An extensive series of new species of the genus Cardium was ex- 

 hibited by Mr. Cuming, and the following account by Mr. G. B. 

 Sowerby, Jun., of their characters, was read. 



Cardium Sinense, Conch. lUustr. f. 35. Card, testa rotundatd, 

 poslice subrostrald paulo ringente, ad marginem subexpansd, om- 

 nino (antice jtrcecipue) minntissime granulatd, pallide fulod ; 

 costis 23 validis, rolundatis, qiiarum 8 postremis angustioribus, 

 postice subangulatis,Jimbriatis ; margine dor salt hiflato ; ventrali 

 interne fortissime dentalo. 



Long. 1-55; lat. 1; alt. 1-40 poll. 



Hab. ad mare Sinense, et ad insulas Philippinas, invenit H. Cuming. 



Slightly resembling C. Asiaticum, from which it is distinguished 

 by having larger and fewer ribs, and a small fringe on the posterior 

 ribs. Found in sandy mud. 



Cardium striatulum, Conch. Illustr. f. 16. 45. Card, testd tenui, 

 rotundatd, p>ostice subrostrald minutissime radiatim striata ; pal' 

 lide fulvd rubra radiatim fasciatd ; intus albd, fasciis binis ru- 

 bris radiatd ; striis postremis denticulatis ; epidermiJe fused. 

 Long. 1- ; lat. 0-60; alt. 0*90 poll. 



Hab. ad Australiam et ad Novam Zelandiam. G. Bennett legit. 

 The pink-striped bands which give so much brilliancy to this shell 

 when in a young state, are scarcely to be traced in the older speci- 

 mens. The doubt as to their identity, which this circumstance at 

 first created, was only removed by the most careful comparison. 



Cardium Australe, Conch. Illustr. f. 12. Card, testd oblique ovatd, 

 tenui, albd, purpureo-rubro fuscoque prcecipue ad umbones macu- 

 latd, purpureo ad latera fasciatd ; umbonibus Icevibus ; lateribns 

 marginibusque tenuissime sulcatis ; cicatrice ab ajnce ad margi- 

 nem posticum decurrente. 

 Long. 1-20; lat. 0-85; alt. 1-30 poll. 

 Hab. ad Australiam, et ad mare Sinense. 



This species differs from C. tenuicostatum and C. papyraceum, in 

 its proportions, being longest from the apex to the ventral margin ; 

 and also from the latter in the narrowness of the posterior ribs, and 

 in having a distinct groove on the posterior side. Since the appli- 

 cation of the above name, specimens have been met with in Mr. 

 Cuming's Collection, named C sauciatum by Dr. Beck, who, how- 

 ever, to the best of our knowledge, has not published it.
