DEPARTMENT OF ZOOLOGY. 89 



The younjD- Malay Elephant has been removed temporarily from 

 the Central Hall, where it was unprotected from dust, to one of the 

 Giraffe cases in the Eastern Corridor on the first floor. 



Whale Room. — To the series of Cetacean casts have been added 

 paddles of the North Atlantic Right Whale (Balaena glacialis) and 

 of a Killer Whale (^Orcinus orca), showing the paddles both before 

 and after dissection ; and the cast of a White-sided Dolphin 

 (Lagenorhynchus acutus). A model of Cavier's Beaked Whale 

 (Ziphius cavirostris) was presented by Mr. A. H. Bishop. 



Study Series. — During the earlier months of the year prepara- 

 tions were made for the return of the part of the collection which 

 had been carried to Exeter for safety during the war. The removal 

 from Exeter to London took place in April. Much material stored 

 temporarily in special places of safety within the Museum was also 

 brought out and unpacked. 



The disturbances due to the war have necessitated re-arrangement 

 of the whole collection. This work was proceeded with continuously 

 throughout the months April to December, and complete order has 

 now been restored in all groups other than the Marsupials. 



It is desirable to save " type " specimens from all unnecessary 

 wear and tear. Therefore, during the work of re-arrangement, 

 all the types of the smaller species have been extracted from the 

 general collection and they have been placed in certain cabinets 

 now reserved exclusively for the accommodation of types. 



The numerous accessions received during the year have been 

 punctually dealt with ; and the usual work of skull preparation, 

 re-making of skins (when necessary), labelling, registering, and 

 incorporating in the collection has been performed. 



The thanks of the Trustees are due to the large number of 

 voluntary workers whose combined efforts have rendered possible 

 the performance of so much work by this section of the department 

 during the past year. Among these vohmteers mav be mentioned 

 Mr. R. C. Wroughton, Mr. T. B. Fry, Miss W. M. Davidson, Major 

 R. E. Cheesman, Captain Kershaw, Mr. Hugh Smith, Mr. Larkin, the 

 Hon. Ivor Montague, Miss C. Janson, Miss Owen, and Miss Stevens. 



In addition to his work in connexion with the Mammal Survey 

 of India by the Bombay Natural History Society, Mr. Wroughton, 

 with the assistance of Mr. Fry and Miss Davidson, has been 

 engaged upon the preparation of a list of the types in the collection. 

 Major Cheesman has given invaluable help in working out the large 

 collections received from Persia and Mesopotamia. Capt. Kershaw 

 and the Hon. Ivor Montague have given much assistance in con- 

 nexion with African mammals. 



A number of casts of Cetacean heads, paddles and valves of 

 the spiracle have been made, The arrangement of the skeletons 

 has been rendered difficult by the want of sufficient cabinet- 

 accommodation. 



Abnormalities and hybrids. — To this series have been added the 

 mounted head of a cross between a male Wapiti [Cervus canadensis^
