nates without a beak : the mouth is large and reddifh within ; the whole external fur- 
face of the fhell is perfedly fmooth, and is pf a brown colour, variegated in an ele¬ 
gant manner, with a deeper brown and a grey, and in the whole has fomething of the 
appearance of the plumage of the partridge. 
It is brought to us from the Eaft Indies; and fometimes from the fhores of the 
American lliands. 
Dolium ellipticum longitudinaliter coftatum. 
The elliptic , longitudinally cojlated Dolium . 
This is one of the moft beautiful {hells of this genus: it is about two inches and 
a half long, and a little more than an inch and a half in diameter: the body is, howe¬ 
ver, all the way diftended in fuch a manner, as to give it the perfedt figure’ of the 
others of this genus: the clavicle has five volutions; the lowed: of them, or that next 
the body of the fhell, is large, the others very fmall; and the top pointed; the whole 
furface of the body of the fhell is ornamented with large and elevated ribs; they ftand 
at fiich dtflances, that the fpaces between them are equal to twice or three times their 
own diameters: the colour of the fhell is a deep brown, and it is' variegated with a 
paler b own and wiih white, in a very beautiful manner. 
We have it from both the Eaft and Weft Indies, but the moft beautiful are from 
China. T ' - * : 
Dolium ellipticum Iceve coronatum . 
The fmooth , coronated , elliptic Dolium . 
t ctfttopfatt- 
crotutt. 
This is about three inches in length, and two in diameter; it’s figure is oblong, and 
approaches to an elliptic, but is fomewhat fmaller at each end than in the middle; 
the mouth is long and wide, the- extremity of the fhell a little fplit by it: the clavicle 
is fhort, and obtufe at the extremity ; it has about four volutions, and the lower one, 
as well as the upper edge of the body, are elegantly coronated, or deeply dentated, 
the denticles arilmg into regular, even, and conic points : the • furface .of the fhell is 
tolerably fmooth, but has the marks of many longitudinal lines on it; it’s colour is a 
pale brownifh-yellow. 
We have it from the coafl of Africa, and from the Eaft Indies. 
Doliutn ovatum Iteve^ clavicula deprejfa , ore magno. 
The great-mouthed , fmooth , oval Dolium , with a depreffed clavicle . 
This is a fhell confiderably differing from any of the former j it is about an inch 
and a half long, and an inch in diameter at the larger end, whence it gradually 
grows fmaller to the other, where it is flill very obtufe, and fomewhat fplit by the ex¬ 
tremity of the mouth : the mouth itfelf is of the whole length of the fhell, and isex- 
treamly wide and gaping ; the lip is thin, and the columella has two or three fold¬ 
ings or indentings near it’s lower extremity : the clavicle is depreffed in fuch a manner, 
that it is fcarce vifibie in moft directions of the fhell: the furface of the whole body 
is white, and is elegantly variegated with clouded fpots of yellow. 
We have it from the American fhores. 
Dolium fubrotundum Iceve , ore latiffimo. 
The roundifh , fmooth Dolium , with an ex - 
treamly wide mouth .

This is alfo a very fingular fpecies ; it is about an inch and a half in diameter, mea- 
fured either way; it’s figure approaches to round, but the two extremities of the 
mouth are extended beyond the line of the other parts of the fhell, and fpoil the 
figure, with an appearance of two ,ears. This is one of the moft rounded of this 
whole genus, but in front it appears almoft all mouth: it’s colour is a pale dirty grey 
on the ouffide, and a dead white within. 
We have it on fome of the fhores of the Mediterranean.
