The bird just described differs in several important characters 

 from two specimens collected on the tableland or eastern part of 

 Mexico in Mus. H. v. B., and I have little doubt belongs to a 

 new subspecies, which is perhaps more strongly marked than 

 other races of Certhice. At the first sight the Durango l)ird 

 differs by its much lighter and less rufescent coloration. The 

 spots on the head above and on the back are much broader and 

 more clearly defined. They appear to be nearly \\ bite, while tliey 

 are light rufescent in true mexicana. In the same wav the 

 markings on the sides of the head and on the wings are much 

 whiter and less rusty. The luuler parts, which in \.\\\e viexicana 

 are so much -suffused and mixed with fulvous, in the new form 

 appear nearlv pure white or grayish white. The rump is of a 

 darker chestnut. The outer margins of the outer webs of the tail- 

 feathers are more grayish or less rufescent. The bill is much 

 longer, measuring on tlie culmen 16] (instead of 14 to 15) mm.
