476 Mr. J. H. Gumey^s Notes on 



deration of the remaining Buteonine genera, amongst which 

 it will^ I think, he convenient to refer first to that very in- 

 teresting newly discovered form which has received from its 

 first descriher, Mr. Ridgway, the appellation of Onychotes 

 gruberi. 



As this species has heen accidentally omitted from the index 

 to Mr. Sharpens volume, I may mention that his account of 

 it will be found at page 158 of his Catalogue ; and I may add 

 that a fuller description, with woodcuts of the type specimen 

 and of some of its details, is given at pages 252 to 254 of 

 vol. iii. of the ' History of North-American Land-Birds,' by 

 Messrs. Baird, Brewer, and Ridgway. Since the publication 

 of that work a second specimen has come to light ; and a very 

 interesting account of both will be found in Mr. Ridgway's 

 ' Studies of the American Falconidse,' p. 134, from which I 

 extract the following remarks : — " This Buteonine form has 

 no very near relative among the American Falconidse, nor, 

 indeed, among those of the Old World ^ * * -x- General form 

 and size most similar to that of species of Rupornis and As- 

 turina * * "^ * * The general aspect of this peculiar Hawk 

 is that of the smaller short- winged Buteones of tropical 

 America.^' 



Mr. Ridgway describes the type specimen as " everywhere 

 dark greyish brown,'"' and the second example as " above 

 chiefly greyish brown, beneath ochraceous white,'' and adds 

 further particulars in detail respecting both examples, for 

 which I must refer my reader to Mr. Ridgway's own pages ; 

 but I may here transcribe his measurements of these two 

 specimens, the only ones at present known: — ''Wing 10" 10- 

 11*50 inches, tail 6'50-7*30, culmen about "80, tarsus 2*70- 

 2'80, middle toe 1"45-1*60, posterior claw 1, its digit '80." 



Both individuals are believed to have been obtained in 

 California; but many years having elapsed since they were 

 originally procured, though not then recognized as distinct, 



tained by Messrs. Salvin and Godman from Ecuador, and described by 

 the former gentleman under the title of L. occidentalis in the present num- 

 ber of this Journal (posted, p. 496).
