Note. The under or lefler Shell of any Pedlen is eafily to be known from the upper becaufe 
the imprefiion or the place where the nervous Ligament did adhere is ever to the left Side of thc 
under Shell, and to the right Side of the upper or bigger Shell i and this to be underftood in 
like manner of all Bivalves.

197. 32. It is but on the one Side or upon the Back of the greater Shell that the Hooks are, fo that the 
other half or lefTer Shell is without thcm : and thercfore we feldom have a Twig of them but thc 
lefTer Shells are all wanting. Alfo the lelTer valve is edged near the Hingc with fmall Notches. 
The Figure of this Kind of Tree Oifter is very odd and of wonderful Variety j fome long and 
narrow, fome round and broad &c.

in the Province of Nicaragua on the fouth Sea, are many Shell-Fifties of <2 longForm\ fome a 
Cubit long, fome lefs, creafed, growing broader and broader to the End ; when they are opened 
they have a fiftiy Subftance within thcm and ftiine within as Pearl Oifters do, half their lengrh, 
thence by degrees lofing that ftiining towards the broadcrEnd. The Pearls within them are 
not fo fine as the other. The Indians ufc the Shells to dig their loofe Ground, faftning ihe Shell 
to a Handle of Wood, binding it faft and making a Kind of a Spade thereof. G. F. dc Oviedo.

N.B. This is the lefl^er or under Shell of this Sort of Spondyle, the upper SheU having a 
Break, and from that Break to the Hinge a Slope Cut very remarkable, as though done by 
Arc noc Nature.

210. 44. This Shell hath high Ridges and ftiarp, in fome more and fome lefs ; I have counted nine or 
ten in fome. By the toothing of the Hinge it is a Spondylus, to which the Strengch and Thick-

Sir Ric. Hawkins apud Purchas. L. 7. C. 5. Part. ^th. I faw a very fmall Pair of Shells from 
Jamaica, which were long, Oifter like, but the Colour of the Infide was of a blueifli Mother 
of Pearl Colour, and the Hollow or Bafon of a Rhomboid Figure ; the Skirts encompalfed 
with a Ridge of the Shell, reaching much beyond it, as in the firft Figure of the Mother of Pearl 
Kind (N°. 224. 58.) is repreiented. One of the Shells was much fliallower than the other, thc 
Neck was drawn out to a fharp Point after the Manner of Pinnas or Mufcles ; and the Connexion 
of the Shell feemed to be by a certain Number of Ties, which makcs me put it in this Divifion. 
268. 104. I have feen one of thefe Shells, thrice as big as this, but they arc rare. 
This Shell is very ftrong and ponderous, there are two remarkable broad Lifts from the 
Top to the Border of a dark hair Colour ; the tranfverfe Creafes are unequal and not thick fet. 
N.B. I have feen fome of thefe (or be it a different Species, which I incline to) which werc 
of a brownifti chefnut Colour, very littlc fafciated, but rather fmooih ; and whereas the 
Neck and Head or Point of this Shefl is very deeply fafciated, thefe wtre very fmooth ; but 
in all Things elfe thcfe were very like. 
271. 107. This is a very fliallow and exceeding thick and ponderous Shell, fmoothon the outfide, or if 
you will, fafciated or irregularly worked. On the Infide towards the lefc Hand ic is of a violec 
Purple : The Edges is very full of fmall and ftiallow Hatchings, buc noc indenced, che ex- 
treme Edge being fmooth. This is the only Shell of the Kind that I have feen ; it was in 
Mr. C.'s CoIIedlion chac I faw ic, and caufed ic to be figured. 
N.B. I have feen two other Species very near refembling this Shell in all Things : The 
firft differs in that is very finely ftriated on the Outfide betwixt the regular Wrinkies only, 
thofe Strias being of a very peculiar Make, and this feems to bc a Rock-ftone in the Figure 
of a Shell, being cxtrcmely white or chalky, and friable. The fecond is not near (o thick 
and ponderous as the other two defcribed, and is whice boch withinfidc and withouc, buc is 
fafciaced wich fine thin rifing Edges at certain Diftances, there being properly no Furrows ac 
all anfwering the Edges ; and was brought from the Bay of Campeche in the weft Indies.
