Obs. This, according to Mr. Gray, is a vari- 

 ety of his Luponia Algeonsis, "with the teeth 

 more or less obliterated :" but there never have 

 been the slightest vestige of teeth in any of the 

 specimens we have seen, nor are there any irregu- 

 lar ridges crossing the front edge of the columella, 

 which form the distinguishing mark of his genus 

 Luponia. It is an extremely rare and very dis- 

 tinct species from Southern Africa.
