 the back deep black, bordered liy greenish olive, and margined with bluish gray, and in having 

 the flanks and sides streaked with dusky instead of witli bluish gray.

Macgillivray's Seaside Sparrow is known to be a summer resident on Pea Island, 

 where it breeds in late May; Bishop has also taken a few there in winter. 



The eggs are said to be usually four in number, whitish in ground-color, and 

 speckled or spotted with brown. 



232. Passerherbulus maritimus peninsulse (Allen) Scott's Seaside 



Sparrow.

 with greenish olive; the flanks and breast are streaked with dusky.

Scott's Seaside Sparrow claims a place in our list on the strength of a breeding 

 specimen in the United States National Museum, taken by Coues at Fort Macon, 

 April 15, 1869, and referred by Frank M. Chapman to this form. The different 

 forms are said to be very hard to distinguish except in the unworn winter plumage.
