Creek, and head of Bear Creek, August 4 and 6. Seen also on

 sucker. Nine specimens (nos. 17310, 17311, 19152-19158), from

 bird was observed excavating a nest-cavity near the summit of a 

 dead Cottonwood. Bill-fulls of fine chips were repeatedly brought 

 to the doorway, and allowed to scatter to the ground immediately 

 about the tree. The bird finally emerged with an egg in its bill 

 and flew off with it over the fields. The bird soon returned and 

 resumed work upon the interior of the cavity, as evidenced from
