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 D. wsliva, 

 a comparison shows that while the spots on the eggs of the last- 

 named species are " olivaceous-brown," those on the eggs of D. 

 cceruha 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 heav}', 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 D. caeruha, 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
