the collection. He has not merely regarded these efforts as 

 an official duty, but he has in addition been a generous 

 donor who has frequently supplied funds for the purpose of 

 obtaining specimens. Mr. Miller has thus had at his 

 disposal a collection fairly representative of all parts of 

 Western Europe, and immensely superior to anything that 

 had been thought of before he began his work. 



Marine Mammals (Cetacea and Pinnipedia) are not 

 included in the present Catalogue. For a delinition of 

 " Western Europe " reference must be made to page vii of 

 the Author's Introduction. 



As Mr. Miller is on the staff of the United States 

 National Museum the special and cordial thanks of the 

 Trustees of the British Museum are due to the authorities of 

 the former Institution for the facilities granted to him for 

 carrying through the preparation of the Catalogue, a work 

 which involved a furlough of two years and a half from his 

 usual duties at Washington. 



The thanks of the Trustees are also due to Mrs. Oldfield 

 Thomas and to Mr. E. C. Wroughton for their kindness 

 in undertaking the considerable labour of preparing and 

 verifying the lists of the specimens in the Museum collection 

 after Mr. Miller had made his scientific determinations.
