Bartram has all his Wood- 

 peckers right, under prior arid 

 tenable names ; and his list 



00 ; includes every one of the East- 



36. Centurus carolinus. _ t . , J 



ern United States, excepting P. 



querulus. No. 32, for "white 



back" read "white beak." 



37. Picus pubescens. 



38. Picus villosus. 



39. Sphyropicus varius. 



40. Sitta carolinensis. 



41. Sitta canadensis. Here is obviously the origin of Wilson's term, 

 S. varia. 



42. Certhia RUFA (Bartr.) ! Nomenclature binomial, and description 

 diagnostic ; the name should stand with those who separate the bird from 

 the European.

 Wilson, but we here see its original source. 



44. Mniotilta varia. "Blue and white" is an evident slip for " black
