1868.] ON BIRDS FROM CONCHITAS. H5 



Aramides gigas, Biirm. /. c. p. 504; Schlegel, Mus. d. P.-B. 

 Ralli,]). 14. 



" GaUinetta : eye yellow." This is certainly Vieillot's Rallus 

 ypecaha, founded on Azara s Ypecaha, and appears to be the species 

 indicated by Schlegel as A. g'ujas. We have not yet met with the 

 allied species, which he calls Aramides ypecaha. 



79. Rallus rhytirhynchus, Vieill. ; Scl. et Salv. P. Z, S. 

 18(57, p. 990. 



Aramides rytirhynchus, Burm. I. c. p- 504. 



"Burito: a summer bird; very scarce." — W. H. H. Two skins 

 of this species, which we take to be the liulhis rhytirhynchus of 

 Vieillot, founded upon Azara's "Tpecaha pardo." Upon comparing 

 them with Chilian specimens of Rallus sanguinolentus and the Peru- 

 vian skin of the same species obtained by Whitely (see P. Z. S. 1867, 

 p. 990) it seems necessary to unite them all under the same name. 

 The Chilian bird is certainly larger and has a longer beak ; but 

 Whitely's Peruvian skin is scarcely larger than one of the La Plata 

 birds. 



80. FuLiCA ARMiLLATA, Vieill. ; Burm. I.e. p. 505. 



One immature example, apparently, of this species. " Gallareta : 

 eye hazel ; very common." — W. H. H. 



81. Parra jacana, Linn. ; Burm. /. c. p. 506. 

 Two examples of this wide-ranging species. 



82. Chauna chavaria (Linn.) ; Burm. I. c. p. 506. 

 " Chaja:'—W. H. H. 



83. BuTORiDES CYANURUS (Vieill.). 



Ardeu cyanura, Vieill. N. D. xiv. p. 21, et E. M. p. 1120 (ex 

 Azara). 



B. scapularis, Bp. Consp. ii. p. 128. 



" Summer visitor." Apparently not mentioned by Burmeister. 



84. Ibis falcinellus, Linn. 



T. chalcoptera, Burm. I.e. p. 511. 



" Summer visitor." Cf. Schlegel, Mus. d. P.-B. Ibides, p. 4, et v. 

 Pelz. Novara-Reise, p. 125. 



85. Platalea ajaja (Linn.); Burm. I.e. p. 511.
