a female example of Acraca medea> from Prince's Island in 

 the Gulf of Guinea. This interesting butterfly, which is 

 extremely rare in collections, is considered by Mr. H. Eltring- 

 ham to be an island form of A. egina. 



(3) Thirteen butterflies from different localities in the north- 

 east of German East Africa were received from the Berlin 

 Natural History Museum. The collection consisted of a 

 valuable scries of Acraeinae i together with one example of 

 the extremely interesting Nymphaline butterfly, Catuna 

 sekoratia, new to the Hope Collections. 



A very fine male example of Tiruntala (Melindd) morgeni, 

 from the Ja River, Cameroons (1909), was presented by 

 H. Eltringham, Esq., M.A., New College. This is only the 

 second example in the Department of this most interesting 

 mimetic butterfly, the previous specimen having been pre- 

 sented a year or two ago by the Hon. Walter Rothschild, 

 F.R.S. The great interest of the specimen is that it shows 

 the influence of the local Ethiopian Danaine pattern, as 

 represented in the genus Amaurts, upon an Oriental invader, 

 arriving from the Hast and finally penetrating to the West 

 coast. The invader has now given rise to three different 

 species, of which the eastern, T. formosa, is still Oriental in 

 appearance, the central species, T. mercedonia, has become 

 much darker, while the third, T. morgeni, from the West 

 coast, has, superficially, precisely the appearance of a black 

 and white African Amaurts. 



A set of 12 Acraeas from Ukerewc Island, in the SIC. 

 of the Victoria Nyanza, and 4 from Kigonsera, near the 

 NE. shore of Lake Nyasa, were, through the kindness of 

 H. Eltringham, Esq., M.A., New College, presented by Herr 

 J. N. Ertl. 



A series of 6 examples of the Pierine butterfly EucJdoc 

 char Ionia t from Lanzarote, Canary Islands (300 ft.), was pre- 

 sented by E. A. Elliott, Esq., F.E.S., F.Z.S. The specimens 

 were captured at Haria in 1903 by Fairfax Prevost, Esq. 

 The occurrence of this African form in the Canary Islands 

 is of great interest.
