A, exilipes and A. linaria, as in the case of the Crows, Corvus 
cornix and C. corone, or else the distinctive points of the un¬ 
streaked white rump and the unstreaked lower tail-coverts do 
not always hold good in A. exilipes ; or, again, they are of a 
distinct species intermediate between the two. I should 
hardly say “ intermediate,” for even at a hasty glance the 
very superior whiteness would proclaim them to be A. exilipes. 
A hybrid ought to be of really intermediate tone, but this bird 
is A. exilipes even to its small bill, and is quite as generally 
white. 
Eggs of the different Redpolls in collections must be very 
doubtful indeed when collected in Greenland or North-east 
America, for the collectors may have taken those of A. 
rostrata for A. hornemanni; and again eggs from Northern 
Europe referred to A. linaria may be those of A. exilipes. 
Except when the parent bird is sent with the eggs, they should 
be put out of collections, and fresh ones with the old bird ob¬ 
tained. I expect the egg of A. rostrata will prove to be the 
largest of the lot: the bird is so sturdy-looking.

54. Annals of the Natural-History Museum of Vienna. 
[Annalen des k. k. naturhistorischen Hofmuseums. Band i. Nr. 1, 
Jahresbericht fur 1885 von Dr. Franz Bitter von Hauer. Wien: 
1886.] 
The first part of this new periodical contains a report by 
Dr. v. Hauer on the newly erected Museum of Natural 
History in Vienna and its various departments. Besides 
Zoology, Botany, and Mineralogy in Austria, they have 
wisely located Anthropology in the same building. The 
Birds in the new museum remain under the charge of our 
excellent friend and correspondent Herr August v. Pelzeln. 
The general mounted collection of this class is stated to contain 
20,000 examples, besides which there is a separate series to 
illustrate the Ornis of the Austro-Hungarian empire, con¬ 
sisting of 621 specimens referable to 340 species.
