found in the same situation as the preceding species, 

 namely, sandy fields. 



80. Zonotrichia leucophrys, Swain. — White-crowned 

 Sparrow. Very rare migrant. Took a female on May 

 27, 1869, in a swampy thicket by the roadside. I have 

 heard of but few instances of its capture in this section. 



81. Zonotrichia albicollis, Bon. — White-throated 

 Sparrow. Common during the migrations. Have taken 

 it from April 27th until May 20th, and from about Sep- 

 tember 1st to October 19th. Frequents the low bushes 

 and swampy thickets. 



82. Ammodromus maritimus, Swain. — Sea-side 

 Finch. Said to occur commonly along the coast of our 

 State, which statement I doubt, as 1 have searched care- 

 fully for it from the mouth of the Merrimack River to the 

 extreme south shore, and have yet to meet with a single 

 living specimen ; neither does it occur on the Island of 

 Nantucket to my knowledge. Dr. Coues says it is abun- 

 dant in New Hampshire on the coast. It may rarely occur 

 on our coast during the migrations. Mr. Brewster informs 

 me that he has looked for it in vain at Rye Beach, New 

 Hampshire. 



83. Ammodromus caudacutus, Swain. — Sharp- 

 tailed Finch. Not common. I know of but one locality 

 where this bird is to be found ; that is, on the salt marshes 

 of Charles River. I have taken it there in the latter part 

 of June. It is difficult to procure, as it lies close, and has 

 to be shot while on the wing. It instantly conceals itself 

 in the grass when it alights. Mr. Brewster informs me 

 that it breeds late, — the first week in July. Remains late. 

 " Have taken it in the marshes of Charles River the last 

 week in October." * Since writing the above, I have found 

 it quite common on the marshes at Ipswich during the last 

 week in September, 1869.
