4-8. — C, suh'MUanumy peregrinum, impressum, Jaccardi, and Germani ; the first and last appear 

 to be referable to Lcevicardiumy the other three are Frotocardia, 



9-10. — C, Gillieroni and Valdense are based upon cast specimens which do not show any trace 

 of radiating striae or ribs ; their form^ however^ better agrees with Lcevicardium than with Serripes, 



11. — G, imhricatarium has the form of a Protocardium, but apparently no radiating strise on the 

 posterior declivity^ though this is distinctly separated from the rest of the shell by an interior 

 sulcus. 



12. — C, inornatum may belong to Serripes, but if no lateral teeth exist d''Orbigny^s sub- 

 sequent determination as Unicardium would appear to be correct. I will mention the species again 

 in the family LvciNiDyE. 



13. — G, sphceroideum is apparently a Lcevicardium, or like the next. 

 14. — G, Forhesij a Frotocardium, 

 15. — (7. Ihhetsoni is a Lcevicardium, 

 16. — G, Bellegardense, a Frotocardium, 



17. — G. Benstedi, The original specimens should be examined; Forbes does not give a char- 

 acteristic of the species, but merely alludes to its small size and longitudinal (radiating) ribbin^-. 

 From this the species would appear to be an Acanthocardium, 

 18. — G, Dupinianum is a Serripes, 



19-21. — G. Gonstantii^ Raulinianum, alpinum slyb species of Acantliocardiiim, 

 22-24. — G, Jiillanum, Marticense, Guerangeri belong to Frotocardium, 

 25. — G, Michelini may be a LcBvicardium, 



26-33. — G, prohoscideiim, Garolinum, Gentianum, incequicostaium, Fendinense, Genomanense, Jiyperi- 

 cum, canaliculatum are species of Acanthocardium, 



34-37. — G. Mailleanum, suh-ventricosum, Felagi, concentricum belong to Lcevicardium. 

 38. — G, Requienianum is to all appearance identical with Frotocardium Jiillanum, as stated by 

 Zittel, and others. 



39-41. — G. productum, intercostatum, hlspinosum are Acantliocardla, 

 42.— C. Gordierianum is a Frotocardium, 



43-47. — G, suh-guttiferum, Gorbierense, atacense, and perhaps also Toucasiamim and Faujasi are 

 Acanthocardia, 



48. — G, coniacum is a Gerastoderma. v 



49. — G. Bochehruni is based upon an insufficient cast. 

 50. — G, himarginatum is an Acanthocardium, 



51. — G Raulini may be a Lcevicardium, but the description is not satisfactory. 

 52. — G, insculptum ; the figure of this species looks more like that of a Linearia (Tellinid.e) 

 than of any of the CARDllN^. 



53. — G. radiatum seems to be a Gerastoderma, 



54-57.— C. Villeneuvianum, Itierianum, and apparently also G. pisolithicum 2ivA Futempleanum 

 are Acanthocardia, 



58. — G, corrugatum is a Frotocardium, 

 59-60. — G. Olisiponense and tiihuliferiim are Acanthocardia. 



61-62. — G. semipapillatum and lineolatum ; the first is insufilciently known_, the second may be 

 an Acanthocardium (see Favre Descript. Moll, foss., Lemberg, 1869, p. 113). 

 63-64. — G. alutaceum and pustulosum are Acanthocardia, 

 65. — G. Ottoi is a Gerastoderma. 



6(5. — (7. intermedium (? productum.) is an Acanthocardium, 

 67. — G. propinquum is a Gerastoderma,
