latter I often met with in tlie province of Cordova, but am 

 not aware of having seen it in Entre Rios. 



Hi. ROSTRAMUS S0C1 LBILIS. 



So far as I know, I only procured one specimen of this 

 species. It flew overhead by itself as we were Lying on the 

 grass. The species appeared to he unknown toevery one who 

 saw it ; but this evidence is not worth much, as hardly any 

 one in the country took any interest in natural history. I 

 believe, however, from my own observation, that this and 

 Geranospiza ccerulescens arc very rare. 



The Geranospiza is such a remarkable-looking bird that 

 even a native would have noticed il. 



17. A.CCIPITER ERYTHROCNEMIS. 



One specimen of this bird was shot by my companion. I 

 am not, aware of having seen any others, hut think it would 

 be a very likely bird to escape observation. 



H-18. Geranospiza affiRULESCENS. 



Of this bird I never saw but one specimen, which I shot; 

 and on showing it to one or two natives, they said they had 

 never seen one like it; nor had my friend, who had been in 

 the habit of shooting for several years in the country. The 

 crop was full of bits of the unfledged young of some bird ; and 

 as there were nests of Parrots and Caranchos near, I have no 

 doubt they supplied the victims. The slate-coloured plumage, 

 orange-red legs, bright yellow eyes, and long brightly coloured 

 tail make this a very handsome bird. 



11). TlNNUNCULUS SPARV10R1US. 



This is another most beautiful little Falcon, and one of the 

 commonest birds in the country. 



■f- 20. Hypoteiorchis femoralis. 



A beautiful and most graceful Falcon, reminding one 

 strongly both of the Peregrine and the Hobby, especially the 

 latter, though its wings are not quite so long as those of the 

 Uobby. This bird is not uncommon, and is oftenor seen at 

 sonic distance from the woods than any other Hawk 1 have 

 mentioned.
