94 THE ZOOLOGIST. 



the Moths of India were in the present position of the Moths of 

 Africa, the game of happy hunting grounds for specialists, but a 

 hopeless study for the average lepidopterist. The material was 

 comparatively scanty, with a systematic literature obscure, 

 scattered, and surcharged with synonomy. Without access to a 

 large and well arranged collection, it was hopeless to attempt 

 even much generic subdivision, save in the largest or best known 

 groups of Moths. Hence much work was necessarily of an 

 empirical description, and many of the " difficult " groups re- 

 mained outside the nomenclature. This is now no longer the case ; 

 with these volumes a student of Oriental Heterocera should not 

 find much difficulty in understanding his subject or naming his 

 species. Each genus is illustrated by a typical species, of which 

 one half exhibits the venation, while the other recorded species 

 are also described. 



The author has pursued a synthetic method in his work, but 

 on the merits of " splitting," or " lumping," the pages of ■ The 

 Zoologist' contain no mention. We merely record the comple- 

 tion of a great and successful undertaking; and when it is 

 remembered that the first volume only appeared in 1892, the 

 industry alone displayed is something phenomenal. 



Zoologisches Adressbuch. K.Friedlander&Sohn. Berlin. 1895. 



This * International Zoologists' Directory,' edited and pub- 

 lished by the well-known Berlin firm whose catalogues are always 

 appreciated by scientific workers, will prove a weleome addi- 

 tion to the bookshelf. In these days when zoological work is 

 carried on by so many widely separated students, it is a boon to 

 readily acquire the address of those with whom we wish to 

 correspond. It is equally important to discover the names 

 of those who in far-away localities are interested in the same 

 studies as ourselves, and may be expected to join in mutual 

 assistance. Taken in conjunction with ' The Scientists' Inter- 

 national Directory/ compiled by Cassino and published in Boston 

 in 1892, a mass of information is available which will save much 

 time in these busy days, and serve to increase — where necessary 

 — the number of our correspondents.
