May (F. J. Huse). 



Tanagrid^e.

Fringilliile.

38. Pocecetes gramineus Bd. Bather common. 



39. Coturniculus passerinus Bon. Rather common.

41. Zonotrichia leucophrys Swain. Quite common. 



42. Zonotriehia albicollis Bon. Common. 



43. Spizella pusiUa Bon. Not apparently common. 



44. Spizella socialis Bon. Not conspicuously numerous, as at the east. 



45. Mehspiza melodia Bd. Rather uncommon. Indeed it was so scarce that we rarely 

 noticed it. 



46. Mehspiza Lincolnii Bd. Common. Much more numerous than the preceding.

In winter, according to my friend Mr. F. J. Huse of Evanston, the northern species of this 

 family, as Spizella monticola Bd., MgiMhus Unarms Cab., both Crossbills, Plectrophanes nivalis 

 and P. lapponicus, and Pinicola enucleator (P. canadensis Cab.) occur, some of them regularly 

 and otliL-rs irregularly, about as in the Atlantic States, excepting perhaps P. lapponicus, which 

 is more common at the west. The prominent difference in the representation of this family 

 here and in New England at this season (May), is in the relative scarcity here of the 

 Spizelke and Mehspiza melodia, the most numerous species in New England, and the greater 

 commonness of Mehspiza Lincolnii, Euspiza americana, and Zonotriehia leucophrys, the first two 

 being almost unknown there, while Chondestes grammaca is wholly superadded, giving, as will
