T 1 1HE appearance of the forty-second Yolume of the Zoological 
Record has been a little delayed in consequence of the 
arrangements for provisional amalgamation with the Zoology 
Section of the International Catalogue of scientific literature. 
The following passage, extracted from the Report of the 
Council of the Zoological Society for the year 1905 explains 
this amalgamation as follows : — 
“The annual issues of the ‘Zoological Record’ have long 
been regarded as amongst the most important services to 
Zoological Science rendered by the Society* The magnitude 
of the task has been increasing annually, and in recent years 
the Zoology Volumes of the International Catalogue of Scientific 
literature, issued by an International Bureau under the auspices 
of the Royal Society, have to a certain extent covered the 
same ground. The Council have arranged for a provisional 
amalgamation of the two undertakings for a period of five 
years, beginning with the literature fot* the year 1906, to be 
published in 1907, and hope that the union will lead to increased 
efficiency and economy. The * Zoological Record ’ Committee 
will remain responsible for the scientific side of the work, and 
the conjoint Volumes will be issued with numbers and title 
pages in series with the existing ‘ Zoological Record,’ so that, 
at the end of the period of five years, the Zoological Society 
may resume its independent control, if the amalgamation be 
not successful.”
