PROTONOTARIA CITREA. Prothonotary Warbler. But one occurrence 

 in New England, male bird, obtained in October, at Calais, Me., by 

 G. A. Boardman. Accidental. A southern species. 



HELMINTHOPHAGA CHRTSOPTERA. Golden-winged Warbler. As stated 

 by Mr. H. A. Purdie, in the "American Naturalist," Vol. III. p. 497, 

 Massachusetts is probably about the northern limit of this species, and it 

 is a not uncommon summer visitor in that State, in-stead of a spring and 

 autumn migrant. He also mentions the discovery of the nest in West 

 Newton, by Mr. C. J. Maynard, thus confirming his belief that this 

 warbler nidified with us. 



In the same volume of the above magazine, pp. 5756, Mr. J. A. Allen 

 thus describes the nest found by Mr. Maynard : 



The nest was placed " on the ground, in a tract of coarse weeds and 

 ferns, near a swampy thicket, and but a few rods from a public highway. 

 It was placed entirely above the surface of the ground, and the birds 

 seem to have made no special effort to conceal it. It was composed ex- 

 ternally of dried oak-leaves and the bark of the grape-vine, and rather 

 roughly lined with fine grass and a few horse-hairs. He says it is large 

 for the size of the bird, and somewhat reminds one of the nest of the 

 Maryland Yellow Throat. It is a little smaller at the top, where the 

 internal diameter is less than two .inches, while in the middle it is two and 

 a quarter. The eggs were five in number, including a Cow Bunting's 

 egg that these watchful parasites had introduced." 



These eggs are described as varying from 66.100th inch in length by 

 55.100th inch in breadth to 66.100th inch by 53.100th inch, and being 

 more or less spotted and blotched with brown, over a white ground 

 color. 



HELMINTHOPHAGA CELATA. Orange Crowned Warbler. Accidental. 

 One obtained at Springfield, Mass. ; others seen, May, 1863, by J. A. 

 Allen. A western species. ' 



SEIURUS LUDOVICIANUS. Large-billed Water Thrush. Very rare, if 

 not accidental, summer visitor. One taken at Norway, Me., May, 

 1865, by Irving Frost; one at Waterville, Me., 1865, Professor 

 C. E. Hamlin; one on Mount Tom, Mass., April 28, 1869, by J. A. 

 Allen. 



DENDROICA CJERULEA. Blue Warbler. Perhaps an accidental summer 

 visitor to extreme southern portions of New England. No recent in- 

 stances on record of its occurrence. 



DFNDROICA MACULOSA. Black and Yellow Warbler. The following 

 description of a nest and eggs of this species is kindly furnished me by
