Stripe of Prout's brown, with narrow black sliaft streaks ; cincrca 

 in corresponding plumage has these stripes more distinct, and of 

 a burnt umber color. Kadiak birds have less white below than 

 most specimens of dnerea, and the whole plumage is a shade 

 darker. The specimens of cincrca from the various localities 

 represented are quite uniform in coloration, but the size varies 

 slightly, those from Sannak leaning somewhat toward insignis in 

 the slender shape of the bill, although the measurements slightly 

 exceed those of the Unalaska individuals. In this connection it 

 may be mentioned that two examples from Cook's Inlet on the 

 mainland (Nos. 81,380 and 131,730) approach insignis much 

 closer, both in color and size, than individuals of rufina from 

 Sitka, and it may be found necessary, upon the examination of 

 more material from this region, to either merge these birds into 

 insignis, or separate them from riifina under a new title, f^insch's 

 Alexandrovsk specimen is probably similar to these mainland 

 birds. Measurements of the two specimens mentioned will be 

 found following those of M. insignis in the following summary.
