Characters. — Shell ovato-globose, sometimes projecting slightly at the apex ; smooth, 

 and without surface-marking. TubeEntosolenian. Walls, thin and hyaline. Length y^th 

 inch or less to 35th inch. 



This is the simplest and, perhaps, the smallest of the Entosolenian Lagence, and 

 holds an intermediate position between the smooth flask-shaped E. IcBvis and the swollen 

 varieties of L. marginata. It was first figured and described by Walker and Boys, but 

 not named by Walker and Jacob in Kanmacher's edition of Adams's ' Essays on the 

 Microscope,' where the specific names given by Walker and Jacob are recorded. It was 

 named by Montagu, ' Test. Brit.,' p. 523. 



Lagena globosa is one of the commonest varieties of the genus. On all parts of the 

 British coast it may be met with in dredged and littoral sands. At the Hunde Islands 

 it has been foimd in material dredged at from thirty to seventy fathoms. In BaSiii's 

 Bay, lat. 75° 10' N., long. 60° 12' W., it seems to be rare, but is of large size — a cmious
