204 VIREONIDZ. 
highlands of Costa Rica in 1864 formed the basis of Prof. Baird’s description!; and 
these same specimens seemed to have been again referred to in Mr. Lawrence’s? and 
Dr. von Frantzius’s lists*. They also furnished the characters in the table given of the 
members of the genus by Messrs. Baird, Brewer, and Ridgway 4, where the position of 
the species in the genus is carefully defined. Up to the time of publishing our second 
list of Veraguan birds* no specimen of Vireo carmioli had reached us; but we have 
since received an example, which is now figured, from the slopes of the Volcano of 
Chiriqui. We have also two specimens obtained by Rogers on the Volcan de Irazu, 
in Costa Rica, 
b. Ale rotundate, haud fasciate ; cauda elongata; rostrum valde robustum, 
culmine alto.

Hab. Mextco!, Tres Marias Islands (Grayson?*4, Forrer), Quiotepec in Oaxaca 
(Sumichrast *). 
A peculiar species, both as to its coloration, its strong bill with sharp culmen, its 
short wings, and long tail. It was first described and figured by Mr. Sclater from a 
specimen supplied to him by M. Parzudaki of Paris from some part of Mexico, the 
precise locality not being recorded}. The late Col. A. J. Grayson ¢ afterwards discovered 
it in the Tres Marias Islands, where he says it is quite common, frequenting all parts 
of the woods, uttering from time to time a cheerful little song. Mr. Forrer also 
found it during a recent visit to these islands, and sent us a specimen. This Vireo, 
however, is not confined in its range to these remote islands, but also occurs on the 
mainland, as Prof. Sumichrast met with it in the State of Oaxaca 5, and sent a specimen 
to the Smithsonian Institution, which, through the kindness of the authorities, we have 
had an opportunity of examining. This was shot on August 8th, 1868, and Mr. Forrer’s 
on April 18th, 1881. 
Nore.—TIwo other species of Vireo probably occur in the unexplored parts of North- 
western Mexico, but, as yet, are only known from Arizona, on the other side of 
our frontier. These are V. vicinior and V. pusillus, species both discovered by the 
energetic ornithologist Dr. Elliott Coues, and both fully described in his work on the 
Birds of the Colorado Valley.
