The Echinoderm Fauna of South Africa. 223 



places on all this reach of shore where collections of echinoderms have 

 been made. As a matter of fact we know nothing of the western 

 coast of South Africa from Cape Town to Mossamedes, yes even to 

 the mouth of the Congo, excepting only Saldanha Bay and Angra 

 Pequena Bay. It was only at the earnest request of Dr. Peringuey 

 that I consented to include Mozambique, for so far as the echino- 

 derms are concerned that region is distinctly Indo-Pacific and has 

 a very different fauna from that of Natal and Cape Colony. I 

 think this will be clearly shown in the following discussion of the 

 South African fauna. 



For the privilege of preparing this report and for the honour 

 done me in entrusting these valuable collections to my care, it gives 

 me pleasure to express my sincere thanks to Dr. Peringuey, who 

 has spared no pains to assist my work in every possible way.
