bird of about the Grackle’s size but adds “‘there is no certainty about it 
whatever” and so wisely refrains from naming it.— W. S. 
Richmond’s Third Supplement to Waterhouse’s “‘ Index Genera 
Avium.” !— This welcome publication follows the plan of its predecessors 
except that the types of the genera have been determined according to the 
rules of the International Code of Nomenclature and derivations of names 
have been omitted except when furnished by the original authors. Some 
600 names are listed of which more than half have been published since 
1905 and of these about 175 are credited to Mr. Gregory M. Mathews. 
Perhaps the most important feature of this supplement is the list of errors 
in Waterhouse’s ‘Index.’ This consists of vernacular and other names 
which have no generic status at the citations given, errors in spelling and 
in statement, all of which are corrected by Dr. Richmond, and nomina 
nuda, for which the proper citations are given. Lists of Linnzean genera 
which are citable at earlier date than those given by Waterhouse (mainly 
due to his adoption of the 12th in place of the 10th edition of the Systema) 
are given, as well as original references to Bonaparte’s genera which ap- 
peared originally in the ‘Ateneo Italiano’ and corrections to the two 
previous “‘Supplements.”’ 
With this pamphlet before them systematic ornithologists are for the first 
time in possession of accurate references to all the genera of birds so far as 
known. That afew still remain to be unearthed from obscure publications 
goes without saying, but they will not begin to approach the number in- 
cluded in the present list which latter represents the results of the pains- 
taking researches of both Dr. Richmond and Mr. G. M. Mathews during 
the past ten years. 
When one considers that much of Dr. Richmond’s time has necessarily 
been taken up in searching out the true date of issue of many wrongly 
dated publications it seems like the ironry of fate that his own paper should 
be antedated. It seems high time that someone in charge of the scienti- 
fic publications at Washington takes steps to check this unfortunate 
practice.— W. S. 
Aves in the Zoological Record for 1915.2— Mr. W. L. Sclater is again 
the author of that section of the Zoological Record devoted to birds, and 
has compiled a list of 934 titles for the year 1915, with the usual rearrange- 
ment of references under various subjects — geographic, economic, plumage,
