Preface. 
The readers of the present volume, who may be in a position to 
present to the Museum series of specimens illustrating the Economic 
Zoology of any part of the world or belonging to any one of the 
groups recognised in our systematic classification of the subject, 
are requested to communicate with the Director. At present the 
collections, in the Museum, of forms of special economic interest 
require development and additional material.
