mens. We gave the matter u]), however, only after shooting a very young 

 specimen of wliat was vindouljtedly unlliainsoni, and another of th//roi- 

 deus, both of which Nery closely resembled the adults of the same forms, 

 a circumstance wliicli at once convinced us that the differences could not 

 depend on age ; so we finally concluded that the two must be distinct. 

 Now, however, that Mr. Henshaw has so satisfactorily explained the case, 

 we liave no hesitation in iiuldrsing his opinion. 



We found this species both on the Sierra Nevada and in the Wahsatch, 

 and it is probable that its range extends throughout the entire Western 

 Kegion. It is confined to the coniferous forests, however, so that its dis- 

 tribution is governed greatly by local conditions. It appears to be con- 

 stantly pinicoline, since it was a winter resident among the pines near Car- 

 son City, while it was found in summer among those of the Wahsatch, in 

 Parley's Park. Excepting the circumstance of its being so strictly confined 

 to the coniferous forests, it resembles the other species of the genus in habits 

 and manners, Avhile the notes appear to be only very slightly different ; the 

 latter are finer and less plaintive, however, than in nuchalis or varius, and 

 uttered in nmre detached syllables. The female of this species presents 

 when flying a very close resemblance to the species of Centurus, the 

 plumage lieing similarly barred with black and wdiite, while a distinct 

 white area is presented on the lower portion of the rump. The first male 

 killed (No. i)31) had the bill thickly coated with the resinous juices of the 

 pine trees among which it had been feeding.
