eee | MiLtter, Abnormal Color Markings. 275 
There is probably another change required in our nomenclature 
of this genus; certainly so if, as some think, WZ. g. ellioti of 
SENNETT, 1892, is synonymous with his JZ, g. intermedia of 1879. 
Agriocharis ocellata is aterm which has been applied to the Hon- 
duras Turkey, which differs superspecifically from JZ. gallopavo in 
the lack of pectoral bristles, peculiar carunculation of the head, 
long sharp spurs of the male, and ocellation of some portions of 
the plumage, as set forth by CHapman, Bull. Am. Mus. Nat. Hist. 
Vili, 1896, p. 288. 
SOME ABNORMAL COLOR MARKINGS. 
BY GERRIT S. MILLER, JR. 
Many instances of albinism, melanism, and other abnormal 
color conditions in birds have been recorded,! but these records 
are for the most part concerned with cases in which large, con- 
spicuous, and indefinite areas of the plumage are affected. While 
such abnormalities are interesting they are greatly outweighed in 
importance by others, usually of a less noticeable character, in 
which the unusual markings are so arranged as to resemble normal 
color patterns. Suggestions of characters of related species are 
often to be found in these symmetrical markings, some of which 
might be regarded as the result of hybridism did not the well 
known hypothesis of atavism offer a more satisfactory explanation 
of their occurrence. I wish to call attention to a few of the more 
conspicuous among the many cases of this kind that have come to 
my notice.
