DescHption. — Test elongate, clavate or fusiform, with a long neck 

 at the oral end and an elongation of the test somewhat variahle in 

 length at the ahoral end; surface smooth, cross section nearly cir- 

 cular; wall thin and transparent; aperture nearly circular, at the 

 end of the neck, often with a phialine lip. 



Length up to 1 mm. 



Distribution. — This species is common about the British Isles, as 

 the above references show, and material which I have had from 

 stations mainly from off the coast of Ireland. It has occurred rarely 

 in the AJhatross western Atlantic collections, single specimens from 

 two stations being all that I have found. 



Lagena clavata — material exawiined.
