Notes on Mr. R. B. Sharpens Catalogue of Aocipitres. 579 



Meagre as the above notes certainly are^ still they will, I 

 trust, in some measure supplement the paper by Taezanowski 

 published in the ' Journal fiir Ornithologie ' 1870, and also 

 the papers of Salvin, Tristram, and other workers in the field 

 of Algerian ornithology, which have from time to time ap- 

 peared in the present Journal, In my opinion much good 

 work remains to be done in the Aures mountains, and also in 

 the country round Biskra. Travelling is comparatively easy, 

 and, in spite of sundry dark rumours to the contrary, the 

 country is safe, with due precautions. So easily accessible 

 as Algeria is from England, the wonder is that so few of our 

 ornithologists have devoted their energies to a study of its 

 bird-life, which exists in such great variety and under such 

 varied and peculiar conditions. 



XLII. — Notes on a ' Catalogue of the Accipitres in the 

 British Museum' by R. Bowdler Sharpe (1874). By J.

In my last paper, at p. 438, I referred to a female speci- 

 men of Falco barbarus in the British Museum as determined 

 by Mr. Howard Saunders, who has since informed me that 

 its sex was ascertained by a careful naturalist at Granada, 

 also that he agrees with my identification of the species, and 

 that the label " Falco communis " was not attached to the 

 skin by him. 



There remains but one group of Falcons for our con- 

 sideration, the subgenus Hierofalco, which, as I have already 

 withdrawn from it the Saker and Mexican Falcons included 

 in it by Mr. Sharpe*, I shall treat as consisting of the 

 Arctic Falcons only. 



One of these, the dark Falcon of Labrador, which was 

 obtained in that country by Audubon, who figured it under 

 the name of Falco labradora f, is referred to in Mr. Sharpens
