in trees. My friend Dr. E. Rey informs me that he has " received the eggs of this Eagle from 

 Hungary, Greece, Macedonia, Southern Russia, and Asia Minor. These eggs vary considerably 

 in coloration, grain, form, and size ; the average size of twenty-one eggs in my collection is 

 74 - 7 by 56 - 9 millimetres, the two largest measuring 82 - 5 by 57'0 and 76*5 by 60'0 millimetres, 

 the two smallest 70 - by 55"75 and 72*75 by 54-25 millimetres. In Hungary the eggs are 

 deposited from the 12th to the 30th of April, and the sitting usually consists of two, seldom 

 three eggs." 



The specimens figured are : — on the one Plate an adult female from India (spec, e in the 

 Norwich collection) and an adult male from Bulgaria, in my own collection; and on the second 

 Plate a young bird in the striated plumage from the Dobrudscha (spec, f in the Norwich collec- 

 tion) is figured with a young Aq. adalberti. The adult male described is the one figured, and 

 the young bird is also the Dobrudscha specimen figured on the second Plate. 



In the preparation of the above article I have examined the following specimens : —

Obs. Mr. Gurney has just sent to me for examination, from the Norwich Museum, one of Brehm's types of 

 A. adalberti (J, Aranjuez, 2nd of May, 1861), and I am thus enabled to state from actual observation 

 that it is that species in young plumage, and not A. navioides.
