tion during the fly period. The exhibition has undoubtedly 

 rendered good service, notably amongst young people, who 

 are keen to note how easily their food can become con- 

 taminated. 



The index series of Mollusca has been re-mounted, and 

 the general series increased by numerous additions. 



The large collection of wet preparations has been syste- 

 matically worked over, and improved in many instances. 

 Additions have been fewer than in former years, owing to the 

 necessity to carefully husband the limited supply of glass jars 

 available, owing to the war. 



Vertebrate Zoology. 



The whole of the collection of bird skins and eggs has 

 been worked through during the year, and a number of the 

 former identified. 



The case of Birds of Paradise has been furnished with a 

 painted background, copied from photographs of the hill 

 country in New Guinea. The painting of a background for 

 the Rhea Case is now in hand. 



To the Mammalia have been added examples of the 

 Clouded Leopard, Kusimanse, and three species of Mongoose. 



Early in the year Lady Jenkinson presented fifteen cases 



of birds. 



Lieutenant J. Dent Young presented the heads and masks 

 of Buffon's Kob, Western Roan Antelope, Senegal Hartebeest, 

 Red-fronted Gazelle, and Eland from the German Cameroons, 

 the trophies having been shot during the recent occupation 

 of the country by the British. 



The collection of plaster casts of skulls and jaws of Pre- 

 historic man has been arranged in a group to illustrate the 

 development of man in time, on the lines laid down in the 

 British Museum Handbook on " Guide to the Fossil Remains 

 of Man."
