of Madagascar and the adjacent Islands. 445 



The two Falcons from Madagascar in tlic Museum of the 

 Jardin des Plantes, under the name of F. radama, are, like the 

 Joanna example just mentioned, also in immature plumage, with 

 their sexes unrecorded ; but M. Verreaux now agrees with me in 

 regarding them as young females of F. minor. 



2. Hypotriorchis ELEONORiE (Gen^). Eleonora^s Falcon. 

 (Plate XVI.) 



The Norwich Museum possesses the example of a Falcon 

 formerly recorded in this Jounial (Ibis, 1862, p. 267), under the 

 name of Falco radama, as having been taken at sea off the east 

 coast of ]\Iadagascar. I have the testimony of Mr. Edward 

 Newton that this specimen closely resembles the example pre- 

 served in the Museum of St. Denis, the capital of Reunion, and 

 described, under the name of F. radama, by M. Maillard in his 

 work on that island*, as having been obtained there, which tes- 

 timony is also confirmed by a comparison of the description with 

 the Norwich birdf. But further comparison also shows that this 

 last, which is the subject of the accompanying plate (Plate XVI.) 

 by Mr. Wolf, agrees completely with a specimen of H. eleunorie 

 in a similar stage of plumage from the Greek archipelago ; and it 

 therefore appears that the species last mentioned extends its 

 range to Madagascar, and occasionally also to Reunion, a fact 

 of which MM. Schlegel and Pollen do not seem to be aware. 



3. Hypotriorchis concolor (Temm.). Grey Hobby. 



MM. Schlegel and Pollen {op. cit. p. 31) record two Mada- 

 gascar examples of this species preserved in the Museum of the 

 Jardin des Plantes, a third in that of Leyden {op. cit. p. 165), 

 and two others in the possession of Messrs. A. and E. Newton 

 which were taken at sea off the coast of Madagascar, and are 

 both in immature plumage, as is also a third specimen in the 

 collection of those gentlemen, which was procured in Mada- 

 gascar by the late Mr. Gerrard. The bird in this plumage is

 pp. 103, 104. 



t Since these remarks were written I have been informed by M. Ver- 

 reaux that the Curator of the Reunion Museum has recently visited that 

 of Paris, and has expressed his opinion that the Falcon in the former much 

 resembles the two Madagascar specimens in the latter, which I believe to 

 be immature females of F. minor, as already stated.
