ORNITHOLOGICAL OBSERVATIONS. 
this bird, and it is certainly a very close ally of the C. sttticolor, 
of which a figure is given in Gray's Genera, pl. 34, but still I 
think distinct from that species, and will therefore stand next to it 
as Conirostrum rufum, De Lafr., making a seventh of the genus, of 
which the other six species are correctly enumerated in the Prince 
of Canino’s Conspectus, page 401. 
Latham, Gen. Syn. Supp., p. 108, describes a bird afterwards 
named by him, Ind. Orn., p. 558, Sylvia plumbea, as follows :— 
Size small; length 33; bill short, dusky brown ; plumage above | 
deep lead colour, nearly black, beneath pale ash colour; quills and 
tail dusky; legs deep brown; native place uncertain. 
This has been identified by M. Cabanis with a bird found by 
M. Tschudi on the coast and wood-region of Peru, and formed into 
a * Dacnis plumbea,” Faun, Per. pp. 37, 236. He gives the follow- 
ing description of it:—Head bluish-gray; back and upper wing- 
coverts bright gray-blue; remiges black-brown, on the outer barb, 
with an olive-green on the base of the inner barb with a broad | 
white border ; rectrices the same, without the white border on the 
inner barb; chin and breast bright whitish-gray ; the under parts ° 
greenish-gray ; middle of belly and crissum yellowish-white. 
This bird I have never seen.
