The existence of some form of White-breasted Nuthatch in the 

 Sierra San Pedro Martir has long been known. Anthony (1893, 

 p. 246) recorded his finding of the species there under the name 

 aculeata, brietly, as follows : ' ' Rather rare but well distributed in the 

 pines." But apparently no critical study of specimens, if any were 

 obtained, has until now been undertaken.
