England alive, and is now in the gardens of the Zoological 

 Society of London. 



[Mr. W. C. Hewitson has, with his usual kindness, drawn 

 the accompanying Plate, in which what we believe to be the first 

 well-identified eggs of Falco lanarius, Schlegel, are depicted. 



Fig. 1 represents one of the eggs obtained, April 3rd, 1863, 

 from the Pyramid of Dashoor, along with the female now alive 

 in the Zoological Society^s Gardens. 



Fig. 2 represents one of the eggs obtained from the small 

 Pyramid of Ghizeh, 26th of March, 1863. 



We may remark that we believe that Egyptian specimens of 

 Falco sacer are not distinguishable from the European form 

 which has been termed Falco feldeggii. On the other hand, 

 Abyssinian examples {Falco tanypterus, Licht.) are decidedly 

 smaller and darker in colouring. — Ed.] 



XV. — Note on Astur griseiceps, Schlegel. By A. R. Wallace, 



F.Z.S., &c. 



(Plate V.) 



This beautiful Hawk, which has been recently described by 

 Dr. Schlegel (Museum d'Histoire Nat. des Pays-Bas, " Astures," 

 p. 24), presents us with another case of the island of Celebes 

 possessing its own restricted species. The well-known Astur 

 trivirgatus of Temminck ranges over Sumatra, Java, Borneo, the 

 Philippine Islands, and, with but slight modification, over the 

 whole of India and Ceylon ; but the moment we pass over into 

 Celebes, we find it represented by the allied yet perfectly distinct 

 species now figured. 



The specimens of Astur griseiceps in the Leyden Museum are 

 from the northern part of the island, where I also found it. I 

 likewise obtained one specimen of this species in the south, 

 near Macassar. It seems, however, to be a rare bird, as the 

 Leyden Museum contains only three specimens, obtained from 

 Forsten, who collected for nearly two years in North Celebes ; 

 and I myself got the same number during about nine months' 

 assiduous collecting in various parts of the island.
