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 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 yery extensive, like the Agulhas Bank. 
The few deep-sea shells which haye 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 haye been collected and described by Owen Stanley, 
Hinds, A. Adams, and especially by Dr. Krauss, who has
