446 Mr. J. H. Gurney on the Birds-of-prey 



figured by MM. Schlegel and Pollen {op. cit. pi. xii. fig. 1) ; but 

 among the representations of it in its adult state which have been 

 published I may mention that in Gould's ' Birds of Europe' and 

 that (with the egg) in Ilemprich and Ehrenberg's ' Symbolae 

 Physicse ' (pi. 19) under the name of Falco schistaceus. 



The Falcon from the Zambesi in the Norwich Museum which 

 I formerly described (Ibis, 1866, p. 127) as an immature speci- 

 men of H. concolor, appears on further examination not to belong 

 to that species, but to be a young male of Erythropus amurensis 

 (Ibis, 1868, pp. 41-43). 



4. DissoDECTEs zoNiVENTRis (Pctcrs). Petcrs's Falcon. 

 MM. Schlegel and Pollen mention {op. cit. p. 165) that the 



Leydeu Museum has recently acquired two examples of this 

 species, hitherto known only by a single specimen which was 

 obtained by Dr. Peters at St. Augustine's Bay in Madagascar, 

 and deposited in the Berlin Museum, but has since been 

 unfortunately lost^ though happily a coloured drawing* of it is 

 preserved, from which was taken the description contained in 

 Dr. Hartlaub's ' Ornithologischer Beitrag zur Fauna Mada- 

 gascar's' (p. 17). Dr. Hartlaub there remarks that in form 

 and colouring this bird forcibly reminds ns of the genus Avicida ; 

 but it is a genuine Dissodectes, to which genus it was assigned 

 by Mr. Sclater (Ibis, 1864, p. 308), with comparatively short 

 wings and a double-toothed upper mandible. Both the speci- 

 mens at Leyden, which by Prof. Schlegel's kindness I have 

 examined, are males, and were obtained in north-eastern Mada- 

 gascar by M. Van Dam. They agree exactly with Dr. Peters's 

 drawing except that, not being fully adult, the markings are 

 rather less distinct and the white spaces between them rather 

 dusky. The wing from the carpal joint measures 8*75, the tail 

 5'5, tarsus 1"5, and the middle toe, without the claw, 1 inch. 



5. TiNNUNCULUS NEWTONi, Gumcy. Newton's Kestrel. 

 This species appears to be the only Kestrel hitherto found in 



Madagascar, and is stated by MM. Schlegel and Pollen {op. cit. 



* [We have to mention with pleasure our indebtedness to Dr. Peters, 

 who at our request some time since most obligingly lent this drawing to 

 us. From it an excellent copy in facsimile was made by Mr. Smit, and 

 this has been at our contributor's disposal for the present paper. — Eb.]
