6 MR. P. L. SCLATER ON THE GENUS SYNALLAXIS. [Jan. b, 



(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 

 S. 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. pudiea, 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 SynaUaxes in the Imperial Cabinet collected by Natterer. S. 

 propinqua, S. alopecias, and S. hyposticta are described as new. 



(1859.) Cabanis and Heine (Mus. Hein. ii. p. 27) give four 

 species of Synallaxis as represented in Heine's Museum. One, S. 

 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 SynaUaxes of the Argentine Republic. These he 

 makes eight in number, namely : — 



Synallaxis humicola (=-S. orbignii of my nomenclature). 



flaviguluris ( = S. sordida). 



rvjicapilla ( = 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 

 SynaUaxes obtained by Mr. E. Bartlett on the Ucayali. Two are 

 described as new, <S. terricolor and S. vulpecula. But, as subsequent 

 investigations show, the former = S. propinqua, and the latter is 

 hardly distinct from S. vulpina. 



(1867.) The Chilian SynaUaxes are enumerated by Sclater in an 

 article on Chilian birds, P. Z. S. p. 324, and those of Whitely's col- 

 lections 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 col- 

 lection (P. Z. S. pp. 140 & 141), Sclater and Salvin include four 

 SynaUaxes. — N.B. S. albescens, p. 140, is a lapsus calami for Lepta- 

 sthenura 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 t 

 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. S.curtala 

 is described and figured by Sclater.
