Orchilus ecaudatus, Pelz. Orn. Bras. p. 102. A single skin of this scarce species from San Esteban. W e had not previously met with it. 51. ELAINEA ELEGANS, Pelz. Orn. Bras. p. 179. In Sclater's collection there are skins of this species from Bogota, Cayenne, Pebas in Eastern Peru, and Panama. W e have hitherto called it caniceps, but now find that it is Pelzeln's E. elegans (agreeing with a Nattererian specimen from Borba), which Pelzeln (I. c.) considers distinct from E. caniceps of Swainson, also collected by Natterer. It is quite certain, moreover, that the present bird does not agree satisfactorily with Swainson's figure (Orn. Dr. t. 49). 52. ELAINEA PLACENS, Sclater. The occurrence of this species as far south as Panama has been already recorded (P. Z. S. 1864, p. 359). Sclater has also recently received Bogota skins of the same bird. This has led him to reexamine his E. implacens from Ecuador (P. Z. S. 1861, p. 408), which he is now convinced is not specifically separable. Pelzeln's E. implacens, Orn. Bras. p. 108, is probably the same species. 56. MYIARCHUS ERYTHROCERCUS, sp. nov. Suiriri pardo y roxo, Azara, Apunt. ii. p. 143. no. 195. Tyrannus crinitus, Hartl. Ind. Az. p. 13; d'Orb. Voy. Ois. p. 306. Tyrannus irritabilis, Bp. Consp. i. p. 189 (nee Vieill.). "Myiarchus ferox cf " I Burm. Syst. Ueb. ii. p. 471; Pelzeln, Orn. Bras. p. 116 (partim). Myiarchus erythrocercus, Sclater, M S . Similis M. cooperi, sed crassitie minore (fere sicut M. ferocis), tarsis brevioribus, et alis magis rotundatis distinguendus. Taking Prof. Baird's division of the Myiarchi (Am. B. p. 177), this species, which we introduce under Sclater's M S . name, belongs to the same group as M. crinitus, M. cooperi, and M. cinerascens, in which the broad rufous edgings of the inner webs of the tail-feathers are continued nearly or quite to their termination. It is the only species with these broad rufous edgings yet recognized in South America, where it appears to be extensively diffused. Sclater's collection contains examples from Bahia and Tobago; and in the Museum of Copenhagen is one from Venezuela, which has been compared by Prof. Reinhardt with Sclater's skins, and found to be identical. If we are not mistaken in our synonymy, it is also found in Paraguay and Bolivia. Bonaparte appears to have recognized this bird as T. irritabilis; but that name of Vieillot is a mere synonym of T. crinitus. Bur- |
