PREFACE. 



r I 1HE first volume of the Catalogue of the Library of the British Museum (Natural 

 History) was published in 1903, and, like the succeeding four volumes, 1904-1915, 

 it was prepared by Mr. B. B. WOODWARD. The time has come for the issue of a Supple- 

 ment, the first part of which, forming Vol. VI of the complete series, has been compiled, 

 with some clerical aid, by the same author, on the lines laid down in the Introduction to 

 Volume I. 



During the progress of the work Mr. WOODWARD has received assistance from the 

 following representatives of the several Departments : Zoology Dr. W. T. CALMAN, 

 F.R.S. ; Entomology Mr. J. HARTLEY DURRANT, who has contributed many valuable 

 bibliographical notes, particularly under the headings Godart and Herrich Schaeffer, in 

 the present part ; Geology Dr. F. A. BATHER, F.R.S. ; Mineralogy Dr. L. J. SPENCER ; 

 Botany Mr. A. J. WILMOTT, B.A. ; as well as from Mr. BASIL H. SOULSBY, M.A.,.the 

 present Librarian in the General Library. 



A special acknowledgment is due to Mr. C. DAVIES SHERBORN, who has continued 

 to place the valuable bibliographical data collected by him for the "Index Animalium" 

 at the author's disposal.
