In addition to the above collections, presented as a whole, 

 the Hope Department has been rapidly accumulating extensive 

 collections made in recent years in various parts of the world, 

 especially Africa. The principal naturalists who have con- 

 tributed material from this continent are : C.N. Barker, 

 F. N. Brown, H. A. Byatt, G. D. H. Carpenter, W. A. Lam- 

 born, G. F. Leigh, G. A. K. Marshall, the late A. D. Millar, 

 S. A. Neave, the Rev. K. St. Aubyn Rogers, C. F. M. Swyn- 

 nerton, and C. A. Wiggins. The chief areas represented by 

 the collections of these naturalists are : Natal, Rhodesia (both 

 North and South), British .Central Africa, British East Africa, 

 Uganda, and the Lagos district of West Africa. From these 

 parts the Hope Collection probably possesses more extensive 

 and more instructive material than any other museum. A large 

 part of the African material has been specially collected in order 

 to throw light upon bionomic problems, such as Mimicry, \\'arn- 

 ing Colours, Protective Resemblance, and the alternation of 

 seasonal forms. Great collections from many parts of the world 

 have been presented by Herbert Druce, Dr. G. B. Longstaff, ' 

 and Commander J. J. Walker, from Borneo by the late R. 

 Shelford, and from Majorca by the Professor, A. H. H.\:^i:\i, and 

 W. Holland. 



It is only possible to mention specially the principal help 

 that has been generously given in the labour of working out the 

 University Collection. Dr. F. A. Dixey, H. Eltringham, and 

 the late R. Shelford ha\'e made their respective groups, the 

 PierincB, the Acrœinœ, and the Blaiiidcc, the most perfectly 

 arranged and instructive of any in existence. Dr. Longstaff 

 has not only worked out his own material, but has also with great
