 specimens in the Department of Geology. 



The natural history publications of the Museum have been 

 sent to many Free Libraries and other institutions in Great 

 Britain and Ireland, to Colonial, Indian, and Foreign 

 Museums, Libraries, and Scientific Societies, and to various 

 individuals who have either assisted in the preparation of the 

 volumes or otherwise benefited the Museum ; and several 

 additions have been made to the publications exchange list. 



Having regard to the importance of a study of blood- 

 sucking flies in connection with the dissemination of diseases 

 due to micro-organisms, especially in tropical countries, the 

 Trustees propose to continue the series of publications on 

 these insects, a commencement of which was made by the 

 issue of the Monographs of Mosquitoes and Tsetse Flies. 

 The material available being insulSicient for this purpose, the 

 assistance of the Foreign Office, Colonial Office, and India 

 Office has been obtained in the distribution of copies of a 

 circular letter and pamphlet on the subject to the officials of 

 those departments serving abroad, with a view to the forma- 

 tion of a collection of specimens to serve as the basis of the 

 proposed monographs. Considerable collections of flies, fee. 

 have already been received from all parts of the world, and 

 are being worked out. In the meantime the Trustees^ have 

 published the volume of Illustrations of British Blood-sucking 

 Flies noticed above (p. 103).
