[Plate I.] 



Family Achatinidae, von Martens, 1879. 



In dealing with the members of this family I would explain 

 that all my measurements are taken with the shell lying fiat 

 on its back, aperture upwards, and that the length of last 

 whorl is the distance between the extreme base of the 

 aperture and the centre of the suture immediately above it. 

 Although not strictly accurate, the term length of whorl 

 denotes the vertical distance between sutures, in order to 

 avoid any confusion with the breadth of spire. 



Subfamily Stenoqyrinm^ Fischer, 1883. 

 Genus PsEUDOGLEssuLA, O. Boettger, 1892. 



Thin, corneous shells, more or less elongate, sculptured to 

 the apex with prominent transverse strise. 



Subg-enus Pseudoglessula, s. s. 

 Shell elongate, imperforate.
