NUTTALL ORNITHOLOGICAL CLUR. 21 



in some families than others, and I can now recall some fifty or 

 sixty different species in which it is represented. 



Among the Turdidce, the Robin (T. migrator ius), is the only 

 species 1 have seen in the albino state, and in my experience is 

 the most common example among our. birds, though we rarely 

 hear of pure white specimens, and out of some twenty I have 

 seen, there were not an}* two that resembled each other. 



Among the Saxicolidce, I have seen the Bluebird (S. sialia) 

 represented, the specimen being of a light yellowish cast, 

 though traces of its normal plumage could readily be discerned* 



Representatives among the Sylvicolidce, I have seen in lim- 

 ited numbers for so large a family, the examples being P. Amer- 

 icana, a beautifully marked specimen among the collection of 

 the Smithsonian Institution. D. castanea, a small'portion of the 

 forehead being white, and extending over half of the upper man- 

 dible. D.coronata has been taken in partial state, and S.ruticilla. 

 This later species I shot some years ago, and it presents a curious 

 mixture of coloration. The black head and breast is mottled 

 with white, the black dorsum is replaced by bright orange, with 

 a few blackish feathers intermixed, while the belly and crissum 

 are much more strongly marked with orange than in a typical 

 specimen. I was attracted at some distance by this peculiar 

 plumage, and like all abnormal birds it was unusually shy. 



Albinism among the Hirundinidce is generally pure white or 

 of a strong yellowish cast, and I cannot recall of having seen 

 or heard of a specimen in only a partial state. I have seen 

 specimens of H. horreorum, T. bicolor, C. riparia, P. lunifrons, 

 and P. purpurea, in this white dress. Ampelis cedrorum has 

 been taken in some striking stages of plumage, the crest, 

 wax appendages on the wings, and the yellow tips of the tail 

 feathers retaining* color, while the rest of the body bore a 

 bleached out appearance. 



Doubtless the FringiUidce are represented more largely than 

 any family, though but eleven species have 1 come under my no- 

 tice, Passer domeslkus being the only one pure white. A speci- 

 men of A. linaria was recently captured, whose plumage was 

 white, with the exception of the crimson patch on the crown. 

 The other examples are P. gramineus, M. melodia, J. Orcgonus, 

 S. monticola, S. socialis, S. pusilla, Z. albicollis, and P. illiaca — all 

 these presenting a mottled plumage. In a specimen of Z. albi- 

 collis, kindly presented to me by Mr. N. G. Brown, of Portland,
