4 TTEANNID^. 



considerably below the closed mandible, there is a distinct notch at the end of the 

 tomia. The tarsi are short and stout, covered with distinct scutellae ; the toes short, the 

 outer slightly shorter than the inner. The third and fourth quills are equal and 

 longest— 2nd > 5th, lst=6th. The tail is nearly square at the end, with the exception 

 of the two middle feathers, which are greatly elongated. The web on each side of 

 these feathers is narrow in the middle but widens gradually towards the end, forming 

 an oar-shaped spatule.

The range of this species seems confined to Western Ecuador, Colombia west of the 

 Andes of Bogota, and Central America as far north as Nicaragua. It has also been 

 traced to Guiana i^, but its presence in Bolivia requires confirmation. The allied form 

 G. colonus (of which we believe C. fusdcwpillus to consist, only of darker-headed 

 Individuals) ranges throughout the Valley of the Amazons from the eastern slope of 

 the Andes of Peru, Ecuador, and Colombia to South-eastern Brazil. The two birds 

 may readily be recognized by the presence in C. leuconotus of a light grey dorsal stripe 

 extending from the hind neck to the rump ; in C. colonus the back is wholly black. 



Salmon met with C. leuconotus at Eemedios in the Colombian State of Antioquia ^, 

 but he did not find its nest and made no note on its habits. Most other collectors are 

 also silent on this subject, but Mr. Nutting, who found the species rather common at 

 Los Sabalos on the Kio San Juan del Norte in Nicaragua, says that it builds a nest in a 

 hole in a dry tree after the manner of a Woodpecker — perhaps the abandoned nest- 

 holes of the latter ^^. The note he describes as weak.
