Types of radiolata and durbanica in British Museum. 



Hab. NATAL (? pellucens, Wahlberg; radiolata, Nevill). Cato's 

 Creek, Durban ; mouths of Umlaas and Umkomaas Rivers (dur- 

 banica, Burnup). 



Radiolata was described from Zanzibar, durbanica from Natal; 

 the type of the former has not attained fullest dimensions, but 

 seems inseparable from similar specimens of durbanica.
