been used by Simroth (1910, Deutcbe Siidp. Exped., xii, part iii, 

 p. 158) for another genus of mollusca. 



Corrections made by an author to the name given by himself 

 should only be accepted if they were published, at the same time aa 

 the wrongly written name, as " errata ", but not afterwards. 

 Panther inaria, Sacco (1894, p. 67), has to stand, not Panterinaria 

 (op. cit., p. 10), also childreni, Gray (1825, Zool. Journ., i, p. 603), 

 not childrini (op. cit., p. 518), etc. ; and Lamarck had no right to 

 change in 1822 his own Trivia ovulata (1810) into T. ovula (cf. Shaw, 

 1909; p. 312). 



CyprtEA gangeanosa (Solander MSS.), Dillwyn (1817). 



Most authors wrote gangrenosa, Roberts (1885, in the index, 

 p. 215), and Shaw (1909) gangrcenosa ; but Dillwyn (1817, Descr. 

 Cat., pp. 462 and 465) wrote gangranosa three times, which spelling 

 must be retained. 



I may here. add that the following names must be written Cyprcea 

 saulce., Gask. (1843), sophia (Bernay), Desh. (1866) (not to be con- 

 founded with sopJdce, Braz., 1876 = ovum, Gmel.), Trivia maugeri, 

 Gray (1832), and the subgenus Bernaya, Jouss. (1884), and not 

 saulice, saulii, sophia^, maugerice, maugerce, and Bernayia, auctt. 



Cypr^a gemmula, Weinkaufi (1881).^ 

 Gould (1845, Proc. Boston Soc. Nat. Hist., ii, p. 27) described a 

 Cyprcea gemmula, which is a synonym of Trivia exigua. Gray. 

 Weinkauif (1881, p. 163) was aware of this ; nevertheless, he gave 

 the same name to another species closely allied to the West American 

 C arahicula (1881, p. 54). There are no synonyms or varietal names ; 

 therefore I propose Cyprcea massauensis, m., nov. nom., for the 

 species inhabiting the Red Sea and western part of the Indian 

 Ocean. 



Cypr^a gibbosa, Borson (1820). 

 Cossmann (1903, p. 154) substituted the name polysarca, nov. nom., 

 for this species, believing gihbosa to be preoccupied by Linnaeus. 

 But gihhosa, Linn. (1758), is described by Linnaeus, Gmelin, and 

 Dillwyn as a Bulla, by Lamarck as an Ovula, and never as Cyprcea 

 (now it is considered as Cyphoma). Cyprcea gihhosa (Schrdter), 

 Schmidt (1818, Versuch beste Einrichtung Conch. Samml., p. 220), 

 which was not known to Cossmann, is only a nomen nudum, and 

 also does not touch the validity of the name given by Borson, which 

 must be used for the species belonging to the subgenus MandoUna. 

 Cossmann, at all events, had no right to give a new name, for at 

 least two of the varietal names given by Sacco (1894, mucronatoides 

 and pergihha) could have been used for designating the species. 



Cypr^a globosa, Dujardin (1837). 

 Cyprcea glohosa, Sow., now considered a Trivia, was described 

 in 1832 (Conch. Illustr., fig. 34) ; therefore the fossil species
