Birds of Paraguay. 
90. Synallaxis spixi. 
Synallaxis spixi Sclater, P. Z. S. 1856, p. 98 (Brazil) ; 
Berlepsch, J. f. 0. ]887, p. 132 (Minas and S. Brazil to 
Buenos Ayres) ; Oberholser, Proc. U.S. Nat. Mus. xxv. 
p. 134 (1902: Sapucay) ; Sclater, Cat. B. Brit. Mus. xv. 
p. 42; Ihering, Bevista Mus. Paulista, vi. p. 328 (Paraguay); 
Hellmayr, Abhandl. Akad. Wiss. Miinchen, xxii. p. 631. 
Synallaxis furvicaudatus Bertoni, Aves Nuev. Paraguay, 
p. 76. 
a. S' ad. Sapucay, June 29, 1904. 
Bill black above, greyish below; tarsi and feet bronze- 
green ; iris light brown. 
b. S ad. Sapucay, August 29, 1904. 
I have followed Dr. Ihering in placing S. furvicaudatus 
of Bertoni as a synonym of the present species, as the 
specimens from Paraguay are identical with others from 
Brazil. 
91. Synallaxis albescens. 
Synallaxis albescens Temm. PI. Col. iii. pi. 227. fig. 2 
(1823: Brazil) ; Berlepsch, J. f. O. 1887, p. 132 (Mendoza 
and Buenos Ayres to Central Brazil); Sclater, Cat. B. Brit. 
Mus. xv. p. 43. 
a. S ad. Sapucay, June 19, 1904. 
Bill dark horn-coloured above, pinky-grey below; tarsi 
and feet dry pea-green; iris light brown. 
This species appears to be new to the avifauna of Paraguay, 
although it has been recorded from the Argentine. 
92. Synallaxis cinerascens. 
Synallaxis cinerascens Temm. PI. Col. iii. pi. 227. fig. 3 
(1823 : Brazil); Sclater, Cat. B. Brit. Mus. xv. p. 48. 
a. S ad. Sapucay, July 20, 1904. 
Bill black; tarsi and feet light horn-coloured with a 
greenish tinge; iris reddish brown. 
This example is identical with others from Ypanema and 
Bio Grande do Sul. The species has not been previously 
recorded from Paraguay.
