22 QUARTERLY BULLETIN. 



M nine, the head is pure white, with the exception of the yellow 

 superciliary stripe which remains and causes a marked contrast. 



The most interesting and striking cases of albinism are those 

 among the Icteridce and Corvidce, and how many times have I as- 

 tonished disinterested persons by referring to a white Black- 

 bird or a white Crow, and to such persons it must indeed seem 

 very absurd to prefix " white" before Blackbird, and also be- 

 fore Crow, for how common the comparison is, " as black as 

 a Crow," but as previously remarked, this family are as likely 

 to be represented as any others. Several examples of S. magna 

 have been noted. D. oryzivorus has been taken in this plumage, as 

 lias also M. pecoris, A. pkaeniceus, X. icterocephalus, Q. purpureus, 

 and C. cristatus. This last was a beautiful specimen of a pe- 

 culiar character of albinism, the bright plumage being modi- 

 fied as though a white veil had been thrown over it, yet all the 

 natural markings of the birds could be plainly seen. 



I am induced to think that among the Tyrannidce but few ex- 

 amples have been detected, as T. Carolinensis is the only exam- 

 ple I have ever heard of. This specimen was in the collection 

 of Mr. James Booth at Niagara Falls. The bird. has a stained 

 or creamy plumage, but the most interesting point is that the 

 flame-colored patch on the crown remains ; a case similar to A. 

 linaria. C. auratus is the only example among the Picidce that 

 has come under m}' notice. I have an extremely light colored 

 specimen of S. varius, which I collected at the Urabagog Lakes, 

 but am inclined to think that this was caused by old age. 



Among the Strigidce a fine specimen of S. nebulosum is in the 

 natural history museum at Niagara Falls. The. only one 

 among the Falconidce, on my list, is that of B. borealis, a mag- 

 nificent example, pure white, taken on the Hoboken marshes, 

 N. J. Among the Columhidce, E. migratorius is noted. Frequent 

 occurrences among the Tetraonidce are illustrated in C. cupido, 

 B. umbellus, and O. Virginia?ius, though occasional examples are 

 found in 0. pictus and L. Californicus. A beautiful specimen of 

 B. umbellus was recently taken in West Bridge water, Mass., its 

 plumage being white as the driven snow. 



I have seen 0. Virginianus having the veiled appearance as 

 described in the Blue Jay. 



An albino, 0. fulvus var. virginicus, was shot on Cape Cod, in 

 September, 1875. This is the only instance which has come to 

 my knowledge of albinism occurring in any of our Plovers or
