1883.] BIRDS OF THE APnENTINE REPUBLIC. 39 



Not uncommon on the highlands covered with thorny brushwood, 

 where I obtained my specimens. 



[Mr. White's specimens are decidedly of this species, of which I 

 have examples from the Rio Negro {Hudson, P. Z. S. 1872, p. 460) 

 and the Sierra de Cordoba {Ddririff, P. Z. S. 1879, p. 460).] 



9. Cnipolegus hodsoni (Scl.). 



c?. Cosquin, Cordova, Arg. Rep., June 19, 1882. 



Iris dark brown. 



This bird was shot amongst the tolerably thick-wooded and lofty 

 mountain- slopes, where I found it frequenting the topmost tree-twigs 

 and darting thence at passing insects. 



[Not examined by P. L. S.] 



10. An^retes parulus (Kittl.). 



cJ . Cosquin, Cordova, Arg. Rep., June 26, 1882. 



?. „ „ „ June 23, 1882. 



Iris dark. 



In the thick brushwood near the river I found this little bird not 

 uncommon. 



11. Cyanotis AZAR.E (Naum.). 



c? . Cosquin, Cordova, Arg. Rep., Sept. 22, 1882. 



2 . La Plata, Buenos Aires, Arg. Eep., Nov. 10, 1882. 



Iris sky-blue. 



These pretty httle birds frequent in considerable numbers the 

 rushes on some lagoons near La Plata. They skip from reed to reed 

 about a foot above the surface of the water, all the while uttering a 

 peculiar creaking little note, much resembling that of the cricket. 

 At Cosquin, however, I obtained only one specimen ; and that was on 

 the river. 



12. Synallaxis striaticeps (Lafr. et D'Orb.). 



S . Cosquin, Cordova, Arg. Rep., June 19, 1882. 

 2. „ „ » July 25, 1882. 



Iris brown. 



This species is common amongst the woods on the mountain- 

 side. 



[Not examined by P. L. S.] 



13. Synallaxis sordida (Kittl.). 



S . Cosquin, Cordova, Arg. Rep., Aug. 9, 1882. 



$. „ „ „ June 15, 1882. 



The abode of this bird seems to be the highlands, where it loves to 

 frequent small shrubs and brushwood, into the deepest shade of which 

 it penetrates. When startled, its flight is quick and dipping from one 

 bush to another, uttering meanwhile a pretty trilling cry. 



[Mr. White's specimens belong to this species, and not to S. 

 humicola as he had supposed. — P. L. S.]
