Aulacorhamphus wagleri, Gould^ Mon. Rliamph. ed. 2, 

 pi. 48; Sclater, P. Z. S. 1859, p. 384. 



Of this rare species the type-specimen in the Munich 

 Museum for many years was the only one known; but in 1858, 

 M. Boucard obtained an example at Sacatepcc in the Mexican 

 State of Oaxaca; and we now find another in Mrs. Smithes 

 collection which was shot at Amula, a village in the State of 

 Guerrero, at an elevation of about 6000 feet above the sea, 

 in the Sierra Madre del Sur. The species is very closely 

 allied to A. prasinus, but may at once be distinguished by 

 having the base of the maxilla black, with the exception of 

 the yellow line which separates it from the naked orbit. We 

 also notice that the frontal feathers in A. pavoninus are 

 yellowish at the base, a feature not seen in the allied species. 



There can be no doubt that A. pavoninus is the right name 

 to use for this bird, notwithstanding Sturm's statement as to 

 its application by Wagler in the Munich Museum. 



Chrysotis viridigenalis. 



Chrysotis viridigenalis, Cassin, Proc. Ac. Sc. Phil. 1853, 

 p. 371; Jouru. Ac. Phil. iii. p. 153, pi. 13; Souance, Icon. 

 Perr. pi. 31 (lower figure). 



Chrysotis coccineifrons, Finsch, Papag. ii. p. 540 (partim). 



The origin of C. viridigenalis of Cassin has always been a 

 matter of doubt, and till recently a menagerie specimen in 

 the possession of Mr. Sclater, said to have come from 

 Colombia, was the only one we had seen answering to the 

 figure. It now turns out that the bird is not at all un- 

 common in eastern Mexico from Misantla northward to the 

 limit of the forest districts. Godman obtained several speci- 

 mens at Misantla during his recent expedition, and botli 

 Richardson and Armstrong procured numerous examples, 

 the most northern point recorded being Montemorelos, in 

 lat. 25° 15' N., on the Eastern Sierra Madre. 



Besides C viridigenalis, the following Parrots are found in 

 this region, namely, C. autumnalis, C. levaillanti, ' Ara mili- 

 tarist Conurus holochlorus and C. aztec. None of these reach 

 the banks of the Rio Grande, and the limits of their
