announced this important addition to the North American fauna. 

 The series obtained by Mr. Stephens comprises nine specimens, 

 all of which were taken near Morse's Mill. They occurred upon 

 the sides or summits of the surrounding mountains, at elevations 

 varying from seven to ten thousand feet, and were usually found 

 in pairs, although they not unfrequently associated with other 

 birds, among which are mentioned Psaltriparus plunibeus^ Lo- 

 phophanes ivoliweberi, Sitta pvgtncea^ and Peticedramus oliva- 

 ceus. Thev were for the most part silent, but occasionally 

 uttered a "^chee-ivee-ivee^'' as well as notes reseinbling those of 

 P. montanus. 



Previous writers have compared this species with P. atricapillus. but to 

 me it seems nearer related to P. motita)ins. With the latter it agrees in 

 certain peculiarities of size and proportions, while the general coloring 

 and markings of the two are so similar that almost the only appreciable 

 points of diiference are presented by the white forehead and head-stripes 

 of montanus. These characters are, of course, enough to instantly sepa- 

 rate the birds, but their importance is somewhat weakened by the fact that 

 one of my specimens of inertdionalis (No. 124) possesses a head-stripe 

 which, though ill-defined and considerably shorter, is nevertheless similar 

 in appearance and position to that o^ tnonta?n/s. While it would be rash to 

 argue any varietal affinity on the strength of this single specimen, the 

 outcropping of such a w"ell-marked characteristic certainly shows a close 

 relationship between the two species, unless indeed No. 124 be legarded 

 as a hybrid.
