OF EASTERN PENNSYLVANIA. 331 



The eggs are a uniform light blue, and present 

 a similarity in tint to those of the Sialia sialis of 

 Baird. They measure, on an average, .84 of an 

 inch in length, and .65 in breadth. 



Euspiza townsendii, Bonap.

 it is a good species, or merely an abnormal plumage 

 of the last." Nothing is know of its history.

 a feeling of dread, and leads to its hasty depart-
