The radula is elongately quadrangular, consisting of about 

 35 to 50 transverse rows of teeth, meeting at sharp angles in the 

 middle line ; there are about 80 — 100 teeth in each row. They are 

 all of a similar shape, pyramidal, sharply pointed and attenuated in 

 front, gradually becoming wider and terminating with an obtusely 

 rounded base. The middle tooth is slightly contracted below the 

 middle, it is symmetrical ; the laterals are gradually more bent out- 

 wards on either side and possess on the outer side near the point, 

 a rounded and angular projection ; the angle appears to be directed 

 posteriorly ; the outermost teeth are quite simple. 



The teeth of S. discoidalis and conjangens are exactly similar to 

 those of calias, only comparatively smaller. The jaw and radula 

 of S. forabilis were not examined.
