Char. — Crown largely or wholly sooty black; no occipital crest.

In default of specimens of rohustus I am unable to determine whether 

 ftiscipennis is separable from that form. The close relation between 

 fuscipennis and castaneiceps is shown by the occurrence of a virtually 

 typical specimen of the former in the Canal Zone and by Salvadori's refer- 

 ence of a specimen from Veragua, the type region of castaneiceps, to fusci- 

 pennis! 



Of ' Tinamus serratus' (Spix) I have seen no specimen. 



' Tinamus solitarius' (Vieill.) is obviously only a large race of T. major. 

 I have, however, but one specimen.

Inhabits the Tropical Zone of the Pacific Coast, evidently intergrading 

 at the south with T. m. latifrons and at the north with T. m. fuscipennis. 

 Colombian specimens have the feathers of the occiput decidedly longer than 

 those from the Panama Canal Zone and thus approach latifrons in this 

 respect. This character first appears in specimens from Tacarcuna in 

 eastern Panama, but is more pronounced in those from the Atrato. 



A specimen collected by the Shiras Expedition, near Gatun, in the Canal 

 Zone, has the crown sooty black with only a trace of ochraceous. It can 

 be exactly matched by specimens of T. m. fuscipennis from Nicaragua (if 

 that race be valid), which has the crown apparently always sooty, with 

 sometimes traces of ochraceous.
