PREFACE. 
In conformity with this announcement our Volume for 
1906 will be a joint production of the International Catalogue 
organisation and of the Record Committee of the Council of 
the Zoological Society of London. It will be continued on the 
same general lines as the later Vplumes of the Zoological 
Record, and will be made uniform with the Volumes of the 
International Catalogue by similar typography and other 
details. 
The Editor of the Record anticipates that the hope of 
greater efficiency expressed by the Council in the paragraph 
quoted above will be realised. 
The usefulness of the Record hitherto has been chiefly due 
to the amount of work carried out by the Recorders. Of late 
years their task has been too great. Under the new arrange- 
ment it should be considerably reduced. And as we may 
anticipate that the expert knowledge that has been placed at 
the disposal of the Record Committee will still be continued, 
we have good reason for sanguind anticipations. 
It is intended that the Annual Volume shall equal the 
present Zoological Record in arrangement and facility of use, 
and that it shall by the efforts of the Regional bureaus of the 
World be made superior in completeness to anything that has 
yet appeared. 
The Volume will appear at the customary period of the 
year; and qo change will be made in the arrangements by 
which the Subscribers to the Zoological Record receive, and 
pay for, the Annual Volumes.
