Show 1871.] CERTAIN SPECIES O F TYRANNIDAE. 755 Myiozetetes luteiventris, Sclater, Cat. A. B. p. 219; Pelz. Orn. Bras. p. 109. This species I founded, in 1858, upon a skin, in not verv good plumage, obtained, through the Maison Verreaux, from the Rio Napo. I have been recently fortunate enough to find a second example in a collection of birds from Oyapok, in Cayenne, transmitted to me for examination by Madame Verdey of Paris. This second skin is also not quite adult, but shows a small concealed crest, proving that, as H. v. Pelzeln has already pointed out in his remarks (Orn. Bras. p. 109), this species is not different in this respect from other members of this group. I use this specimen to amend the specific characters formerly given, as follows:- MYIOZETETES LUTEIVENTRIS. Obscure olivaceus, alis caudaque fusco-nigris, rufescente marginatis: crista pilei celata igneo-rubra flavo mixta : gutture albo abdomine et subalaribus fiavis : remigum marginibus interioribus pallide rufescentibus : long, tota 5*3, alee 2*75, caudce 2*3. Hab. Eastern Ecuador; Rio Negro and Rio Maderira (Natt.) ; Cayenne. This species forms a very distinct third member of the second section of Myiozetetes, without the white superciliaries. It is not unlike M. granadensis, but smaller in size and much darker above. So much for the species of Myiozetetes. Of the nearly allied genus Conopias, Cab. & Hein.*, I have only recognized one species in m y American Catalogue, namely Conopias superciliosa = Tyrannula superciliosa, Sw. (1841). I now find that Swainson's name must give place to trivirgata oi P. Max. (1831), this bird being clearly the Muscicapa trivirgata of Max. Beitr. iii. p. 871. This synonym was wrongly referred in m y American Catalogue to Myiozetetes similis. Closely allied to C. trivirgata, but distinguishable by its larger size, white throat, and brown back, is Myiozetetes inornatus oi Mr. Lawrence. Tschudi's Tyrannus cinchoneti (of which I have lately obtained a Bogota skin) seems to be a third allied species. All these three Tyrants have broad and distinct superciliary markings prolonged to the nape, and a dark pileus without any coronal patch. Their synonymy will stand as follows:- 1. CONOPIAS TRIVIRGATA. Muscicapa trivirgata, Max. Beitr. iii. p. 871 (1831). Tyrannula superciliosa, Sw. Orn. Dr. pl. 46 ; Burm. Syst. Ueb. ii. p. 475. Muscicapa pitangula, Licht. in Mus. Berol. * Mus. Hein. ii. p. 62 (1859). Mr. G. E. Gray (Hand-list, i. p. 354) seems to give Myiacleptes of Eeichenbach (1850) priority. But I cannot admit that a mere cut of the head and wing (such as that in Eeichenbach's Systema, pl. Ix.), without even a type species named, is sufficient to establish a priority. |
