Vertigo japonica \\. sp. 



Shell minute, oblong, about equally obtuse at both ends; brown, 

 nearly smooth. Whorls 5, parted by deep sutures, the last whorl 

 tapering downwards, impressed by a deep furrow terminating above 

 the middle of the outer lip. Aperture irregularly ovate, contracted 

 by four teeth : a long parietal lamella, a strong columellar lamella
