54 ME. S. HANLET ON THE LINTSTEAN MS OF THE ' MUSEUM TJLBIC^.' 



SPONDYLUS. 

 This very natural genus was confused with Chama, and thus charac- 

 terized : — 



Testa imbricata. Cardo e callo gibbo oblique insert© fossula obliqua. 



S. G^DEROPUS. 5. imbricatus auritus, cardine dentato. 



"Rumph. t. 48. f. 1," "Gualt. t. 99. f. E. F. G," "Bonan. 2. f. 21," 

 ** Rondel, c. 40. p. 41," were the additional synonyms of the MS. The 

 " ad cardinem truncata " was an emendation for the previous " breviore " : 

 the " superiore " a misprint for the written *' inferiore " : the final remark 

 was not present. 



S. REGIUS. S. spinosus sulcatus inauritus, cardine dentato. 



No name was attached to this species : the previous one had been termed 

 Pectinitefi. 



S. PLiCATUS. Not mentioned in the manuscript. 



CHAMA. 



The members of this genus were included in Spondylus, except cordifor- 

 mis, which was referred to Bucardium. 



C. GiGAS. Sp. plicatus squamosus, ano hiante crenato. 



The species as originally defined was more comprehensive in its details 

 than when printed ; for the restricting " decussatim " had not been added, 

 and "Gualt. t. 93. f. B." was an additional synonym. The printed 

 additions were " obsoletis," "Margine reflexo," "exteriore duplicato lon- 

 giore," and the final remark. S. imbricatus was the intended name. 



C. Hippopus. Sp. plicatus muricatus, ano retuso clauso dentato. 



"Arg. t. 26. f. H." was an additional synonym of the MS. : the printed 

 20 should have been 10, as written : " ut in praecedente " was an emen- 

 dation : S. asper was the proposed name. 



C. Lazarus. Sp. imbricatus. 



Seba was not cited : " obliquam " followed " fossam " in the MS. 

 *' Elevatis," " longitudine testae," " productiore," " instar auris," formed 

 no portion of the early description. 



C. ANTiQUATA. Sp. subcordatus, sulcis perpendicularibus transversim 

 striatis. 



No name was attached to the original details, which appear to have been 

 altered ("in aliis minimum cordatum impressum fuscum "), and the 

 synonym of Bonanni added, in order to comprise that species {Cardita sul- 

 cata) which had been pictorially defined in the ' Systema.* " Gibba" was 

 preceded by " admodum " : " obsoletis " was not present. Cardita bicolor, 

 var. unicolor was probably intended. 



C. SEMiORBicuLATA. <S^. scmiorbiculatus comprcssus, dccussatc strl- 

 atus, rudis. 



" Interior " was the earlier reading of " primarius." 



C. coRDATA. Sp. cordatus, transversim striatus, hinc elongatus, com- 

 pressus.
