498 MR. D. G. ELLIOT ON THE IBIDIN«. [JunC 5, 



Spix (I. c.) from Brazil. A specimen in Messrs. Salvin and God- 

 man's collection, obtained in the vicinity of Bogota, would seem to 

 show that it ranged nearly across the continent. It is a bird of 

 rather dull plumage, having but little of the metallic coloration 

 which renders many of the species of this group so beautiful. I 

 have not been able to learn any thing regarding the economy or 

 habits of the species. 



Sides of head, including the eye and throat, bare of feathers, skin 

 red ; general plumage very dark olive-green, with purple reflections 

 on the neck ; wings dark olive-green, primaries dark rufous brown, 

 secondaries dark purple ; tail dark grass-green, with blue reflections. 

 Total length, without bill, 27 inches; wing 16, tail 11 1, bill along 

 culmen 6^, tarsus 2i.

Mr. Hudson states that this bird appears in May in Buenos Ayres, 

 and is very common on the pampas about latitude 38°. It frequents 

 dry ground, covered with loose grass or low cardoon bushes, and feeds 

 in flocks of from forty to fifty individuals. They swallow the larvae 

 of the large horned beetle, quantities of which insect are often found 

 in their stomachs. About sunset they take wing, uttering loud cries,
