INTRODUCED SPECIES. 



1. Tympanuchus americanus (Reich.). Prairie 

 Hen. 



According to Mr. Ned Dearborn ('98) a number were libera- 

 ted in Blue Mountain Park, Croydon, some years ago, and soon 

 disappeared. Mr. Dearborn believes that this will sufficiently 

 account for the fact that one was shot in Sanbornton in March, 

 1893, and that others were reported from Boscawen. 



2. JPhasianus colchicus LJnn. English Pheasant. 

 Belknap (1792) records that "the late Governor Wentworth 



brought several pairs of pheasants from England, and let them 

 fly in his woods, at Wolfeborough ; but they have not since been 

 seen." 



3. Passer domesticus (Linn.). House Sparrow. 

 Abundant as a resident about the large villages and cities. 



Among the country towns of central and northern New Hamp- 

 shire, it seems not to be increasing, and indeed barely holds 

 its own in many places among the White Mountain valleys. 

 Thus at Intervale, I have not observed any increase in numbers 

 during several years, though a single pair 01 two is annually 

 found nesting about the village.
