The following species now belongs to the genus Cyprcea, subgenus 

 Cyprcedia ;— 



C. DACTYLOSA, Lam., var. georgii, Defr. (1826). 

 F. 574. — This variety must be considered as a synonym of C. 

 gervillii, Sow. (1820, Genera rec. foss. Shells, fig. 8), which is probably 

 a variety of Cyprcea {Cyprcedia) sulcosa, Lam. (1802). {C. dactylosa, 

 Lam., a synonym of sulcosa, is described in 1810 !) Gray's description 

 agrees very well with Sowerby's figure, which is also cited as repre- 

 senting georgii, while the name gervillii is put by mistake among 

 the synonyms of C. dactylosa, s. str.
