 characters in common with that of the western coast, and is 

 more like the Indian Ocean fauna, as might be 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-pro- 

 jecting 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 off 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 specimens 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
