Hub. Ticao, Philippinarum. H. Cuming legit. 



A beautiful pale-coloured specimen of this species has existed for 

 some time in the well-selected cabinet of Miss Saul, who, however, 

 possesses no information as to its locality. With this we have been 

 supplied by Mr. Cuming, who collected some richly coloured indi- 

 viduals from the above-mentioned island : they were found in coral 

 sand, on reefs, at low water. 



Cardium attenuatum. Card, testa Ifsvi, cuneiformi, compressd, 

 oblique elongatd, postice subcomplanatd, omninb obscure striata, 

 ad marginem deritatd ;Jlavd, rubro maculatd, maculis posteriori- 

 bus validis ; inlus alba. 

 Long. 1-80; lat. 1-20; alt, 2 60 poll. 

 Hab. ad insulam Ceylon. 



A good figure of this species is found in Wood's ' General Coii- 

 chology,' accompanied by the following erroneous statements : firs;, 

 that it is C. biradiatum of Brug. ; and second, that C biradiatnm of 

 Brug. is only a variety of the British species (C serratum), which is 

 improperly named C. leevigatum by him and some other authors. 

 From the apex to the ventral margin, it measures longer in propor- 

 tion than any other species. 



Cardium Elenensk, Conch. Illustr. f. 58. Card, testa tenui, Icevi, 

 ovali, postice subacuviinatd pallide fulid, fusco et purpurea mi- 

 nute maculatd, intus fused rubro fasciatd ; umbonibus inconspi- 

 cuis, purpurea maculatis. 



Long. 0-75; lat. 0"50 ; alt. 0-75 poll. 



Hab. ad Sanctam Elenam. H. Cuming legit. 



Very nearly resembling C. Brasilianum, but not coloured in radi- 

 ating lines, as in that species, and not so much elongated at the 

 posterior ventral margin. Found in sandy mud, at seven fathoms. 



Cardium lyratum. Conch. Illustr. f. 40. Card, testd ventricosd, 

 rotundatd, subceqidlaterali, pallide fulvd, epidermide rubra-pur- 

 pured indutd, intus aured ; antice decussatim plicatd ; cosiis 

 numerosis ; anticis tenuissimis ; mediis validioribus ; pasteriori- 

 bus distantibus, angulatis. 



Long. 1-70; lat. 1-40; alt. 1-70 poll. 



Hab. Dumaguete, ins. Negroes, Philippinarum. 



The C ^olicum of Born (C. pectinatum, Linn., according to Brug.) 

 has a space on the posterior side of the shell entirely free from ribs 

 in either direction. Bruguiere describes it as characterised by "trois 

 faces distinctes," of which the first {the posterior) is " lisse, sans cotes 

 ni stries," and the figures in Chemnitz represent the same peculia- 

 ritv. In the shell before us, the whole of the posterior side is covered 

 with radiating ribs, no space being left smooth. In other respects 

 it exactly resembles the " Janus " celebrated by ancient naturalists, 

 and it is now almost as frequently met with in cabinets. The dif- 

 ference between the two species has been long observed, although 

 they have not hitherto been separately described. Mr. Cuming has
