he observed that ‘‘it is remarkable that this characteristic 
species, which had been so long considered as peculiar to 
the shores of the Mediterranean, has been lately found 
by M. lAbbé Maillard at Beauvais, in the north of 
France.”

[=Butimus acutus Jeffreys}. 
Long, conical, whitish, with a single dark band below the peri- 
phery; whorls 8-93 zmdz/icus very slight. A.15mm.; B. 5mm. 
In Great Britain this is a strictly littoral species, ex- 
tending interruptedly from extreme north to south. In 
Treland, where it is also very widely distributed, it is found 
in inland situations a hundred miles from the sea. It 
inhabits grassy cliffs, downs, and sand-hills. 
There is in this species an internal calcareous body, 
much resembling a miniature continental sabot, which is 
probably analogous to the ‘dart sac’ of other Helices. 
This little object can be extracted and mounted on black 
card in a similar manner to the darts already described. 
All the vars., except a/ba, are fairly common and gener- 
ally distributed; var. a/éa is found plentifully at Bundoran.
