LIST OF DIURNAL BIRDS OF PREY. 



* I may add to my remarks on this scarce sjiecies that the collection of Messrs. 

 Salvin and Godman now contains four examples, all from the Argentine Republic, and 

 all marked as females by the collectors. I have had the opportunity of measuring 

 these specimens, with the following results : — 



Wing 6-50to7 



Tarsus 1 70 to 180 



Middle toe, s. M MO to 1-25 



* The several species forming the genus Dissodectes are included by Mr. Sharpe in 

 the group to which he applies the generic name of " Cerchneis," and in this he is 

 followed by Signor Barboza du Bocage ; most other authors have placed them in the 

 genus " Falco."
