Of the Pacific species at the Cape of Good Hope not hitherto recorded from that 

 locality, the Challenger collected Lovenia elongata; but by far the most interesting 

 species collected at the Cape by the Challenger were Spatangus raschi, Echinocardium 

 Jlavescens, Brissopsis lyrifera, and Schizaster fragilis, which thus far, axe found to be 

 eminently Atlantic sjaecies characteristic of the deeper water, and cropping to the surface 

 as in the continental range in Eastern North America, Brazil, West Indies, and Western 

 European seas. 



The assemblage of species at the Cape of Good Hope is most peculiar, it is the 

 meeting of the western boundaries of the African-Indian-Pacific and of the Indo-African, 

 the southern boundary of the Atlantic, and the northern extremities of the southern 

 Ocean faunse, and it has no species characteristic of its own in the contiaental or abyssal
