'Turbo tenuijfmus volutiotiibus vix elevatis. 
The very Jlender Turbo , with the volutions fcarce elevated\ 
This is an inch and a half in length, and is the flendereft, in proportion to it’s length, 
of all the fhells of this genus: it’s mouth is oblong and narrow, and it’s fummit finely 
pointed: the fhell confifts of ten or twelve volutions, but they are fo little elevated, 
that it rather appears furrounded with a fpiral line, than really feparated into fo many 
portions: the whole is very thin, and of a tender ftrudture 5 the colour is a very pale 
brown, often whitifh, and the line between the volutions is of a deeper brown. 
We have this in fome of our large ponds, but it is far from common. 
The other fpecies of frefli-water Turbines are, 1. The tall, flender, variegated 
Turbo. 2. The fhort, thick, whitifh Turbo, with indented volutions. 3. The lit¬ 
tle, yellowifh, round-mouthed Turbo. 4. The little, brown Turbo, with a final!, 
detached, round mouth. 5. The larger, round-mouthed, brown Turbo. 
BUCCINA, TRUMPET-SHELLS. 
Buccinum tenuijftmum fufcum ore magno . 
The very thin , brown Buccinum , with a large mouth . 
A"TT"' H E extream thinnefs of this {hell, in proportion to it’s fize, readily diftin- 
guifhes it, without any farther charadferiftic : it is an inch and a quarter long, 
half an inch in diameter in the body, and not thicker in it’s fubftance than a piece of 
the fined: paper: the mouth is very large and oval; the body of the fhell is oblong 
and tumid, and the clavicle has about four volutions: the colour is a brown, with a 
tinge of greenifh or olive. 
It is very frequent in our ponds and ditches. 
Buccinum fubrubens angujlius ore magno . 
The Jlenderer , large-mouthed , reddijlo Buccinum, 
This is an inch long, and about a third of an inch in diameter : the body of the 
fhell is of an elliptic figure, and the clavicle has four volutions, and is terminated by a 
little button : the mouth is very large and oblong 3 the (hell is of a thin and delicate 
ftru&ure, eafily broken, and it’s furface is every-where fmooth 5 it’s colour is reddifh, 
with an admixture of white. 
We have it in fome of our large rivers, where the water is deep, and the current 
but flow. 
Buccinum Jlriatum ore magno ovato . 
The Jlriated Buccinum , with a greats oval mouth . 
This is a very elegant fpecies; it’s length is about three quarters of an inch ; it’s 
breadth is about a third of an inch, and the fubftance of the fhell extreamty thin : 
the body is large, in proportion to the reft; it makes up, in a manner, the whole 
fhell: the mouth is very large and oval; the clavicle is fmall, and has only three volu¬ 
tions ; it terminates in a fharp point: the colour of the (hell is a very pale brown, and 
it’s furface is not fmooth, as in the preceding fpecies, but is very beautifully furrowed in 
a longitudinal dire&ion, both on the body and clavicle, but much more flrongly on the 
body than elfewhere. 
We have it in fome of our large ponds, but not frequent ; it is more common in 
the Weft of England than elfewhere. 
Buccinum angujlius clavicula longiore , ore ovato minore.
