centre within. Mr. Gould spent much time in ohserving 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 rotundatdf 

 postice subrostratd paulo ringente, ad marginem siibexpansd, om- 

 nino (antice prcecipue) minutissime granulatd, pallide fulvd ; 

 costis 23 validis, rotundatis, quarum 8 postremis angustioribus, 

 postice subangulatis,Jimbriatis ; margine dorsali inflato ; 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. lUustr. f. 16. 45. Card, testa tenuis 

 rotundatd, postice subrostratd minutissime radiatim striata ; pal- 

 lide fulvd rubro radiatim fasciatd ; intus albd, fasciis binis ru' 

 bris radiatd ; striis postremis denticulatis ; epidermide 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. lUustr. f . 1 2. Card, testa oblique ovatdy 

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

 latd, purpureo ad latera fasciatd ; umbonibus Icevibus ; lateribus 

 marginibusque tenuissime sulcatis ; cicatrice ab apice 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. 



Cardium ringiculum. Conch. lUustr. f. 1 1 . Card, testa longitudi- 

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

 aspersd ; costis anterioribus angustis, inconspicuis ; tribus cen^ 

 tralibus latis, planulatis ad marginem valde dentatis ; decern 

 postremis angustioribus, paulo elevatis, ad marginem dentatis. 

 Var. testa pallide flavid a.
