448 Ml-. J. H. Gurney on the Birds-of-prey 



the former series of this Journal (Ibis, 1864, p. 298, pi. vii.). 

 The sex of these specimens was not ascertained ; but, from the 

 circumstance that one of them is sHghtly larger than the other — 

 the dimensions of both were recorded [he. cit.) — it may be sup- 

 posed that they were a pair. If, however, the view of MM. 

 Schlegel and Pollen as to the specific identity of A. francisca 

 and A. madagaseariensis be correct, the disparity in size between 

 the two sexes is much greater than that which exists between 

 the two Comoro specimens, which must therefore in that case be 

 both males. The authors just mentioned, in their work, give 

 (pi. xiv.) three figures of A. madagaseariensis, apparently repre- 

 senting two females, one adult the other immature, and an adult 

 male with transverse abdominal bands. 



10, AcciPiTER LANTZi, Verrcaux. Lantz's Sparrow-Hawk. 



I have had the pleasure of examining an immature male spe- 

 cimen in the Museum at Paris of this the most normal of the 

 Madagascar Sparrow-Hawks, which was originally described and 

 figured by M. Jules Verrcaux (Rev. Zool. 1866, pp. 353-355, 

 pi. xviii.), and since by MM. Schlegel and Pollen {op. eit. p. 35, 

 pi. xiii.). It appears to have hitherto been found in Madagas- 

 car only. 



11, AcciPiTER MORELi (Pollcu). MorcPs Sparrow-Hawk. 

 Of this Hawk, which was obtained by M. Lantz on the east 



coast of Madagascar, the Museum of the Jardin des Plantes 

 contains two specimens — an adult male from Madagascar, and an 

 immature female from Mayotte. It is figured by MM. Schlegel 

 and Pollen (pi. xiii. fig. 3). M. Jules Verrcaux informs me 

 that he considers the Nisus polleni of M. Grandidier (Rev. Zool. 

 1867, p. 85) to be identical with A. moreli. 



12, AcciPiTER BRUTUS (Pollcn). Mayotte Sparrow-Hawk. 

 This small species appears to be confined to the island of 



Mayotte ; the only examples of it that I have seen are, one in 

 the Norwich Museum, received in exchange from the Museum 

 at Leyden, and one in the Museum of the Jardin des Plantes. 

 It is described and figured by MM. Schlegel and Pollen [op. cit. 

 p, 38, pi, xii. fig. 2).
