? Sesara harmeri, var. anodonta, Gude, Jour. MaL vii, 1900, p. 140, 

 figs. 5, 6. 



This species also closely resembles S. ? diplodon, but the aperture 

 is edentulous and the base natter; the spire, too, is rather 

 lower. 



Major diam. (according to Benson) nearly 9, min. 8, axis 

 5^ mm. 



Hob. Teria Ghat, Khasi Hills. 



The shell called S. ? harmeri, var. anodonta, has a descending 

 last whorl near the mouth, whilst H. galea was described as having 

 the last whorl not descending ; the spire, too, in the latter is 

 lower : but it appears probable that the two are identical.
