15G BULLETIN OF THE 



7. Wilsonia pusilla. Abundant in the willows along the streams. Saw 

 sometimes a dozen pairs during a morning's hunt. 



The preceding two species were the only Sylvicolidce seen. Geothlypis 

 Philadelphia, var. Macgulivrayi, however, is doubtless more or less frequent, as 

 it was common everywhere in the mountains to the eastward. 



HIRUNDINIDJE. 



8. Hirundo horreorum. More or less generally distributed throughout 

 the Park, but most numerous in the vicinity of Fairplay. 



9. Hirundo bicolor. Generally distributed, breeding in woodpecker's 

 holes. 



10. Hirundo lunifrons. Common at intervals throughout the Park. 

 Found a large colony at Fairplay, nesting under the eaves of buildings. 

 Thirty-eight nests were observed on one house, all within a space of twenty 

 feet. 



VIREONIDJE. 



11. Vireo gilvus. Rather common. 



12. Vireo solitarius, var. plumbeus. One shot and others seen at 

 Fairplay. 



ALAUDIDJE. 



13. Eremophila alpestris. Common throughout the Park. 



FRINGILLIDiE. 



14. Chrysomitris sp. ? A species of Cltrysomitris was frequently noticed 

 at a distance. C. pinus occurs throughout the adjoining region, and doubt- 

 less this was the species observed in the Park. C. tristis was not met with 

 after entering the mountains. 



15. Carpodacus purpureus. A few pairs were seen at Fairplay. 



16. Passerculus savanna. Common along the streams, but far more 

 numerous near the mountains. Very numerous at our camp on Jefferson 

 Creek (July 14), where we found nests with eggs and with young. The 

 numerous specimens obtained here presented great variations in size and 

 in markings, but no decided general differences from summer specimens 

 from Massachusetts.* 



17. Pocecetes gramineus. More or less common. 



18. Chondestes grammaca. Not numerous. 



1 9. Zonotrichia leucophrys. Exceedingly numerous at Fairplay, 

 and everywhere more or less common. The large number of specimens 

 obtained were, with few exceptions, typically of the leucophrys type.

 middle and western portions of North America, see Bull. Mus. Comp. Zool., Vol. II, pp.
