SPIZELLA. iil 
The eggs of the Chipping Sparrow are of a pointed oval shape and 
moderately glossy. They are greenish-blue, spotted and blotched, 
almost entirely at the broad end, with dark purplish-brown or 
black, and lilac-grey or pinkish-brown. The markings are sparse 
and small in size and rarely extend to the smaller half of the egg. 
Specimens measure from °6 to *72 in length, and from ‘5 to 55 in 
breadth.
