essentially a southern one; but still it has been found at Washin<ftoii, 

 D. C, (Coues and Prentiss, Smiths. Hep. for 1861, p. 408; Baird, 

 llev. Am. Birds, p. 20!)), and at Cleveland, Ohio, (I.e.). It is more 

 abundant in some parts of the State than is generally supposed. I 

 have seen several in one day in the streets of Columbia. It winters 

 very far south. 



43. D. vlrejis. Black-throated Green Warbler. 



44. D. ccei-ukscens. Black-throated Blue Warbler. 



45. D. Blackburnice. Blackburnian Warbler. 



46. D. castanea. Bay-breasted AVarbler. 



47. D. pennsylvanica. Chestnut-sided Warbler. 



48. D. striata. Black-poll Warbler. 



49. I), coerulea. Carulean Warbler. 



50. D. maculosa. Black-and-j'ellow Warbler. 



51. D. discolor. Prairie Warbler. 



The foregoing nine species are all migrants, passing through chiefly 

 in April and Oct. — D. slria,'a being rather the latest. D. coerulea is the 

 rarest; D. discolor probably next most so; the other seven are common. 



52. Seiiirus novehurucensis. Water Wagtail. Not ab. ; chiefly 

 migr. Some probably breed. 



53. S. aurocapillus. Golden-crowned Wagtail. Com.; migr.; 

 some doubtless breed. 



54. .S'. ludooiciaims. Large-billed Wagtail. Rare; migr.; some 

 doubtless breed. Dr. Prentiss and I found it to be quite common at 

 certain seasons about Washington, D. C. (Smiths. Rep. for 1861, p. 

 407.) It is recorded by Mr. Lawrence from New York (Ann. Lye. 

 Nat. Hist., N. Y., VIII, 1866, p. 284), and by Prof. Ba-'-d <Vom Penn- 

 .sylvania and Michigan. (Rev. Am. Birds, p. 217.) 



55. Oporoniis agilis. Connecticut AVarbler. 



56. O. formosus. Kentucky Warbler. 



These two species are rare migrants. I have found furmosus in 

 Kansas, in May. This is, I believe, its most western United States 

 record. Both species proceed as far north, at least, as Southern New 

 England. 



57. Geotldjipis trichas. Maryland Yellow Throat. Com.; sum.; 

 most numerous during its migr., in Apr. and Oct. 



58. G. Philadelphia. Mourning AVarbler. Very rare; migr. 



59. Icteria viridis. Yellow-breasted Chat. Com. ; sum.; but most 

 numerous during its migr. 



60. Myindioctes witratus. Hooded Warbler. Rare; migr.; some
