The strie are about twenty-six in number, and extend the whole 
length of the shell, but are quite superficial towards the anterior end 
and gradually become deeper posteriorly, so that the intervening 
spaces are rib-like, some being stouter than others. The posterior end 
exhibits a narrow oblong orifice, set m a pale pink circle which is 
margined with a darker red ring. Outside this, the shell is pale pink 
or whitish. The lines of growth are not strongly marked.
