592 MR. E. W. WHITE ON BIRDS [June 20, 
rely upon his own resources in a way that renders collecting very 
arduous, besides being at times an object of suspicion. Owing to 
my bad state of health, I did not commence operations upon the 
avifauna of this part of the Neotropical region until the year 1880 ; 
and then my trips to Oran, Misiones, and other promising districts 
were, from one cause and another, generally so hurried, that, as I was 
unable to remain in desirable spots even for a few days, much less 
through the season (a step so essential to the observation of the 
habits of birds), not only will my notes be characterized by some- 
what of baldness, but certain families, such as the Alcedinidee, will 
be found entirely, and others, such as the Strigide, but poorly 
represented, which undesirable result has been further contributed 
to by the loss of some of my manuscripts. 
It is not to be inferred from this, however, that many species of 
these families have not come under my observation, but simply that 
as yet they form no part of my private collection. However, to the 
remarks and data herewith furnished I have paid much attention 
to secure accuracy, and I indulge in the hope that they will be con- 
sidered of some value. With regard to the nomenclature, in which 
I have followed the ‘ Nomenclator Avium Neotropicalium’ of Messrs. 
Sclater and Salvin, I anticipate there will be found few inaccuracies 
of any import, although Buenos Aires does not possess the facilities 
which London enjoys for the accurate determination of species. 
My earnest desire is to be able before long to supplement the 
present with additional notes, until this country shall be pretty well 
exhausted of its feathery inhabitants. 
Buenos Aires, May 5, 1882. 
[I have examined several series of Mr. White’s birds, and have 
great pleasure in testifying to the general accuracy of his determi- 
nations. But, as he has given me full authority over his MS., I have 
thought it right to add a few remarks in certain cases when I have 
not seen specimens and there is some cause to doubt. These 
remarks are indicated by my initials—P. L. 8S.

Iris dark brown. 
Shot in the woods around the old Jesuit ruins. These birds are 
plentiful all over Misiones, and are often kept as cage-birds, as they 
have a pleasant whistle.

Iris sepia. 
During my sojourn in Oran I did not meet with many of this 
species ; but in the dense woods of Misiones they are abundant ; and
