494 J. A. ALLEN ON BIRDS 



Certhiad^e. 



10. Certhia famttiaris Linn. 1 Brown Creeper. Noticed chiefly towards autumn, though 

 doubtless resident. 



Sittidje. 



11. SUta carolinemis Gmel. White-bellied Nuthatch. Common in the groves. 



Troglodytid.e. 



12. Troglodytes cedon Vieill. House Wren. Common about the settlements. 



13. Troglodytes hyemalis Vieill. Winter Wren. A Wren was seen several times in the 

 timber near Denison and Boonesboro, presumed to be this species. In every case it escaped 

 capture. 



MOTACILLID/E. 



14. Anthus ludoviciamis Licht. Tit Lark. Seen at New Jefferson, Sept. 18th to 22d, in 

 considerable numbers, running about in loose flocks over the furrows of new breakinga 

 Apparently had just arrived from its breeding quarters farther north j none having been 

 seen previously. 



Sylvicolid^e. 



15. Geothlypis trichas Cab. Maryland Yellow-throat. Not uncommon in bush patches and 

 in low grounds at the edges of timber. 



16. Icteria virens Bd. (7. viridis Bon.) Yellow-breasted Chat. Apparently rare. A 

 pair were obtained at Denison, and the species was once or twice noticed elsewhere. 



17. Helminthophaga peregrina Cab. Tennessee Warbler. Not uncommon about Denison, 

 in the low groves of bur and other oaks. 



18. Dendrceca ccerulea Baird. Blue Warbler. Quite common at Boonesboro, keeping 

 chiefly in the tops of the high trees, and was the only woodland Dendrceca observed there. 



19. Dendrceca cestiva Bd. Yellow Warbler. Occasionally seen about the osage orange and 

 white willow hedges, and the Cottonwood groves planted about the farms in the more settled 

 districts, and also about the borders of the timber. This and D. ccerulea were the only species 

 of the genus observed. 



20. Setophaga ruticilla Sw. Redstart. Perhaps breeds, but was not observed till the first 

 week in September, when it became quite common. At this time other species of the fam- 

 ily were now and then noticed, but under circumstances that prevented their capture. They 

 were probably species that breed beyond the limits of the State. 



Hirundinid.e. 



21. Hirundo horreorum Bart. Barn Swallow. Not generally common. Sometimes none 



highest family among birds; and that the Columbidai are, in " canadensis " and P. enucleator ; Falco " analum," and F. per- 



structural rank, decidedly above the highest forms of the egrinus ; Aquila " canadensis," and A. Chrysaetos ; Olus"Wil- 



rapacious birds. sonianus" and 0. vulgaris ; Brachjotus " Cassinii," and B. 



l I am unable to detect so great differences between average palustris, and in several other species in which the American 



specimens of C. americana Bon. from Massachusetts and representatives have been supposed by Bonaparte, or Cabanis, 



several skins of C. familiaris Linn, from Switzerland (in Mus. or some other authority, to be different from the European, 



of Comp. Zobl.), as a large series of Massachusetts specimens I am indebted to the Museum of Comparative Zoology for the 



usually present among themselves. The same may be said in opportunity of making comparisons of specimens in these and 



respect to Eremouhila " cornula" and E. alpestris ; Pinicola other cases from the two continents.
