rower; tlie rufims oi' the rump is of a castaneous, instead of yellowish cast; 

 the wings appear more uniform with the back, owing to the dark color of the 

 latter, and their pale markings have little of that yellowish tinge so notice- 

 able in the others. In the ashy tinge of the lower ])arts there is a resem- 

 blance to familiaris of Europe; but the latter lias nut the ochraceous cris- 

 sum so noticeable in the present bird. There is little resemblance to Western 

 and Iiocky Mountain .specimens of the C. ainerimna ; and if these are to 

 be considered as separable Irom the Eastern (wliicli, however, would not, in 

 our opinion, be advisable) they must not be referred to tucxkami. 



The Mexican Creeper is introiluced here on account of the i)rol)ability of 

 its occurrence in the Southern Itocky Mountains. 



Habit.s. Mr. Salvin found the Mexican Tree-Creeper by no mean.s un- 

 common in the pine forests of the upper zone of the Volcan de Fuego. He 

 also observed it frequenting pine-trees in the district of Cliilasco, Vera Paz, 

 at al.iout 6,000 feet above the sea.
