Description. — Test typically subglobose, very slightly longer than 

 broad, the neck fairly long and cylindrical, ornamentation consisting 

 of numerous, 14-18, distinct elevated costae, running from the basal 

 end of the test to the apertural end, and a few of them often con- 

 tinued in a spiral manner the length of the neck itself. 



Length up to 0.35 mm. 



Distribution. — About the British Isles this seems to be a very 

 common species, but specimens which can be referred to the typical 

 form seem to be very rare from the western side of the Atlantic. 

 There are numerous records of its occurrence from many parts of 

 the oceans, but specimens are not usually figured and it is difficult 

 to say what the distribution of this typical form may be. Many 

 things have been placed under this name which are very different 

 from the typical western European form of the species.

Description. — Variety differing from the typical in having the 

 apical end drawn out into a stout spine, the apertural end with a 

 tapering cylindrical neck with a phialine lip, usually without other 

 ornamentation, body of the test with numerous longitudinal costae, 

 as in the typical form.
