 Antlms acidicaudatus Lesson, Traite d'Orn., 1831, p. 424. 



The one adult male in the collection seems to bo just like speci- 

 mens from Buenos Ayres. ''Iris l)ro\vn.'' 



This well-known species, the Anumhttis aeutieaudatiis of authors, 

 should be called Anvmhiuft fmmimM, as above given, since this name 

 is bv several years the older, as well as of undoubted application. 



SYNALLAXIS SPIXI Sclater. 



Si/naild.ris spi.ri Sclatek, Proc. Zool. Soc. Lond., 1856, p. 98. 



The single example, an adult male, is apparently indistinguishable 

 from the birds of Brazil which represent the typical form of the 

 species. "Iris brown." 



SYNALLAXIS RUFICAPILLA Vieillot. 



Syrinlla.ris rufimpilla Vieillot, Nouv. Diet. d'Hist. Nat., XXXII, 1819, p. .310. 



One specimen, an adult female. " Iris l»rown.''

The single specimen is rather darker, duller, and less rufescent above 

 than one from Brazil, but otherwise does not diti'er. "Iris In-own." 

 There is a good deal of variation in color among e.xamples of this 

 species, but it seems to ])e entirely individual, not geographical.

Fiirncmns rufuff t>'Orbig'SY, Voyage Amer. Merid., Ois., 1835-44, p. 250. 



One specimen; apprecial)lv darker on the l)reast and upper parts 

 than examples from Buenos A3'res; but whether or not this difference 

 is geographical is inconclusively shown by the material at hand. "Iris 

 brown."

A single adult male is in the collection. ''Iris l)rown." 

 The basis of Vieillot's Tif///'t/ rtridix was Azara's Paragua}- bird, 

 the present example coming thus from the type locality. The bird 

 of eastern Brazil, however, is much smaller and slightly paler, ])eing
