The smaller dimensions at once distinguish this shrew 

 from hiudei and its allies, while its light underparts, distinctly 

 marked ott" f rom the darker dorsal colouring, render it quite 

 distinct from the jacksoni group.

XI. — On the Eniomostraca of the Albert Ni/anza. 

 By William A. Cunnington, M.A., Ph.D. 



The scientific exploration of the great lakes of Central Africa 

 has never been undertaken systematically ; therefore it is 

 hardly a matter for surprise that in some cases we still know 

 reliitively little of the smaller and more obscure forms of life 

 which no doubt exist in them. In consequence of the very 

 exceptional nature of the fauna of Tanganyika, no less than 

 three British Expeditions (tiie most recent of which I had 

 the honour to conduct) have been sent to investigate that 

 lake. Though Tanganyika was, of course, the first con- 

 sideration, a good deal of attention was paid to other lakes, 

 particularly Nyasa and Victoria Nyanza, while Prof. Moore, 

 on his second expedition, visited Kivu, Edward Nyanza, and 

 Albert Nyanza in addition. It is, however, the fact that 

 Albert Nyanza has received comparatively little attention, 

 and it therefore becomes the moi-e desirable to place on 

 record any additional information concerning it. 



In order to get a knowledge of the plankton organisms, it 

 is clearly necessary to secure a series ot tow-nettings, and, as 

 far as I am aware, this had never been attempted for Lake 

 Albert until the summer of 1907. In July of that year 

 a small quantity of material was obtained by my friend 

 Dr. R. T. Leiper, Helminthologist to the London School of 

 Tropical M-'dicine, who was accompanying an expedition 

 despatched to Uganda by the Egyptian Survey Departmeiit. 

 After collecting two samples, one from the surface and the 

 other from near the bottom in about 30 feet of water,
