NO. 2265. THE WREN GENUS NANNU8 BILLBERG—0BERH0L8ER. 235 



Measurements. — Male:^ wing, 49-49.5 (average, 49.3) mm.; tail, 

 30.5-32 (31.3) ; exposed culmen, 11.5; tarsus, lG.5-17.5 (17) ; middle 

 toe without cLnv, 12. 



Type-locality. — English Bay, near Kodiak, Kodiak Island, Alaska. 



Geographic distribution. — Kodiak Island. 



Remarks. — This island race is similar to Nannus troglodytes ala- 

 scensis, but is smaller throughout; slightly more rufescent on the 

 upper surface, the dark bars on the posterior portion being more 

 conspicuous ; and it averages darker below. With the better material 

 of Nannus troglodytes alascensis now available, it is readily seen that 

 the present race intergrades with that form by individual variation. 

 Very few specimens of the present race exist in collections, and it 

 thus is still one of the rarest American forms of the genus. 



Detailed measurements are as follows :
