The following Notes and Oeservations were written by Dr. LiJ^er in d 
Copy of this Work ( conlifting chiefly of Proof Plates) now in the 
PolTeflion of Mr. Ingham FQrfiery Merchant in London^ by whom it. 
was mofl: obHgingly communicated to the Editor. A. D. 1769.

572. 23. /T^HIS, probably, is a Sea Shell ; having feen Barnacle Shells adhere to it, and therefore 
\_ is to be removed from this Tribe. ( N. B. In fome of the firjl Impreffions it was flaced 
among the Land Snails. )

65. 63. This Shell is very thin and brittle -, of a Stone Colour : the Navel or Hollow in the Centrc 
is deep, and it rifeth up high from the Edges, in which it very much difFers from all the reft 
of this Tribe. The Shell is circumfcribed by a very fliarp and prominent Edge, the under- 
neath by a Wreath not quite flat, but a little convex, and are four in Number. It was fent 
from jamaica by Dr. Sloane. 
158. 13. This Shell is very thick and ponderous, very fmooth on the outfide and of a yellowifli green 
Colour, not unlike the frefli-water Mufcle Shell, poflibly it may be owing to thatTribe, tho' 
of an uncommon Make and Figure, I never faw but this one Shell and that in Mr. C.'s 
CoUeaion.

165. 2. This Scallop is much lefs than the former ; otherwife it is, in many Things, much like it, 
that being ever of a Stone Colour ; it differs in that it is rcdifli and curioufiy marbled, both 
about the Bottom and on the upper Part of thc biggei Shell : aifo it agrees in the Hollownefs 
of the leflTer or under Shell, fo as to be diflied oucwardly; in the number of Ridges, which 
are in this about fourteen ; alfo in the oblique Notches upon the Hinge ; which yet in this 
feem to be more than in the former, as is exprefl^ed in the next Draught. T. 1 66. 
i65, 3. In this alfo the Channells are fmooth and without ftreaked, whereas the Channells of the 
Englifli Shell are as thick and deep ftreaked as the Ridges. Again the Sides of thefe Ridges 
in this Shell are more at right Angles ; whereas in that they are flatter. 
167. 4, This is the biggeft Scallop I have feen it is alfo thick and heavy; it was of a bue clay 
Colour, but it was apparently old and weather beaten, fo that the natural Beauty of the living 
Fifli was periflied. It is but fliallow. It has but ten Ridges ; but the Furrows betwixt them 
are very deep, and cut down almoft at right Angles ; at the very Head of the Shell, betwixt 
the Eares, the Furrows are very deep, though fmall, and end all in a Foint very elegant ; 
whereas in the two former Shells the Heads are fmooth, and the Ridges and Furrows in that 
Part are almoft obliterated. The Ridges and Furrows here are all of them curioufly ftreaked, 
A good Inch from the Bottom of the Shell the Ridges and Furrows become fuddenly of an- 
other Fafliion and Grain, and are, as it were, tranfverfly waved and fmooth. 
I nevcr faw but two of thefe, and they were both bigger or upper Shells of the Scallop. 
N.B. That is a Fault in the Engraver to have made the Ridges towards the Head a littlc 
crooked, whereas they lie all very ftrait and run to a Point. 
170. 7. This is theonly Scallop of the Kind that I have feen in Mr. C.'s Colleiflion. 
It is deep and hollow ; thin and light ; the Ears exadly alike ; it hath eighteen Ridges, 
all which are of a dark heavy Colour almoft black ; the Furrows are all white, and both the 
Ridges and Furrows are fmooth and not at all ftriated ; the Extremities of the Ridges are 
notched very remarkably, not enough expreffcd in the Figu.re. 
171. 8. This is a white Shell (I never faw but one of them in Mr. Charlton'% Colleftion) fhallow, 
with four large Rifings or Ridges, befides other fmaller : on the left Hand the Ear had under 
it a Row of fmaU Teeth that were in a Manner wholly dcfaced.

174. II. This Shell is rare and few of them are to be met with in the Cabinets of the Curious; 
It is very fiat and hollow, and yet the one Side is much flatter than the other, efpecially at the 
Head, wjiich I have cauled alfo to be drawn from ^ very perfed pair : (See 175. 12.) This 
Scallop is more Long than Broad having thirteen or fourteen Ridges very round and rifing ; 
the Ears are on both Sides large, but not altogether alike, being a Thought larger on the right 
Hand : we fpeak of the uppermoft or bigger Shell which is now figured in this Plare. 
Moft that I faw were whke, but the neithermoft Shell of one Pair was fpotted with a dark 
hair Coiour.
