CERTIIIAD.E — THE CREEPERS. 129 



rower ; the rufous of tlie rump is of a castaneous, instead of yellowish cast ; 

 the wings appear more uniform with the l«ick, 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 tlie lower parts there is a resem- 

 blance io familiariH ol Europe; but the latter has not tlie ochraceous cris- 

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

 and Rocky Mountain specimens of the C. mmrimna ; and if these are to 

 be considered as sejiarable from the Eastern (which, however, would not, in 

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



The Mexican Creeper is introduced here on account of the jjrobability of 

 its occurrence in the Southern IJocky Mountains. 



Habits. Mr. Salvin found the Mexican Tree-Creeper by no means un- 

 common in the pine forests of the upper zone of the V(jlcan de Fviego. He 

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

 at about 6,000 feet above the sea.
