Specific Characters. — Shell sinistral, elongate, rather solid; whorls 9 or 10 (?), 

 slightly convex, regularly tapering ; ornamented by numerous fine, well-marked 

 and flexuous costae in the lines of growth; base of the last whorl angulate and 

 contracted below ; suture distinct, oblique ; peristome continuous ; mouth sub- 

 quadrangular ; outer lip slightly projecting. 



Dimensions. — L. 10 mm. B. 8 mm. 



Distribnfioii. — Not known living. 



Fossil: Coralline Crag: Sutton. Amstelien deposits: Amsterdam 

 (Lorie). 



Eemarhs. — This species is represented by a unique and incomplete example, 

 now in the British Museum (Natural History), obtained by Wood from the 

 Coralline Crag of Sutton. It differs from any British form. Dr. Lorie believes 

 that he has obtained several specimens of it from a deep boring at Diermerburg, 

 near Amsterdam, at a depth of about 230 metres in beds which I regard as 

 Amstelien. I have not seen these fossils, but if they are correctly identified it 

 brings down the existence of this species in the Anglo-Belgian basin to a much 

 later date than that of the Coralline Crag.
