CARDIUM, 



Species S. (Mus. Cuming.) 



Cardium bullatum. Card, testa transverse ovatd, tenui, 

 utrinqite Mante, latere postico producto ; costatd, costis 

 ad sex septemve et quadraginta, suba?igustis, stria sub- 

 tilissimd elevatd interveniente, costis anticis erenulatis, 

 posticis squamiferis ; albidd, roseo purpureove sparsim

The studded Cockle. Shell transversely ovate, thin,

Variety 0. 



Testa latere postico minus proilucto, east is sidiphniiuribiis,

Cardium aspersum, Sowerby, Pro. Zool. Soc, 1833. 



Hub. St. Elena and Monte Christi, West Columbia (found 



in sandy mud at the depth of seven fathoms) ; Cuming. 



I do not conceive that the modification of character 



which distinguishes variety 0, figured in the ' Encyclopedie 



Methodique,' can be regarded of any particular specific 



importance. 



Species 9. (Mus. Cuming.) 



Cardium papyraceum. Card, testa depresso-cordata, 

 tenia, fragili antice minutissime gratmlatd, radiatim 

 impresso-striatd, striis rudo-hicisis, epidermide radi- 

 cantibus ; albidd aid jtamcante, purpurea hie illicpalli- 

 dissime linctd, umionibu* rufo-purpurek, intus rufo- 

 purpured. 



The papyraceous Cockle. Shell depressly heart- 

 shaped, thin, fragile, anteriorly very minutely granu- 

 lated, radiately impressly striated, stria- rudely en- 

 graved, driving root to an epidermis; whitish or yel- 



lowish, faintly tinged here and there with purple, um- 

 bones reddish purple, interior reddish purple.

Sowerby, Conch. Ulus. f. 56 (not f. 55). 



Hah. East end of the Island of Luzon, Philippines (found 

 in sandy mud at the depth of seven fathoms); Cuming. 



The accompanying figure, and Fig. 56. of Mr. Sowerby's 

 ' Conchological Illustrations,' represent varieties of the true 



ViinVuiiii papi/rare/iHt, and are quite distint from a fine new 

 species which has been confounded with it in the same 

 work, at Fig. 55. This shell, for which see Cardium mu- 

 ticum, Plate VI., is of much larger dimensions, of a more 

 transversely ovate form, and exhibits no indication of that 

 curious minute granulation which characterizes the post* - 

 rior side of the Cardium papyraceum, after the manner of 

 the Cardium Sinenst . 



Species 10. (Mus. Cuming.) 



Cardium multispixosum. Card, testa rotundatd, reiilri- 

 cosd, radiatim costatd, costis ad tribus et tricenis, utrin- 

 que acute angulatis, breoUspinosis ; incarnato-albd, ro- 

 saceo hie ttlic pallide tinctd, interstttiis inter costas 

 nonnunquam fuscescentibus, spinis aliis ,- intus albicante, 

 radiatim symmetric^ sulcata. 



The many-spined Cockle. Shell rounded, ventricose, 

 radiately ribbed, ribs about three and thirty in num- 

 ber, sharply angled on both sides, armed with short 

 spines; flesh-tinted white, palelj stained here and 

 there with pink, interstices between the ribs some- 

 times brown, spines white; interior white, radiately 

 symmetrically grooved. 



Variety (i. 



Testa grandior, ens/is lationbus, de quatuor et vicenis a dno- 



detricenis. 

 Shell larger, ribs wider, from four and twenty to eight 



and twenty in number. 

 11,,/,. Islands of Mindanao and Zebu, Philippines (found 



in sandy mud at low water, and at the depth of from 



six to twenty-five fathoms); Cuming. 



The ribs of this beautiful species arc peculiar in being 



quite under-grooved, as it wen', on each side.
