On the Genus Elaenia. 379 



species, but = E. gaimardi (D'Orb.) and No. 1325 " E. 



albiceps" = E.gigas. Nos. 1336 (oUvacea) and 1337 (rustica) 



belong to one and the same species, viz., E. obscurci (Lafr. 



et D'Orb.).— Cat. Coll. Am. B., pp. 216-218. 

 1865. Geo. 1ST. Lawrence describes E. frantzii and E. 



chiriquensis, the latter being' perhaps the same as E. 



albivertex Pelz. — Ann. Lye, 1ST. H. New York, VIII. , 



pp. 172, 177. 

 1868. A. v. Pelzeln gives us a very good account of the 



Brazilian species of Elaenia, as collected by J. Natterer. 



As new species he describes E. spectabilis (= E.flavogaster 

 spectabilis) , E. cristata, E. albivertex, E. parvirostris, E. 

 elegans (= E. gaimardi) , E. cinerea, E. ruficeps and E. littoralis, 

 the latter not being an Elaenia, but now placed among 

 the Fluvicolinae as Ochthomis littoralis (Pelz.). 



The bird named by him E. modesta Tsch. is not at all that 

 species, but is considered to belong to a new species which 

 will be described in this article. The specimens from Pio 

 Parana, classified by him as E. caniceps, proved to belong 

 to E. c. taczanowskii Beri. 



To A. v. Pelzeln we owe the first knowledge of some of 

 the more difficult species of Elaenia, such as E. spectabilis, 

 E. cristata, E. cdbivertex and E. parvirostris, of which he 

 gave us good descriptions. Nevertheless they were 

 not recognised by some subsequent authors. — Zur Orn.

1870. Descriptions of three apparently new species of Tyrant- 

 birds of the genus Elainea, with remarks on other known 

 species. By P. L. Sclater.— P.Z.S. 1870, pp. 831-835. 



This is another article devoted exclusively to the genus 

 Elaenia. The following species are described as new : E. 

 gigas, E.fallax (redescribed from 1861), E. pudica. Sixteen 

 species are admitted. 



1870. Reinhardt describes E. lundii from Lagoa Santa, 

 which proves to be a young of E. cdbivertex, Pelz., of which 

 Reinhardt had also the adult birds, named by him " E. 

 griseigularis Sel." (cf. Beri, et Hellm., 1905). — Vid.
