Descriptions of two New Birds, of the genus Tyrannula. 273 



Summary. 



Species spending the summer, . . . . 112 

 Species resident all the year, .... 38 



Winter visitors, ....... 14 



Besides the birds given in the list, we have ascertained from 

 report that some other species visit us occasionally. Barton, in 

 a work entitled "-Fragments of the Natural History of Pennsyl- 

 vania," states that about the year 1760 large flocks of the Caro- 

 lina Parakeet, {Conurus Carolinensis, Linn.,) were seen in 

 Sherman's Valley, some twelve miles north of Carlisle. So un- 

 usual a circumstance caused great terror in the minds of the ig- 

 norant settlers, just as the appearance of the Bohemia Chatterer, 

 (Bombycilla garrula,) in various parts of the north of Europe, 

 occasions the dread, of some evil, which a visit from these birds 

 is supposed to portend. A small Rail, probably Ortygometra 

 Jamaicensis, Briss., has sometimes been killed in our vicinity, 

 though not of late years. The Common Crossbill, (Loxia cur- 

 virostra, Linn.,) is reported by persons living near the mountains, 

 to be frequently seen in winter. A small Ring Plover has also 

 been killed in our neighborhood. 



Descriptions of two species, supposed to be new, of the genus Ty- 

 rannula, (Swainson,) found in Cumberland County, Penn. 

 By Wm. M. and S. F. Baird, of Carlisle, Penn* 



For the first of the species hereafter described, we propose the 

 name of Tyrannula flaviveniris, the bright yellow color of the 

 lower parts constituting a striking feature. The other we have 

 named Tyrannula minima, it being the least of all our North 

 American Tyrannulse. 



The similarity in color and size between a number of our small 

 tyrant fly-catchers being very great, we have deemed it best to 

 send with the specimens of the two described, skins of T. Aca- 

 dica and T. Traillii, species which most nearly resemble them. 

 By a comparison of the four, the distinctive features of each will 

 at once be perceived.
