NOTES ON THE SPECIES AND SUBSPECIES 
OF PAECILONITTA HKYTON. 
BY OUTRAM BANGS. 
For a long time I have suspected that a much larger form of 
the Bahama duck occupied southern South America, but never 
have had material enough to be certain. Last spring, however,

Museum of Natural History in New York, looking over the 
marvelous series of water birds made by R. H. Beck for the 
Brewster-Sanford Collection, I noticed a fine set of fourteen 
skins of this duck from Argentina. These Dr. Sanford kindly 
allowed me to take home; and, with four from Surinam lent me 
by T. E. Penard, and our own material in the Museum of Com- 
parative Zoology, I was able to bring together a very fair series 
of specimens of the Bahama duck from localities covering in a 
general way its range. 
The Bahama pintail has an extended distribution; it appar-

— Venezuela, Colombia and Ecuador, — but it occurs scattered 
over the remainder of the Continent, and throughout the chain 
of the West Indies to the Bahamas, with one record for Florida. 
In the Antilles it occurs in some islands and not in others,
