452 TINAMID^. 



a specimen from Mr. Underwood procured at Pozo Azul on the 22nd of February, 

 1898. 



T. castaneiceps is scarcely separable from T. ruficeps, but is recognizable from 

 T. rohustus by its darker coloration, and especially by the greater number and closer 

 distribution of the black bars on the upper surface. The head is, moreover, of a 

 deep vinous chestnut colour, while in T. rohustus it is slaty-black and the forehead 

 is grey. The sides of the back of the crown and the sides of the neck are also of a 

 deep sandy-buff colour, with numerous black bars, all of a darker shade than in the 

 last-mentioned species. 



Lieut. Wood states that this bird was heard near the first range of the Cordilleras, on 

 the Rio Truando ^. It had a very loud continued note, not inappropriately compared 

 by the members of the expedition to the whistle of a locomotive engine. 



The eggs of the closely allied species, T. ruficeps, are blue. 



NOTHOCERCUS. 



Nothocercus, Bp. C. R. xlii. p. 957 (1856) ; Salvad. Cat. Birds Brit. Mus. xxvii. p. 509 (1895). 



Nothocercus resembles Tinamus in possessing ten tail-feathers, hidden by the upper 

 tail-coverts, and also in having the hinder aspect of the tarsus rough ; but the scales on 

 the hinder aspect of the tarsus are not prominent on the upper margin, and the toes, 

 especially the middle one, are lengthened {cf. Salvadori, t. c. p. 496). 



Five species are known, four of which are South-American, while one, N. frantzii, 

 is the Central- American representative of the genus.
