The scorpiol'auna of British East Africa is closely allied 

 to that of German East Africa and constitutes together with 

 the fauna of the northern partis of the latter a transition to 

 the fauna of NE Africa, of Somaliland and of Abyssinia. The 

 south-african genera and species are almost wholly absents 

 in the scorpiofauna of this country; for instance, the genera 

 Opistophthnlmus and Hadogenes are not represented in the 

 Jauna of East Africa; Opisthacanthas is represented perhaps 

 only by one species, 0. fischeri, inhabiting the northern parts 

 of German East Africa. Bahycurus centrurimorphus and Lychas 

 asper are species of a wide distribution and occur also in 

 West Africa; several species are essentially northeast afri- 

 can, somalian, in their affinities: WdiXw^l j—Bathus polystictiis, 

 Parabuthus liosoma, Pundinas pallidus, and, perhaps also P. 

 gregoryi. Uroplectes fischeri, Jomachiis politus, Buthus emini, 

 Lychas burdoi have a very wide area of distribution in East 

 Africa; several species are hitherto found only in British 

 East Africa and partly in the neighbouring parts of the Ger- 

 man colony, namely Porabiithus pallidus, Lychas obsti, Odon- 

 turus dentatus and Babycwnis toituetisis.
