his name has been translated or changed from its original form. 
Dr. Gundlach, whose name is so intimately associated with the zool- 
ogy of Cuba, is usually known as John Gundlach or Juan Gundlach, 
but he was born in Germany and his original name was Johann 
Christoph Gundlach. Dr. Gustav [Ferdinand Rudolph] Radde 
was born in Germany but spent most of his life in Russia and his 
name may be found in Russian biographies in the form Gustav 
Ivanovich Radde. Similarly Dr. Ladislas Taczanowski’s name is 
sometimes given as Ladislas Casimirovich Taczanowski, in con- 
formity with Russian custom. 
In all these cases the name is given in full and any part which 
may have been dropped is enclosed in brackets. 
BIOGRAPHICAL INDEX 
No attempt was made in the former Index or in the body of this 
index to bring together references to the widely scattered biographical 
notes and obituaries of ornithologists and members of the Union. 
To supply what seemed to be an important omission a list of these 
notes was arranged in alphabetical order. The obituaries vary from 
simple announcements of death to elaborate memorial addresses, 
some of which are accompanied by portraits or occasionally by a 
bibliography. When it was decided to bring the list down to date 
and include all deceased members of the Union, it was found that 
about sixty names were accompanied merely by the date of death, 
and of the 200 or more obituary notices fully half lacked some im- 
portant item of time or place of birth or death. In supplying these 
data recourse has been had to every available source of information 
and much assistance has been rendered the committee by corre- 
spondents in all parts of the country and abroad. Discrepancies in 
statements of age and in dates are frequent, and are evidently due to 
imperfect information or lack of opportunity to check up the data 
at the time the original notices were prepared. When important 
discrepancies have come to light special efforts have been made to 
ascertain the correct data and attention is called to an apparently 
erroneous date by enclosing it in parentheses with the word “ not.” 
Dates of birth are sometimes uncertain and cannot be given nearer 
than the year. In the very exceptional case of Audubon the dates: 
are variously assigned from 1772 to 1783, although 1780 is the year 
usually accepted; the day is sometimes given as May 4 and some- 
times as May 5. The latter seems to be based on the best authority
