Show 834 MR. P. L. SCLATER ON N E W TYRANNIDAE. [Dec. 6, by Mr. Lawrence. Failing to do this I have resolved to describe as new. Fig. 3. Elainea pudica. This Elainea belongs to the third section of the genus as arranged in m y " Index generis Elainese" *, having no vertical spot whatever. It is remarkable for its short and compressed bill. I add a list of, with a few remarks on, the species of this very puzzling genus of Tyrannidse represented in m y collection. Sect. A. Species capitis subcristati plumis intus albis. 1. E. pagana (Licht.); Scl. Cat. A. B. p. 216. Under this name I now believe we shall have to reunite the species separated by me as E. subpagana and E. semipagana, and thus recognize one rather variable species extending from Southern Mexico to the wood-region of S.E. Brazil. I have now fifteen skins of this bird from various localities, and so have a better opportunity of judging of them than formerly. It should be mentioned, however, that there is much more white in the crests of northern specimens than in those from S.E. Brazil. 2. E. riisii, Scl.; Cat. A. B. p. 217, ex ins. S. Thomas. I am now a little doubtful about the validity of this species also. It may turn out to be only the same as the former; but more specimens are required, especially from the intervening islands between S. Thomas and Tobago. 3. E. albiceps (Lafr. et D'Orb.). I am now disposed to unite under this name the specimens from E. Peru, Chili, and Buenos Ayres usually called E. modesta (Tsch.), and birds from Western Peru called E. albiceps by Mr. Salvin and myself (P. Z. S. 1868, pp. 174 et 568), although the latter are unusually large in size, and of a rather purer white on the throat. If this view be correct, the range of this species will be a wide one, from * P. Z. S. 1801, p. 406. |
