TURBINES, S C R E W-S HELLS. 
A L L the known land Turbines are very minute. 
Turho angufia fufca ore elongato. 
\The /lender-, brown "Turbo , with a narrow , oblong mouth . 
This is about a quarter of an inch long, and is hardly a fourth of if s length in dia¬ 
meter at the bottom : from this part it grows gradually fmaller to the fummit, where 
it is terminated by a very fharp point: the mouth is narrow, and is carried up a great 
way into the firft volution of the fhell; the whole fhell confifls of about eleven of 
thefe, and is fomewhat deeply furrowed by the fpiral line, which feparates them : the 
colour of the whole is an elegant pale yellow, but the lining of the mouth is white. 
We have it in fome of our woods about London, among the damp mofs, about the 
flumps of decayed trees. 
Turbo brevior volutionibus Jlriatis . 
The Jhorter Turbo , with the volutions all ftriated. 
This is not longer than a full-grown barley-corn, but it is thicker than the genera¬ 
lity of the Turbines, in proportion to it’s length : the mouth is of an oval figure; the 
largefl part upwards, which is the contrary of the mouth of the preceding fpecies ; the 
top is obtufely terminated; the whole (hell is formed of about twelve volutions, not 
very diflindly feparated, but all of them finely flriated in a fpiral direction: the co¬ 
lour is an elegant chefnut brown. 
We have it in fome of our old hedges, among the damp mofs that grows about the 
flumps of the trees, and in the ditches. 
Turbo angujlior margine volutionum peEUnata, 
The /lender Turbo } with the edge 0/ the volutions peEUnated. 
This is the mofl elegant in it’s flrudure of all the land Turbines; it is about a fixth 
of an inch in length, and is hardly a third of it’s length in diameter : the mouth is 
narrow, of a form approaching to oval and labiated ; the whole fhell confifls of about 
twelve volutions, and the rim or edge all the way is deeply and elegantly denticulated, 
or rather pedinated, the denticulations being deeper than what are ufually expreffed by 
that name: the colour is a dufky grey, but toward the top it is whidfh. 
I met with this fpecies in confiderable abundance fome years fince, among the great 
tree lungwort, on the old beeches, in Charlton-forefl in Suffex $ elfewhere I have not 
feen it. 
Turbo volutionibus tumidis ore fubrotundo. 
The round-mouthed Turbo, with tumid volutions . 
This is about an eighth of an inch in length, and nearly a third of it’s length in 
diameter: the mouth is round, and has no lip furrounding it j the fhell is formed of 
about nine volutions; they are elevated and tumid, and the line between them is confe- 
quently funk very deep : the colour of the whole is a yellowifh-brown, only toward the 
top, or fmaller extremity, the brown wears off, and the colour more approaches to a 
whitifh-yellow. 
This fpecies alfo I met with in Charlton-forefl, and have not feen it elfewhere. 
The other fpecies of land Turbo’s are, 1. The very flender, yellow Turbo. 2. The 
very (lender, whitifh Turbo, with pundated volutions, and a narrow mouth. 3. The 
flender, brown Turbo, with a round mouth, and a very (hallow line between the vo¬ 
lutions. 4. The fhort, thick Turbo, with a very fharp point, and a long flit in the 
place of a mouth. I am apt to believe more fpecies will be difcovered 5 thefe have been 
principally of my own finding in damp woods, while I was invefligating the moifes.
