I fear that Natica vitellus, Linne, is the true name of this species, but the confusion resulting from 

 the change may be an excuse for retaining Born's name. (See Hanley, Ipsa Linn. Conch., p. 394).

The authors quoted above may be pretty confidently taken as referring to this species. There 

 are other references which require mention, but which are unsatisfactory as certainly covering more 

 than this species, even if, as has been supposed, they really include it. These are Nerita; maroccana, 

 Chemnitz, Conch. Cab., vol. v. p. 270, pi. clxxxviii. figs. 1907-1910 [not figs. 1905, 1966, according 

 to PfeifTer, Kritisches Register zu Konch. Kab., p. viii., No. 6, who bases on these two figures his 

 West Mexican species Natica chemnitzii, which Dr Carpenter, Monog. Californian Shells, Proc. Zool. 

 Soc. Lond. 1856, p. 227, No. 106, considers distinct from his Natica 7 . maroccana, var. californica'] ; —
