PREFACE. 
through the press, the Editor found that many names of old standing were not 
included in it nor in Scudder’s work. As these two lists form the only satisfactory 
channel for bringing to the notice of the public names that have been proposed 
for use, it appeared to be highly desirable that the Index should include all 
names that could be obtained by such an amount of work as was consistent with 
the means at the disposal of the Compiler and Editor, and with the fact that an 
early issue of the volume had been promised. In order to complete the Index a 
system of collation with the Indexes of important zoological catalogues, etc., has 
been carried on while the work has been passing through the press. A great 
many omitted names have thus been discovered.* These have been added to 
the manuscript and proof so far as was possible ; and in cases where the sheets 
had already been printed off have been consigned to a supplement. Both 
Editor and Compiler greatly regret the division thus entailed, but it is clearly 
desirable to have this supplementary list issued in company with the main Index. 
It will at any rate ensure that the names shall find their proper places in the 
next complete list that may be issued. 
The number of names contained in Scudder’s list is about 80,000, and the 
additional number in this Index is about 40,000. The numbers of new generic 
names in the Indexes of the “ Zoological Record ” for the twenty-one years hero 
collected are as follows : —

* It is a curious fact that the omissions are proportionately greater in the Ver- 
tebrate than they are in the Invertebrate division of the Animal Kingdom. 
t In this year, 1888, there was included a great many names belonging to the year 
1869, reducing the number of the year’s names to some 1200 or 1300.
