[The genus Capolina, as erected by d'Orbigny in I850, contained 10 nominal species none of whIch is mcluded.In the genus by modern authors, and it would be a senior synonym of Toucosia MUNIER-CHALMAS, 1873, by strict application of the International Code. It would only be retained in the sense in which it has come to be used.by attributing it to D'ORBIGNY, 1850, and by declaring C. striata to be its type species, setting aside any prior .deslgnatlons.
