from the Argentine Republic. 137 



26. Bubo virginianus. 



This large bird is not uncommon. I shot two specimens 

 and saw one or two others ; and it was well known. 



27. Otus brachyotus. 



I only got one specimen of the Short-eared Owl, and am 

 not aware of having seen any others ; but I do not fancy that 

 it is rare. 



-f 28. Scops brasilianus. 



I shot one of this species, and saw no others; but it is of 

 course an unlikely bird to be met with, not only from its being 

 an Owl, but from its small size. 



29. Pholeoptynx cunicularia. 



This bird may be seen all over the campo. It seems always 

 to frequent the biscacho holes in the Argentine Republic. 



30. Ardea sibilatrix. 



This species is decidedly scarce. I only had a chance of 

 getting two specimens, male and female, both of which I was 

 fortunate enough to secure. 



+ 31. BlJTORIDES CYANURUS. 



I only procured one or two specimens of this bird, and be- 

 lieve it to be scarce. 



32. Parra jacana. 



I shot this bird on a large swampy laguna some four leagues 

 from where I was living, and it may be common in such places ; 

 but I never met with it on the lagunas near home, which were 

 much smaller. 



-r 33. Erismatura dominica. 



I got one specimen of this bird, and am not aware of having 

 seen any others. The long stiff tail-feathers seemed to me pe- 

 culiar. It is a very expert diver ; and I watched it in a deep 

 part of the river diving and remaining under water a long 

 time on each occasion. 



The above notes only apply to the banks of the Gato, seven 

 or eight leagues from Gualeguaychu ; and such birds as Ardea 

 sibilatrix or Butorides cyanurus raav very likely be commoner
