of these feathers, and perhaps on the mantle generally, giving 

 the appearance described as that of an old male in Dresser's 

 •^ Birds of Europe/ vol. vi, p. 103. 



Figure 4 on pi. 54 of Schlegel and Susemihl's ' Vogel 

 Eui'opa's ' represents a specimen so grey and so closely re- 

 sembling in colour the adult plumage of H. concolor that* I 

 should not hesitate to refer it to that species were it not that 

 the wings, as there represented, are scarcely so long as those 

 of //. concolor ; and the plate, being taken from a drawing by 

 Mr. Wolf, is not likely to be inaccurate in that respect. 

 Dr. Bureau has been so good as to inform me that the 

 original of this figure is the specimen thus described by 

 Professor Schlegel in his ' Museum des Pays-Bas,' vol. i. 

 Falcones, p. 25 : " Falco eleanoroi, femelle adulte, Grece, par 

 M. Schulze 'en 1843. Variete a teinte couleur de schiste.'' 

 The authors of ' Les Richesses Ornithologiques du Midi de 

 la France/ at p. 523 of that work, quote a description fur- 

 nished to them by the late Jules Verreaux of a very similar 

 specimen; but as that ornithologist held the erroneous opinion 

 that H. concolor is not specifically distinct from H. eleanora, 

 it is possible that the bird he described was in reality an 

 example of H. concolor. 



Mr. Sharpe's volume does not contain any reference to the 

 geographical distribution of H. eleanora ; but a summary of 

 what is known on this head will be found in Dresser's ' Birds 

 of Europe,' vol. vi. p. 104. It is, however, there stated that 

 this species does not occur in North-eastern Africa, which is 

 not quite correct, as the plate of " Falco gracilis " of Brelim, 

 to which I have already referred, and which unquestionably 

 represents the first plumage of H. eleanorce, is inscribed '' In 

 deserto prope Cairo, Sept. 1851 " *. I may also mention as 

 an addition to the localities given for H. eleanoroi in Mr. 

 Dresser's work, that Mr. Edward Newton obtained a speci- 

 men in immature plumage in the island of Mauritius, after 

 stormy weather in the month of December. 



There remains but one Old- World species of the genus 



* This fact Las been already referred to in the ' Rambles of a Natu- 

 ralist,' by J. H. Gurney, Jun., p. 122.
