a map of distribution of the species are also shown. The work in 

 connection with this case was carried out with the help of Major 

 E. E. Austen, D.S.O. (Entomological Department). 



The original models illustrating the life-history of the 

 malarial parasite have been replaced by a better series, which 

 was exhibited at the Ghent Exhibition in 1913. Opportunity 

 was taken at the same time to change the old and faded labels 

 for new ones. 



Captain Sir David Wilson-Barker's observations on the flight 

 of the Albatros have been illustrated by a chart (including 

 detailed and explanatory labelling) which has been framed and 

 placed on exhibition in Bay III. 



The labels of the Schistosomiasis (Bilharziasis) exhibit in the 

 Hall have been revised, and a drawing has been inserted in the 

 series to replace a vague and over-exposed photograph. 



The Amphioxus case in Bay Y. has also been thoroughly over- 

 hauled and renovated. 



The preparation of an Index-series, to serve as a general intro- 

 duction to the contents of the Museum, has occupied much time. 

 The first case, containing part of this series, should soon be ready 

 to be placed in the Central Hall.
