42 Oberholser A New Otocoris from Lower California. 



flanks, thighs, and sides of breast and of body light brownish cinnamon; 

 rest of lower parts, including lining of wings, white. 



This new race is in color very similar to Otocoris alpestris leucolaema, but 

 is more grayish above, at least when in good plumage ; and has the eye 

 brow usually more yellowish ; furthermore, the greatly inferior size of 

 Otocoris a. enertera distinguishes it at once. From Otocoris alpestris actia, 

 whose range it approaches most closely, it differs very much more than 

 from either Otocoris a.ammophila or 0. a. leucolaema, being strikingly paler 

 and more grayish throughout, as well as somewhat smaller. 



The type specimen above described still retains some of the brownish 

 gray edgings of crown, jugulum, and cervix, but otherwise represents the 

 perfect breeding plumage. When badly worn, 0. a. enertera looks more 

 like 0. a, ammophila than when in fresh condition, though it is still more 

 grayish and pinkish above, and of course smaller. Otocoris alpestris enertera 

 appears to be non-migratory ; and its range, so far as known, extends in 

 Lower California from Santa Rosalia Bay to the neighborhood of Magda- 

 lena Bay.
