Sp. a preecedente fronte fusca distinguenda. After examining a large number of specimens of this form from different localities, I have come to the conclusion to unite them under v. Pelzeln's appropriate name. M y name elegans was first given, founded upon Bogota skins, but changed to elegantior in 1862, on account of there being a Synallaxis elegans of Lesson. In the mean time, however, v. Pelzeln had bestowed the term frontalis upon Bolivian specimens. Amongst the skins from the Jardin des Plantes intrusted to me for examination I find one of D'Orbigny's (Valle Grande, 1834), agreeing sufficiently well with the characters assigned to his S. azarce. These are, however, in my opinion hardly sufficient to warrant specific distinction. 3. SYNALLAXIS MCESTA. Synallaxis mcesta, Sclater, P. Z. S. 1856, p. 26, and 1859, p. 193 - Cat. A. B. p. 152.
