The Bulletin of the British Museum (Natural History), instituted in 1949, is issued in four 

 scientific series, Botany, Entomology, Geology (incorporating Mineralogy) and Zoology, and 

 an Historical series. 



Papers in the Bulletin are primarily the results of research carried out on the unique and 

 ever-growing collections of the Museum, both by the scientific staff of the Museum and by 

 specialists from elsewhere who make use of the Museum's resources. Many of the papers are 

 works of reference that will remain indispensable for years to come. 



Parts are published at irregular intervals as they become ready, each is complete in itself, 

 available separately, and individually priced. Volumes contain about 300 pages and are not 

 necessarily completed within one calendar year. Subscriptions may be placed for one or more 

 series. Subscriptions vary according to the contents of the Volume and are based on a forecast 

 list of titles. As each Volume nears completion, subscribers are informed of the cost of the 

 next Volume and invited to renew their subscriptions. Orders and enquiries should be sent to:
