South-African Land-MoUusca. 463 



minates in a slender wliip-like form to a fine point. These 

 spines are bunch-like, several branches given off on a thick 

 stem. It is of the type of K. vitalis (pi. xv. fig. 2, 

 Part IT.), but only a dra^ving enlarged to the same size would 

 show properly and clearly the amount of diversity, Avhich 

 as regards spine-distribution, is ^^ : ^. It is impossible to 

 do this, as the number o[ plates would be excessive. 



Burnnp, when sending this species and writing from 

 Tongaat on 18th Jariuaiy, 1909, says : — 



*' The Helicarion sp. ? scarcely agrees with anything that I 

 know (speaking from memory, for I am away from all 

 opportunity of comparing), but it seems nearest to the 

 specimen, which you will now have, sent to me by Mr. Pon- 

 soni)y as No. 3345, which has more than once, but I should 

 sav probably erroneously, been identified as H. corneus, 

 Pfr." 



It is very close to that species, but the anatomy is not 

 quite the same, shown particularly in the radula and 

 sperm atophore.
