Rare. Two specimens only of this pretty Odostomaa were 
obtained in the material from Fillyside. 
As a fossil this appears to be a rare species, and does not 
appear to have been previously recorded for Scotland. 
All the Odostomia here recorded are found living, and 
generally distributed throughout the British Islands,
