The type (an adult male) in the Vienna Museum is still the only known 
specimen. A. nattereri is by no means related to A. farinos1, with which 
Dr. Finsch compared it in the original description, but belongs to the group of 
A. aestiva (Linn.) and A. ochrocephala (Gm.), as I have pointed out in Abhandl. 
Bayer, Akad. Wissensch. IT, Kl. xxii. 3. p. 593. It resembles these two species 
in having the edge of the wing and a large wing-speculum bright red, and the 
base of the inner web of the outer rectrices pale red, but differs from A. ochro- 
cephala, with which it agrees in the absence of yellow on the sides of the head, 
by having a broad, bluish frontal band (instead of a narrow, green edge), and by 
the sides of the head, throat, and under parts being decidedly bluish green (not 
pure green or yellowish green). The type measures: wing 122; tail 140; bill 
31 mm. 
I have given (/.c.) an analytical key, which, I hope, will enable ornithologists 
to distinguish A. nattereri from its allies. Although the type is slightly albinistic, 
I think there can be no doubt that it represents a perfectly distinct form. ]

Psittacus festivus Linnaeus, Syst. Nat. x. p. 101 (1758.—* in Indiis,” errore! We fix as type

Nos. 381, 506. ¢ ad., Calama, 12. viii., 2. ix. 1907.—Wing. 210; tail 110, 
108; bill 38 mm, “Iris yellow or red, feet and bill grey.” 
This bird has a rather restricted range in Amazonia, and is not very common 
in collections. Natterer obtained specimens on the upper Rio Branco, in the Rio 
Negro district, and near Borba. It also occurs in Eastern Peru, and possibly 
in Guiana.

Slightly larger than a specimen from Manios, 
Its reported occurrence in Cayenne appears to be open to doubt. 
but not otherwise different.
