JHab. Port Elizabeth. 



Mr. Ponsonby has shown me a single valve, much worn, 

 and quite colourless, of a much larger specimen, measuring 

 35 x 25 millim. The smaller specimen, which I have taken 

 for the type, has a few faint markings like those of S. scripta. 

 The general character of the shell is more like S. menstrualis, 

 or excavata, but of a more oblong-oval form.
