centre within. Mr. Gould spent much time in observing the habits 

 of those birds, and was fully satisfied that the " runs " were actually 

 formed by them, and constructed for the purposes described. 



Sept. 8. — James Whishaw, Esq., in the Chair. 

 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, 

 postice suhrostratd paulo ringente, ad marginem subexpansd, om- 

 ninb (anlice jvescipiie) 7niniitissimc granulatd, palUde fulvd ; 

 costts 23 validis, rolundatis, quarum 8 postrem'is angustior'ihus, 

 postice suhangulat\s,jimbriatis ; margine dorsali hi/lato ; ventrali 

 interne fortissime dentato. 



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, postice suhrostratd minutissime radiatim striatd ; pal- 

 • tide fulvd rubro radiatim fasciatd ; intus alhd, fasciis binis ru- 

 hris radiatd ; striis j)ostremis denticulalis ; epidcrmide 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. 1 2. Card, testd oblique ovatd, 

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

 latd, purpurea ad latera fasciatd ; umbonibus Icevibus ; laleribus 

 marginibusque temussime sulcatis ; cicatrice ab ajjice 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 ha^dng 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. 



Cardium ringiculum. Conch. Illustr. f. 11. Card, testd longitudi- 

 naliter ovali, tenui, utrinque hiante ; postice elongatd, sub- 

 aspersd ; costis anterioribus angustis, inconsjncuis ; tribus cen- 

 tralibus latis, planulatis ad marginem valde dentatis ; decern 

 postremis angustioribus, paulb elevatis, ad marginem dentatis. 

 Var. testa pal tide ffavidd.
