VAGINULID.I:. 481 



" Shape of slug cylindrical, tapering posteriorly. Jaw pale, 

 ribbed. Differs from confusa in its noii-tuberculose sole and 

 different markings and its ribbed jaw. Described from five 

 specimens in the British Museum from Dukhun. 



"Although Godwin-Austen gives but a short description and 

 rather indifferent figure of his type of campestris from Kholabari, 

 and says nothing about the jaw, I think there can be no necessity 

 for considering our Dukhun form distinct from anupcstris, since, 

 so far as we know, there is not any important difference between 

 them. Should the type of campestris be found later on not to 

 have a ribbed jaw, it will be time to propose a new subspecific 

 name for the slugs described above. The discovery of a group of 

 Limacella with ribbed jaw in Asia is very interesting and tends 

 to endorse the opinion that this is not a generic character."
