THE BULLETIN OF THE BRITISH MUSEUM 
(NATURAL HISTORY), instituted in 1949, is issued 
in five series corresponding to the Departments of the 
Museum, and an Historical series. 
Paris will appear at irregular intervals as they 
become ready. Volumes will contain about three or 
four hundred pages, and will not necessarily be com- 
pleted within one calendar year. 
In 1965 a separate supplementary series of longer 
papers was instituted, numbered serially for each 
Department. 
This paper is Supplement No. 5 of the Geological 
(Palaeontological) series. The abbreviated titles of 
periodicals cited follow those of the World List of 
Scientific Periodicals.
