became the possessor of the specimen and kept it for several 
months, when the bird grew sick and died. The disease affected 
the skin and feathers to such an extent that it was unfit for 
preparation; although the specimen was for some time a matter 
of public curiosity. An instance of total albinism occurred some 
years ago in Lehigh County, Penna., where the bird was kept 
for a number of years as a bar-room pet. Another example oc- 
curred during the winter of 1873-74, in Montgomery County, 
Penn., where the specimen was secured while a hunting party 
happened upon a rookery during the night. A great many birds 
were shot and amongst them the albino. 
Several instances of total and partial albinism in 7urdus 
migratorius, have come under my observation in Pennsylvania. 
In several of the supposed cases of total albinism, a pale yellow- 
ish tint could be discovered upon the tips of the feathers over the 
breast and sides, which was replaced upon the back by a slight 
grayish or ashy shade ; although at a short distance they appeared 
perfectly white. 
female Hirundo horreorum was secured in the summer of 
1875, near Reading, Penna., which had patches of white upon 
either side, extending upwards and forwards to the base of the 
wing. The left wing also contained several white secondaries. 
From the spring of 1874, to the summer of 1877, four differ- 
ent specimens of Passer domesticus have come under my obser- 
vation which were partly white. The markings were irregular 
and included parts of the wings, rump and abdomen, or as in one 
instance, the tail feathers. One specimen of total albinism was 
seen in the streets of Reading for several months, when all of a 
sudden it disappeared from its usual haunts, no doubt being se- 
cured by a collector for the adornment of his cabinet. 
There is at present in a collection in Reading, an example of a 
nearly white Buteo borealis. The only defect consists of pale 
yellowish brown transverse markings near the tip of the tail 
feathers. There are visible upon close examination, delicate ashy 
tinted median lines in the feathers of the head, neck and back. | 
In all other respects the bird is certainly interesting. 
Partial albinism in Age/eus phæniceus is not of uncommon oc- , 
currence, when one is on the lookout for such specimens. In the 
collection before referred to,are several males with the deep red and 
yellow colors upon the wings, but which in other respects appear 
very different. The color at a short distance appears yellowish- 
brown, which upon closer inspection, results from that color tip- 
ping all the feathers overthe body. In another specimen, the red 
of the wing is replaced by deep orange. . 
Frequent specimens of Sturnella magna occur which would 
readily be taken for neglecta, were the observer ignorant of the 
locality. They resemble the latter very closely, but do not have 
the characteristic note of the western variety. There are more
