514 BUCCONID. 
It was first described by Mr. Sclater from a specimen sent from Esmeraldas in 
Western Ecuador by Fraser}, and, like so many of the birds of that district, was 
subsequently traced to Panama, where M‘Leannan obtained specimens for Lawrence 
and ourselves4#®, Then Arcé 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.
