of the internal anatomy could he uiadc out. There is a broatl, 

 sliort rij;ht shell-lobe (PI. XVI. tig. 3) and a triangular, 

 small left shell-lobe, and a black narrow band bordered the 

 mantle-edge. 



The radula (PI. XVI. fig. 3i) was secured. The central 

 admediau teetli are of uaual form ; the first marginals are 

 nearly evenly bicuspid, becoming tricuspid about the thirtieth 

 tooth, and several have even four cusps and show a serrated 

 edge. 



The formula is 45 . 2 . 9 . 1 . 9 . 2 . 45, or 56 . 1 . 56. 



Jaw with a central projection (PI. XVI. fig. 3 a). 



Major Connolly suggested to me that these small shells 

 were the youiig of M. ,<ijmmetricus, Craven, but the serrate 

 teeth described above are not found in that species. !So far 

 as known, ^1. pumilio differs Irom all the .'species 1 have as 

 yet seen from JSouth Africa.
