VO LV ARIA acutiuscula. 
TAB. CCCCLXXXVII. 
Spec. Char. Nearly cylindrical,, with a pointed 
apex ; spire concealed ; striae numerous, com- 
posed of squarish punctums ; plaits upon the 
columella variable. 
Syn. V. acutiuscula, G. B. Sowerbj/’s Genera of 
Shells ( Genus Volvaria , fig. 3). 
Well distinguished from both the French species by 
the aperture being so prolonged beyond the apex of the 
spire as to conceal it within a small pit ; it is also less 
cylindrical, being a little contracted towards both ex- 
tremities; the plaits upon the columella are usually 
about four, but often irregular in size as well as variable 
in number. 
This pretty shell has hitherto only been found in Bar- 
ton Cliff : we are indebted to several friends for speci- 
mens : it does not appear to be rare. It is rendered 
more interesting by the reflection, that it is very nearly, 
but not precisely, like its congeners found near Paris : 
similar facts, we have reason to believe, will prove of 
more frequent occurrence than has been suspected.
