is the female of this bird, which is represented in a drawing 
brought by Mr. Crawfurd from Siam many years ago, both 
these specific names will have to give way to an older one. Dr. 
J. E. Gray having established his Phasianus crawfurdi (Griffith’s 
Cuvier’s An. Kingd. iii. p. 27) upon the faith of Mr. Crawfurd’s 
figure. 
We are happy to be able to announce that there is every proba¬ 
bility that the Vicomte B. Du Bus de Ghisignies will continue his 
‘ Esquisses Ornithologiques,’ the publication of which has been 
so long interrupted. On the other hand, we learn that M. de Sou- 
ance’s work on Parrots*, commenced in conjunction with the late 
Prince C. L. Bonaparte, has stopped at its 12th livraison, and 
that there is no probability of its continuance,—M. de Souance 
having parted with his fine collection of birds to M. E. Parzudaki, 
who now has the disposal of them. The same fate has befallen 
the corresponding work on Pigeons*. 
The Zoological Society of London have recently obtained 
specimens of the Buteo tachardus or African Buzzard, lately intro¬ 
duced into the European list by Mr. Bree (Birds of Europe, 
p. 97) upon the authority of Mr. J. H. Gurney. A pair of 
this species were received by the Society from Mogador some 
months ago. A pair of the Ruddy Shieldrake ( Casarca rutila) 
have bred in the Gardens for the first time this season, and 
reared four fine young birds. A solitary female of the South 
African White-faced Shieldrake ( Casarca cana) mated this spring 
with a male Common Shieldrake ( Tadorna vulpanser). The hy¬ 
brids are very curiously coloured. The same hen-bird has pre¬ 
viously bred twice with an Indian male of Casarca rutila. A 
valuable addition to the collection is shortly anticipated in the 
shape of some living examples of the Balceniceps now on their 
way down the Nile from Central Africa.
