Species i 6. (Mus. Cuming.) 

 Cardium maculosum. Card, testd oblongo-ovatd, ad urn- 

 bones subattenuatd, radiatim minute costatd, costis 

 octonis et quadraginta, angustis, confertis, postrt mis 

 subgraniferis ; pallide fulvd, rufescente punctulatd,

 The mottled Cockle. Shell oblong-ovate, somewhat 

 attenuated towards the umbones, radiately minutely 

 ribbed, ribs forty-eight in number, narrow, close-

 Cardium miiltistriatum, Sowerby, Pro. Zool. Soc, 

 1833. 

 Hub. St. Elena, West Columbia ; Cuming. 



The ribs of this species, though minute, are of too 

 decided a character to come under the denomination of 

 stria;. If it were not that I have the identical shell be- 

 fore me from which Mr. Sowerby described his Cardium 

 multistriatum, I should have hesitated to declare his 

 species synonymous with that under consideration. 



Species 77. (Mus. Cimiing. ) 

 Cardium oxygonum. Card, testd ongo-ovatd, umbones 

 versus attenuatd, radiatim costatd, costis quinis et 

 triginta, peculiariU r acutangulis, basi postice sub- 

 tiliter crenulatis, postremis muricatis, anticis sub- 

 tilissime en natis ; albidd, rosea profuse tinctd et 

 maculatd. 

 The sharp-angled Cockle. Shell oblong-ovate, atte- 

 nuated towards the umbones, radiately ribbed, ribs 

 five and thirty in number, peculiarly sharp angled, 

 finely crenulated at the base on the posterior side, 

 extreme posterior ribs prickly, anterior very finely 

 crenated; white, profusely stained and spotted 



with lose. 



Sowerby, Pro Zool. Soc, 1840. 



Hub. China, and the Philippine Islands; Cuming. 



This species exhibits a very peculiar plan of sculpture, 

 the ribs being sharply angled at the summit, and very 

 finely crenulated at the base, on the posterior side. 



Spe.ies 78. (Mus. Cuming.) 

 Cardium ^renicolum. Card, testd oblongo-ovatd, sub- 

 lique arcuatd, umbones versus attenuatd, radiatim 

 Janui 



costatd, costis senis et quadraginta, converts, Icc.vi- 

 bus, postremis squamulosis ; albidd, maculis rubidis 

 variegatd. 



The sand-inhabiting Cockle. Shell oblong-ovate, 

 somewhat obliquely curved, attenuated towards the 

 umbones, radiately ribbed, ribs forty-six in number, 

 convex, smooth, extreme posterior ribs squamu- 

 lous; whitish, variegated with large ruddy spots. 



Cardium maculosum, Sowerby (not of Wood), Conch. 

 Plus. 



Hob. Island of Ticao, Philippines (found among coral 

 sand at the depth of about six fathoms); Cuming. 



This is not the Cardium maculosum; it is of larger 

 size, longer in proportion, and has an oblique curve in 

 its growth. 



Species 7'.>. (Mus. Cuming.) 



Cardium sulcatum. Card, testd subelongato-ovatd, um- 

 bones versus attenuatd, ventricosissimd, radiatim 

 sulcata, in-ill posticd lirri, depressd ; ferrugineo- 

 ulhii. , /lii/cniiii/i flavo-olivaced indutd. 



The grooved Cockle. Shell elongately ovate, attenu- 

 ated towards the umbones, very ventricose, radiately 

 grooved, posterior area smooth, depressed ; rusty 

 white, covered with a yellowish olive epidermis.

 Cardium ftavum, Born. 

 Cardium serratum, Bruguiere. 



Hab. Mediterranean. 



The sculpture of this species is of such a very similar 

 character to that of the Cardium oblongum, that I at 

 first doubted whether they lie truly distinct. Upon 

 subsequent examination 1 find they differ constantly 

 in form, the Cardium sulcatum being more elongated 

 and so much more full and ventricose about the 

 umbones.
