S. Africa. 
Here described from the type of the species from Algoa Bay, an 
example of S. ciliata (Durban, Gilchrist) and two more from Durban, 
165 and 225 mm. long. 
I have compared this species with S. commersoniana, Cant. the type 
species of the genus and I regard them as strictly congeneric. It has 
been stated that in S. commersoniana the right posterior nostril is 
tubular, but the so-called tube has no aperture and the nostril opens 
at its base on the under side.
