Progne subis. PURPLE MARTIN. Several colonies were observed 

 about Mountain Lake Park, and a colony at Frostburg in the north- 

 western part of Allegany county. 



Petroclielidon lunifrons. CLIFF SWALLOW. This familiar species 

 noted in the vicinity of nearly every farmhouse throughout the higher 

 part of Garrett county. It was common near Finzel, Grantsville, Bit- 

 tinger and Mountain Lake Park. Great numbers of their nests were 

 seen beneath the overhanging portions of the old-fashioned barns. 



Hirundo erythrogaster. BARN SWALLOW. Generally distributed 

 and common throughout the region, being noted, usually in large 

 numbers, at every place visited, excepting Oldtown. They nested 

 in nearly every barn through the country. In the vicinity of Grants- 

 ville, June 22-27, great numbers of young birds just from the nest 

 were observed. 



Clivicola riparia. BANK SWALLOW. A single bird was seen at 

 Little Orleans on July 24. 



Ampelis cedrorum. CEDAR WAXWING. Noted in abundance at 

 Finzel, Grantsville, Bittinger, Mountain Lake Park and Swanton. 

 A nest found at the latter place on July 19 contained three eggs. A 

 few individuals were also seen at Oldtown. 



Vireo olivaceus. RED-EYED VIREO. This species was very abund- 

 ant and generally distributed throughout the region, being observed at 

 all the places visited. 



Vireo flarifrons. YELLOW-THROATED VIREO. A number were 

 observed in thickets bordering the Potomac at Oldtown. 



Vireo solitarius. SOLITARY VIREO. This species was fairly com- 

 mon in hemlock and mixed woods near Finzel, Grantsville and Bit- 

 tinger. I took a specimen near Kearney, a few miles southeast of 

 Mountain Lake Park, and the song of one was heard at Swanton. I 

 also saAv several on Dans Mountain. Specimens taken at Finzel and 

 near Kearney show some slight approach in measurements and color 

 of upper parts to V. s. alticola, but, on the whole, seem much nearer 

 to the typical form. 



Minotilta varia. BLACK AND WHITE WARBLER. Common and 

 quite generally distributed. It was seen at all the places visited ex-
