H A L I O T I S, 
T^HE Haliotis is a fim pie fhell without any hinge, and formed all of one piece, of 
JL a deprefied figure, very patent at the mouth, having an approach to the fphal 
form at the fummit, and having feveral perforations on the lateral part of the difL 
The animal inhabiting this (hell is a limax. 
It has obtained the name Auris marina, from it’s refemblance to the figure of an 
ear ; fome of the old writers, as Aldrovand and Rondeletius, have arranged it with the 
limpets, and called it Patella fera ; and fome others have called it Ormus. Lifter has ar¬ 
ranged it among the turbinated fhells, becaufe of the fpiral turn at the fummit ; but 
this is by no means fufficient to give it a place among thofe fhells. 
Haliotis margine cequali^ foraminibus feptem. 
The Haliotis , with an even edge , and with feven holes . 
This is a very large fpecies; it’s length is often five inches, it’s breadth nearly three, 
but it’s height, at the utmoft, not more than three quarters of an inch : it’s figure ap¬ 
proaches irregularly to an oval; the end, where the fpiral turn is placed, is the largeft * 
the other a little fmaller ; the back or hinder edge is thick, and is turned fo as to form 
a kind of lip ; the other or anterior edge is thin, fimple, and even : the upper furface 
of the (hell is of a brown colour, rough and uneven, with a kind of undulated lines; the 
part toward the head is thickeft, and the fpiral turn fhort and deprefled : along the back 
part of the {hell, near the thicker edge, there are placed a feries of holes or perforations, 
of a roundifh figure ; the number of thofe which are open is feven ; there are the 
marks or veftiges of more toward the top of the {hell, but they are clofed up, and 
partly obliterated : as the fhell grows in length, there are from time to time new holes 
formed in the extended part, and for every one of thefe there is one of the old ones fil¬ 
led up, or obliterated, the number nature allots to be open being only feven: the in- 
fide of the fhell is of a beautiful pearly hue, variegated with a great many bright 
and elegant colours, as viewed in different directions to the light; and, the outer coarfe 
cruft of the upper furface being eaten off with acids, that exhibits the fame pearly 
hue, with the fame variety of colours : there are very frequently found a kind of 
roundifh protuberances, in the form of warts, adhering to the infide of the fhell, which 
have much the appearance of pearls, and are fometimes cut out by our workmen, and 
ufed in ornaments: real pearls are alfo fometimes formed in this fpecies. 
It is frequent in moft parts of the world; Europe and America both produce it, 
but it is no where fo abundant as in the Eaft Indies. 
Haliotis angujlior margine undulata , foraminibus o&o. 
*The narrower Haliotis , with an undulated edge , and 
eight holes . 
This is a very beautiful fpecies: it grows to three inches in length, and not more than 
an inch and a quarter in breadth in the largeft part; it’s height is nowhere half an inch: 
the head is large and thick, and the fpiral turn is very beautiful and fair; the back of 
the fhell forms a regular and even lip, and the anterior edge is thin and undulated : 
the infide of the whole fhell is of a beautiful pearly hue, with fine variegations of co¬ 
lours ; the outfide is fmooth, but fomewhat undulated from the fpiral turn, and is of 
a greenifh colour, variegated with a brownifh red : there is a long feries of holes on 
the back edge of the fhell, and eight of them are always open ; the others toward the 
head are clofed. 
It is found on the rocks on the Malabar coaft, and is walked afhore in fome other 
parts of the Eaft Indies; we have alfo had fome very fine ones from the ifland of Or¬ 
mus, in the Perfian Gulph.
