 VII. South African Province. 

 The fauna of South Africa, beyond the tropic, possesses few characters 

 in common with that of the western coast, and is more like the Indian Ocean 

 fauna, as might he expected from the direction of the currents. But, 

 together with these it has a large assemblage of marine animals found 

 nowhere else, and the "Cape of Storms" forms a barrier between the 

 populations of the two great oceans, scarcely less complete than the far- 

 projecting promontory of South America. The coast is generally rocky, and 

 there are no coral-reefs ; accumulations of sand are frequent, and sometimes 

 very extensive, like the Agulhas Bank. The few deep sea -shells which have 

 been obtained ojff these banks possess considerable interest, but explorations 

 in boats are said to be difficult, and often impossible on account of the 

 surf. Shells from the Cape are too frequently dead and water-worn speci- 

 mens picked up on the beach. The shell-fish of South Africa have been 

 collected and described by Owen Stanley, Hinds, A. Adams, and, especially, 

 by Dr Krauss, who has published a very complete monograph.* Of 400 sea- 

 shells recorded in this work, above 200 are peculiar, and most of these belong 

 to a few litoral genera. Only 11 species are common to the coast of Senegal, 

 whilst 18 are found in the Red Sea.
