Description. — "Test lanceolate, very elongate, strongly com-

 the greatest breadth occurs; primordial chamber spherical, ele- 

 vated, mucronate, and the surface marked by three sharply defined 

 ribs; surface of shell marked by numerous fine longitudinal lines, 

 running nearly parallel tO' the lateral edges ; septa distinct, slightly 

 raised externally as ridges; aperture normally ro-und, terminal. 



"Length, 2.6 mm. ; breadth, i mm. 



Reimarks. — "This species is very closely allied to the European
