ing smaller, with the ground-color of a different shade of greenish- 
white. On calling Dr. Brewer’s attention to the discrepancy between 
his description and the set of eggs above described, he was led 
to re-examine the subject, and also to compare his egg with the set 
obtained by Mr. Bryant. As a result, he writes me that his egg 
corresponds exactly with those obtained at Mount Carmel. He fur- 
ther states that while they seem to resemble the eggs of B. cestiva> 
a comparison shows that while the spots on the eggs of the last- 
named species are “ olivaceous-brown,” those on the eggs of B. 
ccerulea are “ decidedly red-brown.” He also still further observes, 
“ In my egg and in Mr. Bryant’s the ground-color is very conspicu- 
ous, the spots sparse. In yours the spots are large and confluent, 
obscuring all the ground-color.” In the eggs collected at Penfield 
the blotches are probably exceptionally large and heavy, but the 
differences between these eggs and the others are not greater than 
occur not uncommonly between different sets of eggs in most spe- 
cies of birds that lay spotted eggs. There consequently appears to 
be no reason for doubting the authenticity of either of the sets of 
eggs here attributed to B. caemdea , which in two of the instances at 
least were identified by the capture of the parent bird. 
ADDITIONAL CASES OF ALBINISM AND MELANISM IN 
NORTH AMERICAN BIRDS. 
BY RUTHVEN DEANE. 
In Volume I (pp. 20 - 24) of this Bulletin I gave a list of sixty 
species which were affected by albinism, either partial or complete, 
and five species representing a melanistic phase of plumage. Since 
then I have been enabled to add twenty-seven species to the list of 
albinistic birds, and one case of melanism. 
In March, 1878, Mr. N. C. Brown of Portland, Me., saw a pair of 
pure white Mocking-Birds confined in a cage at Coosada, Ala. ; they 
had been taken from the nest, and retained the snowy whiteness of 
their plumage. Mr. George A. Boardman of St. Stephens, N. B., 
writes me that he has in his possession a specimen of the Mocking- 
Bird which is nearly white, which he shot at St. Augustine, Fla. 
Mr. C. J. Maynard has in his possession a Black-capped Titmouse
