Hab. Middle region of U. So, from Atlantic to Pacific, and south to Guate- 

 mala. Cuba, Gundlach and Bryant. 



A winter specimen, from near Cape .St. Lucas, of P. cserulea, has 

 the ash of the back washed with a brownish tinge. I have not seen 

 this in any other specimens to anyi'uir.^ like the same extent. 



After a careful examination of Mexican specimens, labelled F. 

 meoncana by Mr. Yerreaux, nnd of others received from Gwateniala, 

 I am unable to distinguish them from P. cserulea. One of thesi', 

 No. 22,418 (.38,658 of \erreaux), has the black frontal line, and the 

 game pure bluish ash of northern specimens. The lores are perhaps 

 a little whiter than usual, not more ho than iu specimens from 

 Taniaulipas and Illinois. 



All these specimens from the south agree with northern cserulea 

 in the oiuall, rather narrow, falcate first primary, scarcely two-tliirds
