HABITS. 



Lincoln's Sparrow is not a common New England migrant Imt occurs regular!}' in 

 certain locations; thus, they are not uncommon near the Fresh Pond marshes, Cambridge, 

 and at Concord, Massachusetts. I also fuund tiiem conunon in autumn at Watsontown, 

 Pennsylvania, where they frequent the thick gr;<ss and bushes along streams, and in gen- 

 eral habit resemble Swamp Sparrows. 



PEUCAEA AESTIVALIS BACIIMANII. 

 Bachman's Sparrow. 



DESCRIPTION. 



Sub Sp. Ch. Similar in size, form and general coloration to the Pine Wood Finch, but differs in hav- 

 ing a larger bill, and with brrnvn streaks above these being confined to the middle of the back, while the 

 breast and sides are more buffy. This is the more northern form, occurring from the Carolinas to Illinois. 



PETROCHELIDON FULVA. 



West Indian Cliff Swallow. 



DESCRIPTION. 



Sp. Ch. Slightly smaller than the Cliff Swallow but very similar in coloration but lacks the dark 

 patch on the throat ; the chestnut of the throat s paler and the black of the head nearly surrounds the eye. 

 Length, 4.70 ; wing, 4.00 ; tail, 1.85 : bill, .27 ; tarsus, .40. Occurs on the Antilles, but two specimens were 

 taken on the Tortugas, Florida, March 22, 1800. I found this species breeding at Kingston, Jamaica, the 

 second week in February. The nests were placed inside the railroad station, one end of which was open and 

 the young birds flew in and out undisturbed by the coming and going of the trains. 



MINUS CAROLINENSIS GRISIFRONS Novo. 

 Key West Cat Bird. 



DESCRIPTION. 

 Sub Sp. Ch. Similar to the Cat Bird but differs in being smaller in size with a more slender bill, 

 generally darker in color, but with the forehead distinctly grayish, and with the primaries narrowly tipped 

 with ashy. Length, 8.60 ; stretch, 11.30; wing, 3.55 ; tail, 3.93; bill, .85; tarsus, 1.05. I have above des- 

 ignated a form of Cat Bird, of which I obtained a number of specimens, twenty or more, on Key West, in 

 November and December, 1870. The type ( original number 4281 ) is in the Museum of Comparative Zoology 

 where I have been permitted to examine it and other specimens, through the courtesy of Messrs. Brewster^
