This is the upper shell with teeth, and belongs to the scallop described 186. 24. 
above, where it is to be inserted. 
This shell is freqnently to be met with on the Irish seas, and on the Welch coast. 
I never saw any of them mucli bigger than that which is figured: it is thin, 
light, and shallow; the ears mueh of a bigness; it is of a reddish brick colour, 
spotted or marbled with dark brown and whitish spots; the ridges are above 
twenty, finely striated, as well as the furrows betwixt. In the inside of the shell, 
the furrows or hollows answering to the ridges on the outside are very shallow 
and faint. N. B. This is the upper or bigger shell which I have now described, 
having never seen a pair. This I have found to be added to our English Stores 
since the publishing of my History of the Animals of England. This is the tooth- 
less shell, and the ears more alike. There is also the figure of the upper or bigger 
shell, with teeth next under the ear, and the ear a little hollowed away. (See 
190 . 27 .) 
This shell is small, variously coloured; as red like coral, yellow, marbled, &c.: the 
ridges are about twenty, very distinet, and rising, but are hatched across: the 
furrows are deep and striated: the two ears are much of a bigness: and the shell 
is thin, and moderately hollow or capacious: the furrows in the inside answering 
to the ridges on the outside are deep, and the sides at right angles. There are 
many of these sliells in the cabinets of the curious. This was the bigger or upper 
shell which is figured, not having seen a pair. Note. The under or lesser shell 
of any Pecten is easily to be known from the upper; because the impression, or 
the place where the nervous ligament did adhere, is ever to the left side of the 
under shell, and to the right side of the upper or bigger shell: and this to be un- 
derstood in like manner of all bivalves.

It is but on the one side, or upon the back, of the greater shell that the hooks are, 
so that the other half, or lesser shell, is without them ; and therefore we seldom 
have a twig of them but the lesser shells are all wanting. Also the lesser valve 
is edged near the hinge with small notches. The figure of this kind of Tree 
Oyster is very odd, and of wonderful variety; some long and narrow, some round 
and broad, &c. 
Ostrea, alicujus Virginum ce valva altera minor. In the gulph of Orotigna and the 
islands therein, in the province of Nicaragua on the South-sea, are many shell- 
fishes of a longfarm; some a cubit long, some less, creased, growing broader and 
broader to the end: when they are opened they have a fishy substance within 
them, and shine within as pearl oysters do, half their lengtb, thence by degrees 
losing that shining towards the broader end. The pearls within them are not so 
fine as the other. The Indians use the shells to dig their loose ground ; fasten- 
ing the shell to a handle of wood, binding it fast, and making a kind of a spade 
thereof. G. F. de Oviedo. Purchas. 1. 5. c. 3. part 3. 
Concha corallina aspera Aldrovandi. N. B. This is the lesser or under shell of this 
sort of Spondyle; the upper shell having a break, and from that break to the 
hinge a slope cut very remarkable, as though done by art, not nature.

This shell hath high ridges and sharp, in some more and some less; I have counted 
nine or ten in some. By the toothing of the hinge it is a Spondylus, to which 
the strength and thickness of the shell answers: it is of a pale reddish colour. An
