514 BUCCONID^. 



It was first described by Mr. Sclater from a specimen sent from Esmeraldas in 

 Western Ecuador by Eraser i, and, like so many of the birds of that district, was 

 subsequently traced to Panama, where M'Leannan obtained specimens for Lawrence 

 and ourselves * ^. Then Arce found it a little further along the Isthmus, and Salmon 

 at Nichi in the Cauca Valley of Colombia ^. 



None of these collectors have given us any account of the habits of the bird, and on 

 this point we are in ignorance. Of the closely allied B. tectus, Mr. Layard shot several 

 specimens near Para from some low trees in an abandoned clearing. Their stomachs 

 contained fragments of insects. Of. the same bird Natterer says that it lives solitary, 

 perched on high dried trees.

Passing over Wagler's erroneous statement that this species occurs in Mexico ^, we 

 admit this Bucco into the present work on Cassin's record of the capture of a single speci- 

 men on the Truando river by Mr. C. J. Wood, one of the naturalists of Lieut. Michler's 

 Darien Expedition ^. It was only once seen, at the first camp on the Truando after 

 leaving the Atrato. The occurrence of this species at this place is easily explained, 

 seeing that its regular haunts are at no great distance, for it is known to be found near 

 Santa Marta and a short way up the Magdalena Valley at Canuto, where Mr. Wyatt 

 met with it^. He records that the iris is straw-yellow, and that the crops of those he 

 shot were found to be full of beetles. 



Bucco ruficollis is the only species of the genus dealt with here which has the curious 

 cleft tip to the maxilla, referred to in our account of the genus, prominently shown.
