Recent and fossil. The fossil specimens are principally derived 

 from a clay, and exhibit great diversity in size. Some may possibly 

 be primordial chambers of other Lagenidre.

Fossil (common) and recent (rare). The specimens, which are 

 evidently from several sources, present great differences of ap- 

 pearance, some being practically globular, with a produced neck, 

 others pyriform, ranging to attenuate. A few of the fossil specimens 

 show spiral corrugations round the neck. The fossil specimens 

 are all larger than the recent. Millett gives exhaustive references 

 for this widely-distributed form in his Malay paper {supra).
