Darwin's Tinamou was not obtained by the naturalists of the Princeton 

 Expeditions. The description given is based on material in the British 

 Museum of Natural History. 



Mr. Hudson's remarks on this bird and its habits have appeared under 

 the last species, N. maculosa, as they seemed more pertinent in that con- 

 nection. 



Of Nothura minor {= Nothura darwini) Darwin writes: 



"I procured a specimen of this bird at Bahia Blanca, in northern Pata- 

 gonia, where it frequented the sand-dunes and the surrounding sterile 

 plains. Its habits appear similar to the N. major, but it lies closer and 

 does not so readily take to the wing. It is the smallest of the species 

 mentioned in this work, and its plumage is less distinctly spotted. The 

 tgg of this bird is described below. Spix's specimens were obtained at 

 Tijucco in Brazil. The figure in his work on the Birds of Brazil, differs 

 slightly from mine, in being less marked on the breast." (Darwin, 

 " Voy. H. M. S. Beagle," Zool. Bds., 1841, p. 119.)
