highlands of Costa Eica 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 Eidgway ^, 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 Eogers on the Volcan de Irazu, 

 in Costa Eica,

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 ^, 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. 



Note. — Two 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- mcinior 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.
