PREFACE. 



The present volume concludes the account of the Aglyphodont 

 Coluhrine Snakes. 



The collection in the British Museum has received by gifts several 

 important additions since the publication of the first volume. 

 Messrs. Godman and Salvin have deposited a complete series of the 

 species obtained by their collectors and described in their great 

 work on the Fauna of Central America. The contributions to the 

 African Fauna have been scarcely less numerous, the Trustees being 

 indebted to Professor Barboza du Bocage for many specimens of East- 

 African species described by him ; to H. H. Johnston, Esq., C.B., 

 F. J. Jackson, Esq., and others for species collected in various 

 parts of British Central Africa ; and to Dr. J. Anderson, F.E.S., 

 for a remarkably interesting collection of Egyptian Snakes. The 

 collections made by E. W. Gates, Esq., in Upper Burmah contained 

 also a fair proportion of Snakes which were of value as iUustrating 

 the Fauna of this previously little explored region.
