DescHption. — Test flask-shaped, pyriform, keel with compara- 

 tively few, large, remote tubulations, body of test not greatly com- 

 pressed; surface ornamented with coarse longitudinal costae run- 

 ning the length of the body of the test. 



Length 0.35-0.50 mm. 



Distribution. — Most of the records for this variety are from the 

 region of the British Isles and the Mediterranean. Although speci- 

 mens referred to the typical form of the species have occurred in the 

 Albatross dredgings, none of them showed the striations character- 

 istic of this variety.
