Mr. P. L. Sclater on the Genus Spermophila. 13 



and S. nigricollis are certainly identical. I have lately also ex- 

 amined the types of these two species {Pyrrhula carulescens and 

 P. nigricollis of Vieillot), which are still in the Paris Museum. 

 Pyrrhula coerulescens is quite identical with the ordinary Brazi- 

 lian form of this bird. The type of P. nigricollis differs a little, 

 particularly in having a slight yellowish tinge on the belly, but 

 is, I fully believe, merely a not quite mature individual of the 

 same species. 



The specimens of this bird which I have seen from Buenos 

 Ayres {S. nigrigularis, Gould = /S. ornata, Scl. et Salv. P. Z. S. 

 1869, p. 682) have the head not quite so black as in most 

 Brazilian skins, and the back slightly suffused with olivaceous. 

 "When tirst met with in Mr. Hudson's series, their identity with 

 the Brazilian form was not recognized. 



Natterer collected a large series of this Spermophila in various 

 parts of S. Paulo, Bio, and Mattogrosso, whence it extends into 

 Bolivia and the Argentine Republic, but does not appear to go 

 further north.
