The following Notes and Observations ivere written by Dr. Lister in a copy of this 
ivork (consisting chiejly of proof plates') in the possession of Mr. Ingham For ster, 
merchant in London, by whom it ivas communicated to Dr. Huddesford, A. D.

This, probably, is a sea shell; having seen barnacle shells adhere to it, and there- 
fore is to be removed from this tribe. (N. B. In some of the first impressions it 
was placed among the Land Snails.) 
Trochilus Monspessulanus triplici aspectu. 
This shell is very thin and brittle; of a stone colour; the navel or hollow in the 
centre is deep, and it riseth up high from the edges, in which it very much differs 
from ali the rest of this tribe. The shell is circumscribed by a very sharp and 
prominent edge, the underneath by a wreath not quite flat, but a little convex, 
and are four in number. It was sent from Jamaica by Dr. Sloane. 
This shell is very thick and ponderous, very smooth on the outside, and of a yel- 
lowish green colour, not unlike the freshwater muscle shell: possibly it may be 
owing to that tribe, though of an uncommon make and figure. I never saw but 
this one shell, and that in Mr. C.’s collection. 
Pecten maximus, circiter quatuordecim striis admodum crassis et eminentibus, et 
iisdem ipsis striatis insignitus. Lister. de Coch. Marinis Animalium Angliae, 
tit. 29. 
This scallop is much less than the former, othervvise it is in many things much like 
it, that being ever of a stone colour ; it differs in that it is reddish, and curiously 
marbled, both about the bottom and on the upper part of the bigger shell: also 
it agrees in the hollowness of the lesser or under shell, so as to be dished out- 
wardly; in the number of ridges, which are in this about fourteen; also in the 
oblique notches upon the hinge, which yet in this seem to be more than in the 
former, as is expressed in the next draught, 1.166. 
In this also the channels are smooth, and without streaks; whereas the cbannels 
of the English shell are as thick and deep streaked as the ridges. Again, the 
sides of these ridges in this shell are more at right angles, whereas in that they 
are flatter. 
This is the biggest scallop I have seen; it is also thick and heavy; it was of a blue 
clay-colour, but it was apparently old and weather beaten, so that the natural 
beauty of the living fish was perished. It is but shallow. It has but ten ridges, 
but the furrows betwixt them are very deep, and cut down almost at right 
angles: at the very head of the shell, betwixt the ears, the furrows are very deep, 
though small, and end ali in a point very elegant; whereas in the two former 
shells the heads are smooth, and the ridges and furrows in that part are almost 
obliterated. The ridges and furrows here are all of them curiously streaked. A 
good inch from the bottom of the shell, the ridges and furrows become suddenly 
of another fashion and grain, and are, as it were, transversely waved and smooth. 
I never saw but two of these, 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 to- 
wards the head a little crooked, whereas they lie all very straight, and run to a 
point. 
This is the only scallop of the kind that I have seen in Mr. C.’s collection. It is 
deep and hollow, thin and light; the ears exactly alike; it hath eighteen ridges, 
all which are of a dark heavy colour, almost black ; the furrows are all white, 
and both the ridges and furrows are smooth, and not at all striated; the ex- 
tremities of the ridges are notched very remarkably, not enough expressed in the 
figure. 
This is a white shell, (I never saw but one of them in Mr. Charltons collection,) 
shallow, with four large risings or ridges, besides other smaller: on the left hand, 
the ear had under it a row of small teeth, that were in a manner wholly defaced.
