The Register of the Zoological iVnzeiger here- 

 with presented for volumes XXI - XXV (No. 549 - 

 684) iike the Register for Voltimes I - X, XI - XV 

 and XVI - :Œ (1889, 1893 and 1899) corresponds to 

 the Bihliographioa Zoologica, Volumes III - VII 

 and like those that have already appeared, this 

 one contains (the following) ;- 



1. All the authors together v/ith the 

 principal words of the titles of the articles 

 written by then, 



2. All the systematic names that occur in so

 (n.g.) so that these four Registers taken together 

 contain all the new genus names published from 

 1878 - 1902. 



3. All the Society (Oesellschaftes) articles 

 and periodicals arranged according to the leading 

 words of the title.

 publishing a special habitat and specimen index to 

 avoid increasing the size of the Register to so 

 great an extent.

 one fifth the space of time, it is nevertheless 

 larger than the first Register which covers twice 

 the period of time and this though it has the same 

 "get up". Yet both these (sections) are here 

 replaced in so far that the specimen as well as 

 the habitat are indicated as accurately as possible 

 with their respective genus and specie names; by 

 looking through the entire Register, the statements 

 relative to any subject will be found in as com- 

 plete a form as possible, 



3o the object in viev; will be recognized, 

 which (object) consists principally in the fact
