fome minute Britifh Shells . 
A fourth is a minute fhell of the Ti/rfo kind. 
It ftrongly refembles the deprefled Helices ; but its circular 
mouth forbids its being ranked in that genus . 
It confifts of four cylindric or rounded volutions, of nearly 
equal height on one fide, but funk or umbilicated on the other. 
Thefe volutions are tranfverfely furrounded with numerous 
fharp-edged membranaceous rings, which are very fragile and 
deciduous. The mouth, when perfect, is bordered with a 
comprefled eredt margin. The colour of the fhell is uniformly 
brown. 
It may be named, 
Turbo ( [helicinus ) tefta depreffo-plana, hinc umbilicata, 
anfradtibus 4 torofis, annulis numerofis acutis membra- 
naceis cindtis. 
The fine-ringed Turbo. 
The figures herewith exhibit both fides of the fhell, in its 
natural and magnified ftate.

No author, that I know of, lias defcribed it. 
It was found near Buliftrode, upon bare ftones, in the 
fpring feafon, and at other times in moifl: weather. 
The fifth and lajl fhell I have to mention, is a fmall thin 
oblong comprefled Patella , of a horn colour, about a quarter 
.of an inch long, and one- tenth of an inch wide, having a 
pointed vertex nearefl: to the. lower end, turned downwards, 
and leaning to one fide. 
It may be called^.
