The eggs, six in number, were a clear white with many spots and 
blotches of light reddish brown distributed over the surface, con- 
fluent at the large end to form a wreath. They were also character- 
ized by a few light lavender marks and a few almost black lines and 
spots. 
Average dimensions .698” X .50”. 
The author is aware that the observations here recorded do not 
appear to harmonize well with the accounts of J. W. Banks and 
others of the nesting habits of the Cape May Warbler. It seems 
probable that this pair of birds were not typical in their choice of a 
nesting site. It is also probable that nest construction varies 
considerably in different localities as is often the case with other 
warblers. Notwithstanding these variations it is hoped that the 
details here given may be of service in the further study of this 
very interesting warbler. 
THE STATUS OF “LARUS THAVERI, THAYER’S GULL.” 
BY JONATHAN DWIGHT, M.D. 
Plate XV. 
Apout two years ago a new Arctic Gull was described as “Larus 
thayeri”” on the strength of a few birds obtained in Ellesmere Land 
(see Brooks, Bull. M. C. Z. LIX, No. 5, Sept. 1915, pp. 373-375). 
Recently, thanks to the courtesy of Mr. P. A. Taverner, of the 
Victoria Memorial Museum of the Canadian Geological Survey, 
I have had opportunity of comparing his fine series of Arctic Gulls 
with the type and others of thayeri loaned me by Mr. O. Bangs of 
the Museum of Comparative Zodlogy. Other specimens in the 
American Museum of Natural History and in my own collection 
bring the series examined up to twenty-five and these compared 
with a much larger series of the Herring Gull (Larus argentatus) 
demonstrate that the supposed new species is nothing more than a
