Birds' Eyr/s in the British Museum. 519 



clutch of four eggSj though here separately catalogued 

 (see ' Zoologist/ 1875, pp. 4654, 4658). Five eggs 

 from near Berlin, taken by Dr. Holland and marked 

 by him '' cyaneus,'''' are here catalogued under 

 ^' pijgargus.'''' 



P. 239. C macrurus (S. G. Gmel.). Apparently the eggs 

 ascribed to this species from the Seebohm collection 

 are so designated solely because they are spotted and 

 blotched with brownish markings, though the series 

 includes specimens marked by the collectors as cijaneus 

 and pygargus. In the case of birds like the Harriers, 

 whose eggs so nearly resemble one another, this pro- 

 ceeding is quite unjustifiable. 



P. 239. C. (BTuginosus (L.). The locality ''near Oxford, 

 July," givcH. with an egg presented by Mr. H. K. 

 Swann, has been known to be unreliable for nearly 

 twenty years. The statement was withdrawn in the 

 'Zoologist,' 1894, pp. 268, 304, etc., but still remains 

 uncorrected in the ' Catalogue.' 



P. 254. Buteo desertorum (Daud.). Under this head are 

 grouped the eggs of two distinct species : three clutches 

 of the eastern form of the Common Buzzard, B. buteo 

 desertorum, and eggs from three sources of the North 

 African race of the Long-legged Buzzard, B. ferox 

 cirtensis Lev. 



P. 264. Aquila heUaca Sar. The e^^g from Mt. Edough, 

 nr. Bone, Algeria, may possibly be that of A. rapax 

 belisarius, which undoubtedly breeds there. The evi- 

 dence of the breeding of A. heliaca and A. adalberti in 

 N. Africa is very unsatisfactory. 



P. 268. Aquila maculata Gm. The series of eggs catalogued 

 under this heading is in some confusion, and obviously 

 includes eggs of both species of Spotted Eagle. Thus 

 a clutch of two eggs from Parnassus, taken 23 April, 

 1875, by Kriiper, and marked by him " A. ncevia," is 

 evidently the Lesser Spotted Eagle. The eggs from 

 Tunisia should also be queried in the absence of any 

 proof as to which form breeds there.
