Mr. Fraser obtained four skins of this fine Ortalida at Babahoyo 
in 1859; but Sclater incorrectly referred it to O. ruficeps of Wagler, 
with which he was not then acquainted. 
We were preparing to give it a new name, when Sclater found a 
specimen of the same bird in the Berlin Museum with a MS. name 
of Natterer’s attached to it. Lichtenstein has given ‘‘ Cumana”’ as 
the locality of this example; but Sclater ascertained on inquiry that 
the specimen in question had been received alive in one of the Royal 
Gardens, and had died in captivity, so that the locality assigned to it 
is not reliable. 
In the Paris Museum there are two skins of this Guan obtained 
at Guyaquil by the expedition of the ‘ Danaide’ in 1843.
