come to the great affluent of the Amazons, the river Madeira, where G. pelzelni occurs, 
a species allied to those of Western Mexico. All the members of the genus appear to 
be very rare, G. sallei, the least conspicuously coloured of them, being the commonest 
and having much the widest range.

This beautiful species is one of the rarest of Mexican birds, having a very restricted 
range in the states bordering the Pacific Ocean from Colima to Tehuantepec. The 
first (and for many years the only) known specimen was that in the Brussels Museum, 
named and figured by the late Vicomte Du Bus in his ‘ Esquisses Ornithologiques.’ 
Whether this plate of this unfinished work was ever actually published is a matter of 
doubt; but a copy of it (numbered 34) was accessible to Bonaparte when he drew up 
his description of the bird in the ‘Conspectus Avium’?; and another was furnished to 
Mr. Sclater, and copied in the ‘Proceedings’ of the Zoological Society for 1864 3. 
An imperfect bird in the British Museum Mr. Sclater in 1859* referred to this 
species; but this identification he subsequently * withdrew in favour of Granatellus 
pelzelnt. 
The only specimen we have seen is that obtained by Xantus, which is now in the 
National Museum at Washington. Besides this, Prof. Sumichrast has also met with 
the species on the isthmus of Tehuantepec. 
Of the habits of this bird nothing is recorded; but they probably resemble those of 
G. francesce (next mentioned). 
G. venustus may at once be distinguished from its allies by its conspicuous black 
pectoral crescent, not present in the other species. As regards the recorded colour of 
the iris, statements do not agree—Xantus describing it as white, and Sumichrast as brown. 
The latter colour agrees with that given of its allies G. francesce and G. pelzelni.
