This Shell is well figured, it is fiat and fhallow for the Bignefs, of a yellowifii pale Colcur. 
The lifts are fmall and very regular, and not much extant but fiat, fo it is, as it wcre, fmooth. 
Here alfo is a fmall lunar Sinus near the Nib. Ab Infula Jamaica. 
This Shell is white infide, outfide : probably brown when the Animal is in it, and that it is 
frefii. The Lifts are are fo very fmall and many, that the Defign hath fcarce figured the one 
half of them. It hath a reraarkable lunar Sinus on the one Side of the Nib j it is a thiclc 
and ftrong Shell. This is found on the Englifli Coaft. 
This Shell is very thick and fliallow, the Edges fmooth, the circular Wrinkles are very 
numerous, fmall, and not very rifing it is ftaincd with a brown hair Colour, and in forne 
Places with that Colour indented or waved. The Figure of the Head or Point is very odd 
and flattilb. It is a rare Cockle j I never faw but two Pair of them. 
This Shell was taken up on the Coaft of Norway. The Lifts are fine and fmall and pretty 
regular, but ftiarp and rough, it is moderately ftrong for the Bignefs and not very ftiallowV 
It is white Infide, Outfide. The lunar Sinus near the Nib is not to be obferved in this 
Shell. 
Ab India Occidentali. 
This Shell is thin comparatively to thofe like it in this and the other Tribes of PeBunculL 
It is prettiiy veined with a purplifli Colour, in others brown, it is fafciated, but neither re- 
gularly nor very high and confpicuous ; the Ridges of the Shell are fmooth and not indented, 
which does fufficiently diftinguifh it from the other in this Tribe. Ind. Occident. 
Ab India Occidentali. 
This is a very thick and ftrong Shell and ftiallow, it is irregularly fafciated, there are of 
them alfo forne lefs, of a different Species, that are in forne Parts irregularly ftriated alfo : 
It is marbled with a yellowiffi brown Colour, in forne prettiiy veined a little purplifb j the 
Edges on their Infide are quite round about to the very Hinges finely indented or rather 
hatched. 
Concha echinata GefnerL 
Ab Africano Litore ad Fluvium Cong(L 
Concha ftriata longa Rondeletii. 
The fmall ones of this Kind are very beautiful, yellowiffi, with dark brown Spots running 
in an undulated Manner from Side to Side. 
There are Shells alfo of this Kind very much bigger than that which is reprefented. Yet 
all are rare. 
Concha imbricata minima Aldrovandi. 
Tridachnes Aldrovandi. 
Inter Concharum genera omnia, quse nobis videre contigit hucufque, & alii recentiores 
defcripferunt, nullam confpeximus majorem hac a nobis nunc depida : quare Maxime cog- 
nomen meruit, & ob teftas craffitiem, gravitatem atque duritiem. Marmoream denominavi- 
mus. Illuftri nota ab aliis fecernitur, quia Septenis tantum a Cervice ad Os dudis diftinguitur 
magnis ftriis, totidemque ftrigibus inter fe magnitudine paribus, alternatim ad invicem op- 
poficis, cum occluditur tefta. Figura Concha; oblonga, per obliquum Cervicis, ab uno latere 
longiore. Clavicula magna cervici adeft elata, atque altera exigua admodum circa extremum 
Conchae, parte breviore, canaliculis illis fubjacentibus, quibus alterius Concha, vel Teftae 
pars claviculje refpondentes conneduntur. Contraria vero majoris Claviculse parte feptem 
confpiciuntur incifurre Scalarum ritu decrefcentes, qu« pars circa cervicem fe dilatans recli- 
nat; atque auris modo qu$ pedini eft, non exerta, fed infra Conchs craffitudinem produ- 
citur. Linea locus, quem Animal occupat Conchae internus, ac magis pallens definiri videtur ; 
colore deinceps per ambitum circa ora candicante. Marmoris politi modo, fplendido. Externa 
Conchae parte Striarum additamentis craffis tota exafpera redditur, quibus tegularum et im- 
bricum modo, alia fuper aliis fuperaddita videntur; quapropter imbricata dici merito potefto 
Striges vero lineis tantum exafperantur denfioribus, finuofis, oblique decurrentibus ab altero 
ad alterum Conchs extremum ; magnitudine et finubus imparibus juxta ftriarum & ftrigium 
magnitudinem atque craffitiem; at circa ora quidem finu et circulo pollicari amplitudine 
undofae confpiciuntur, circa cervicem vero minimas admodum. Ab ea parte, duas uncias 
crafitie fuperat Concha, circa ora in tenuitatem abit. 
The Mufcle in the firft Place is large for the Kind, the Strias are big, rifing, and a little 
undulated, and towards the broad End of the Shell are double or branched. This ispurpliffi, 
at leaft in Places on the Outfide, the reft white and mother of pearl Colour. 
This Mufcle is fmooth and forne of them are twice as big as it is figured ; the Colour of the 
Outfide in forne is reddifli, and white within, but thefe I judge are decayed, and thefe are 
moftly pretty ftrong and thick : but thole of a Frelhnefs are on the Outfide of a brown hair 
Colour, and of a purplilh red within. Thefe come from Jamaica.
