Skins of this Bucco from the State of Panama agree accurately with others from 
Antioquia, as represented on the larger figure of Mr. Sclater’s plate, in being of a 
distinct fulvous tint over the whole of the under surface and the cervical collar, whereas 
in the types of B. radiatus and some other skins of Bogota make the under plumage 
is nearly pure white. The ranges of these two forms cannot be yet traced with 
accuracy. As might be expected the fulvous race is found in Western Ecuador 3, but 
it also occurs on the eastern side of the Andes of that country at Sarayacu, and both 
races occur in collections made by the bird-hunters of Bogota. The latter fact may 
probably be explained by the supposition that the white-breasted form is obtained on 
the eastern side of the cordillera drained by the Rio Meta, while the fulvous form 
comes from the valleys of the Rio Magdalena. The bird-hunters work in both 
directions, and their spoils are mixed in the capital by the merchants who export the 
skins. No Buccois found near Bogota itself. Mr.Sclater duly noted these differences 
in his Monograph ', but was inclined to think the pale colour of the typical birds was 
due to bleaching from damp. We do not agree to this suggestion, but fully believe 
each form has its own exclusive range, and therefore deserving of recognition by name. 
Though noticed by several collectors, Salmon in Antioquia 3, Buckley, Illingworth, 
and Stolzmann+* in Ecuador, we have only the brief note concerning it from the latter 
traveller to the effect that the irides of specimens obtained at Chimbo were ochre of the 
same colour as the abdomen °. 
The evidence of the occurrence of this Bucco in the State of Panama rests on 
specimens sent by Arcé in his later collections made at some place west of the 
Line of Railway. Its name does not appear in the lists prepared by Salvin up to 
1870. M‘Leannan did not meet with it on the Railway itself at the time Lawrence 
was compiling the lists of his collections, but he subsequently sent him a pair, which 
Salvin saw in Lawrence’s possession in 1874.

in his ‘ Monograph of the Bucconide,’ and this number was maintained in his Catalogue
