The Hiftory of A N I M A L S. 
Cochlea corpore fuhovato , clavicula elata ohtufa variegata. 
The variegated^ oval-bodied Cochlea , with an elate , obtufe clavicle . 
This is aifo an elegant fpeeies: it is about three quarters of an inch in height, and 
near half an inch in diameter : the body of the fhell is large, inflated, as it were, and 
of a figure approaching to oval, but pointed at the extremity of the mouth : the cla¬ 
vicle has three volutions j they are large and rounded, and the fummit is obtufe s the 
ground colour of the fhell is a greyifh-white, and it is variegated with regular fafciae 
or zones of a deep brown. 
We have this in mod of our large rivers, often in ditches. 
Cochlea fufca ore ampliore , clavicula lata acuta . 
The large-mouthed , brown Cochlea ., with an elate y acute clavicle . 
This is about half an inch high, and very little lefs in diameter : the body is of an 
oval figure, and the clavicle is long and pointed at the fummit ; the colour is a dufky 
brown ; the (hell is not fo thick as many of the others, and the mouth is remarkably 
large, and edged by a thin rim, by way of lip. 
We have this very frequent in our brooks and ditches. 
Cochlea clavicula depreffa ore anguflo labiato. ^ 
The narrow and labiated-mouthed Cochlea, with fttfl) 
a depreffed clavicle . "tyttltt* 
This is a very pretty fhell: it is of the number of thofe Cochleae diftinguifhed by 
the name of Nerites, and is not the lead: elegant of that kind; it is about a third of 
an inch in length, and near as much in diameter : the body is of a form approaching 
to oval; the clavicle is depreffed, and is fituated near the fmaller extremity on one fide : 
the mouth is narrow, and has a little lip on each fide; the general colour is a pale 
grey, but it is variegated with a deeper iron grey, approaching to black, in little irre¬ 
gular fpots j and the whole furface is lightly furrowed. 
We have it in fome of our large rivers, particularly in the North of England, but 
it is not common. 
Cochlea ore anguflo labiato cancellata . 
The cancellated Cochlea , with an oblongs 
narrow mouth . 
\yt cancellated, freflj= 
mater jlSedte. 
This is alfo a very beautiful fpeeies j it is about half an inch in length, and nearly as 
much in diameter at the larger extremity : it’s figure approaches to oval, and it’s cla¬ 
vicle is fhort, deprefled, and has but about two volutions: the mouth is narrow, and 
has a lip on each fide, but is not dentated either way: the whole furface of the fhell 
is furrowed with longitudinal lines, and with others eroding them, fo as to form a 
cancellated or kind of let tice-worked furface : the ground colour is a pale grey, almofh 
white, but it is irregularly variegated with blackifb, fometimes difpofed in large clouds, 
fometimes in the form of fmall fpots. 
We meet with this fpeeies in fome of our fwift and clear brooks, and fmaller rivers; 
I have frequently feen it in the trout rivers about Uxbridge, 
Cochlea fubrubens ore anguflo labiato. SDfjt ttD, 
The reddifh Cochlea , with a narrow 5 labiated mouth . W'Uftt 
This is about half an inch in length, and is more than a third of an inch in dia¬ 
meter : the colour is throughout a pale, but not bright, red $ there is a dufkinefs in it, 
which brings it nearer to the colour of a very pale red brick, than to any of the diluted 
purple or bloffom colours: the fubfbnce of the fhell is more firm, and is confiderably 
thicker than in mofl; of the others, and the furface is nearly imooth : there run two or 
three lines, according to the courfe of the volution of the fhell j but they are fo faint.
