This is a well-marked species of Wren, somewhat resembling Troglodytes hyemalis in general 

 plumage, but easily distiiiguishahle by its larger size and longer tail. It is, in fact, strictly 

 referable to the section allied to Troglodytes dedon^ whilst Troglodytes hyemalis is more nearly 

 allied to Troglodytes europams. 



We owe the discovery of this species, as of many other rare Mexican birds, to the researches 

 of M. Adolphe Boucard. In December, 1857, M. Boucard obtained his first specimens of it 

 at La Parada, a village situated about six leagues fi'om Oaxaca, in the " tierrfp'lria^ of /> 

 Southern Mexico, some 10,000 feet above the sea-level. Other examples were collected, at 

 Cinco Sefiores, in the same district, about three months afterwards. The species, however, is 

 not confined to the western provinces of Southern Mexico, as Prof. Baird records its having 

 been obtained near Orizaba, by Prof. Sumichrast ; and two skms in Mr. Sclater's collection, 

 procured by M. de Oca near Jalapa, and formerly doubtfully referred by him to T. dedon^ appear 

 to be the young of this species. Further south, T. hrunneicolUs extends into Guatemala, examples 

 having been shot by j\Ir. Salvin in the forest-zone of the Volcan de Fuego, at an elevation of 

 about 7,000 feet, in September, 1859. Mr. Salvin also noticed this species on subsequent visits 

 to the Volcano, but generally at a rather higher elevation of about 10,000 feet, where the pine- 

 region commences. It was generally seen in small parties of five or six individuals, among the 

 coarse grass and shrubs, keeping carefully away from view, and uttering a rather clear wren-like 

 call-note. 



Our figure of this Wren is taken from one of the typical specimens in JMr. Sclater's 

 collection, obtained by Boucard at La Parada.
