essentially a soutlieru one ; but still it bus been found at Washington, 

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

 Rev. Am. Birds, p. 209), 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. virens. Black-throated Green Warbler. 



44. D. c(£rule.<icens. Black-thi'oated Blue Warbler. 



45. D. Blackburnke. Blackburnian Warbler. 



46. D. castanea. Bay-breasted Warbler. 



47. D. pennsylvanica. Chestnut-sided Warbler. 



48. D. shiala. Black-poll Warbler. 

 41). D. ciEfulra. Coeruleau Warbler. 



50. D. maculosa. Black-and-yellow Warbler. 



51. D. discolor. Prairie Warbler. 



The foregoing nine species are all migrants, passing through chiefly 

 in April and Oct.— Z). striata being rather the latest. D. coerulea is the 

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



52. Seinrti^ novehoraccnsis. Water Wagtail. Not ab. ; chiefly 

 migr. Some probably breed. 



53. S. aurocaptllu:<. Golden-crowned AVagtail. Com.; migr.; 

 some doubtless breed. 



54. >S'. ludovicianus. Lai'ge-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. Lawi-euce from New York (Ann. Lye. 

 Nat. Hist., N. Y., VIH, 1866, p. 284), and by Prof Baird from Penn- 

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



55. Oporornis agilis. Connecticut Warbler. 

 66. 0. formosus. Kentucky Warbler. 



These two species are rare migrants. I have found formosus 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. Geoihli/pis trichas. Maryland Yellow Throat. Com.; sum.; 

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



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



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

 numerous during its migr. 



60. Myiodioctes mitratus. Hooded Warbler. Rare; migr.; some
