46. Orchilus ecaudatus (Lafr. et d'Orb.). 



Todirostrum ecaudatum, Lafr. et d'Orb. Syn. Av. p. 47 ; d'Orb. 

 Voy. Ois. p. 310, t. 33, figs. 1, 2. 



Orchilus ecaudatus, Pelz. Oru. Bras. p. 102. 



A single skin of this scarce species from San Esteban. We 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. We have hitherto 

 called it caniceps, but now find that it is Pelzeln's E. elegans (agree- 

 ing with a Nattererian specimen from Borba), which Pelzeln (J. 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 Swaiuson'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 re- 

 examine his E. itnplacens 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. M\IARCHUS ERYTHROCERCUS, Sp. DOV. 



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.). 



" 3Iyiarchus ferox S " ^- Burm. Syst. Ueb. ii. p. 4/1; Pelzeln, 

 Orn. Bras. p. 116 (partim). 



Myiarchus erythroCercus, Sclater, MS. 



Similis M. cooperi, sed crassitie minore (fere sicut M. ferocis), 

 tarsis brevioribus, et alls magis rotundatis distinguendus. 



Taking Prof. Baird's division of the Myiarchi (Am. B. p. 177), 

 this species, which we introduce under Sclater's MS. name, belongs 

 to the same group as M. crinittcs, 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-
