This new subspGcies may be distinguished from vharunturuH by the 

 (hirker, nnn-e rufi^seent. eoh»ration of th(^ upjier suifaee, sich's and 

 Hanks; tiie tail also averages appi'eciiahly sliort(M\ It is noticeably 

 lij?hter and rather n)ore grayish than npiluruH^ besides having a some- 

 what longer culmen. From rln/iHdcciis it is without diflienlty separable 

 by th(^ nolieeably darkei' and rather more sooty color of tlKi Hanks an<l 

 upper surfa.ee. Tln^ tail also averages slightly shorter. 



Four of the adult ".'xaniples, though summer biids in very iK)or con- 

 dition, are |)ra('tically i<lentica,l with the type, if anything somewhat 

 daik(!r. A July bird from Santa. Orn/ Island is rather lighter and 

 nion^ rufe8<;ent than the type, which, however, may be the result of 

 w«'ar, as the latter is in fresh winter plunuige.

 IVom those of chdriciilirniN, though they perhaps average more rufes- 

 cent. They are usually darker tlian the young of dri/maauH.
