of the species of Flamingo. 441 



greater length obliquely straight, and then suddenly curved to 

 the lower surface. The bill is largely covered by a membrane 

 round the base, which extends narrowly round the eyes. 



This species may constitute a distinct subgenus under the 

 appellation of Phoenicurodias. 



Figures 9 and 10 represent the curiously formed bill of the Fla- 

 mingo of the Peruvian Andes. It is comparatively short and ele- 

 vated, WHth the culmen and lateral margin greatly arched from the 

 base to the tip ; the posterior margin of the lower mandible is 

 curved to the under surface without any sign of an angulation ; 

 the lateral surface that runs parallel to the lateral margin of the 

 lower mandible is very much swollen on the sides, so as to give a 

 rather wide and flattened surface when viewed in front. The 

 upper mandible is remarkably narrow throughout its length, and 

 rests, when closed, between the swollen sides of the lateral mar- 

 gins ; the base of the bill is furnished with a narrow membrane, 

 which widens and expands to the eyes in a somewhat trian- 

 gular form. 



Prof. Philippics figure of the bill is rather different from the 

 one here represented, as the culmen and lateral margins are 

 comparatively straight, which give rise to a doubt, at first sight, 

 whether it could ever have been meant for the same species. 



This remarkable bird is also noticeable for not possessing a 

 hind toe, which is found in all the other species : it was therefore 

 formed by the late Prince C. L. Bonaparte into a separate sub- 

 genus under the name of Phoenicoparrus.
