3. On two new Species o£ Copepoda from Zanzibar. 

 By Gilbert C. Bourne^ M.A. 



[Eeceived December 13, 1892.] 



(Plate VI.) 



So little is known of the Entomostraca of Africa, that I gladly 

 availed myself of the opportunity of examining a portion of sandy 

 mud, brought by Mr. Finn, of Brasenose College, Oxford, from the 

 neighbourhood of Zanzibar, which was kindly supplied to me by 

 Mr. P. E. Beddard. 



The result of my search was rather disappointing, as I only 

 succeeded in finding a few minute Copepoda, belonging to two 

 species, which I now describe. Of these one is doubtfully a 

 new species, being closely allied to Cyclops orientalis, Uljanin, 

 from Turkestan. The other is a well-marked species of Can- 

 tliocamptus. 



In publishing a description of these two forms, T may take the 

 opportunity of pointing out how much may be done by travellers 

 and explorers in Africa in the matter of collecting freshwater 

 Crustacea. These forms are easily collected and preserved, and 

 from their generally minute size are easily carried. It is probable 

 that the great lakes of the interior have a peculiar and interesting 

 Crustacean fauna which would well repay collection. Those who 

 have read Weismann's charming essay, ' Das Thierleben im 

 Bodensee,' will recognize what a wide field of study is here open 

 to the traveller and collector.
