Show 6 MR. P. L. SCLATER ON THE GENUS SYNALLAXIS. [Jan. 6>, (1858.) P. Z. S. p. 62. In my account of a collection from the Rio Napo two supposed new species of Synallaxis are described as 8. albigularis and S. brunneicauda. The former I now refer to S. albescens. (1858.) P. Z. S. p. 457. I describe S. antisiensis from Ecuador. (1859.) P. Z. S, p. 191. I describe as new S. pudica, S.sticto-thorax, and S.scutata, and give a complete list of the known species and a table of their geographical distribution. (1859.) Pelzeln (Sitz. Ak. Wien, xxxiv. p. 101 et seq.) describes the Synallaxes in the Imperial Cabinet collected by Natterer. S. propinqua, S. alopecias, and S. hyposticta are described as new. (1859.) Cabanis and Heine (Mus. Hem. ii. p. 27> give four species of Synallaxis as represented in Heine's Museum. One, $. ruticilla, is described as new, and Buffon's ' PI. Enl.' 686. fig. 2 is identified, whereby it is shown that Anabates= Synallaxis. (1860.) P. Z. S. p. 66. I describe as new S. erythrops from Ecuador. (1861.) Burmeister, in the second volume of his 'La-Plata Reise,* enumerates the Synallaxes of the Argentine Republic. These he makes eight in number, namely :- Synallaxis humicola (=S. orbignii of m y nomenclature). jiavigularis (=S. sordida). ruficapilla ( = S. frontalis). fuliginiceps ( = Leptasthenura fuliginiceps). phryganophila. cegithaloides (=Leptasthenura cegithaloides). striaticeps. melanops (=Phlceocryptes melanops). (1866.) P. Z. S. p. 183 et seq. Sclater and Salvin record the Synallaxes obtained by Mr. E. Bartlett on the Ucayali. Two are described as new, S. terricolor and S. viilpecula. But, as subsequent investigations show, the former = S. propinqua, and the latter is hardly distinct from S. vulpina. (1867.) The Chilian Synallaxes are enumerated by Sclater in an article on Chilian birds, P. Z. S. p. 324, and those of Whitely's collections in Western Peru, ibid. p. 985. But the species from the last locality named S. orbignii is wrongly determined, and = S. arequipce. (1868.) In their article on Mr. Hudson's Buenos-Ayrean collection (P. Z. S. pp. 140 & 141), Sclater and Salvin include four Synallaxes.-N.B. S. albescens, p. 140, is a lapsus calami for Leptasthenura cegithaloides. See P. Z. S. 1869, p. 632. (1868.) Ann. L. New York, p. 105. Lawrence describes S. rufigenis as new, and includes two other species in his list of Costarican birds. (1868.) P. Z. S. p. 636. Burmeister describes S. sulphurifera, and notes occurrence of S. spixi near Buenos Ayres. (1869.) P. Z. S. p. 417. S. arequipce (previously referred to S orbignyi) is described by Sclater and Salvin. Ibid. p. 636. £. curtata is described and figured by Sclater. |
