A. exilipes and A. linaria, as in the case of the Crows, Co7'Vus 

 comix 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 tM^o. I should 

 hardly say " intermediate," for even at a hasty glance the 

 very superior whiteness would proclaim them to be^. 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.

 [Annalen des k. k. naturhistorisclien Hofmuseums. Band i. Nr. 1, 

 Jahresbericht fiir 1885 von Dr. Franz Eitter von Hauer. Wien : 



1886.] 



The first part of this new periodical contains a report by 

 Dr. V. Hauer on the newly erected IMuseum of Natural 

 History in Vienna and its various departments. Besides 

 Zoology, Botany, and IViineralogy 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.
