described by Dujardin nmst receive another name. I propose 

 parvodenticulata, Sacco (1894, p. 15), because this variety is common 

 in some parts of France whence Dujardin received his types. 

 I prefer it to hoernesiana, Sacco, which is named after a figure drawn 

 by Hoernes (1852) of a specimen from the Miocene basin of Vienna, 

 and which also {vide Sacco) is closely allied to Dujardin's type. 

 This latter name is not preoccupied. Cyprcea hornesi, Neugeboren 

 (1854, Zeitschr. Deutsch. Geol. Ges., v, p. 675), is a nomen nudum 

 proposed for a species never afterwards described under this name ; 

 Gisortia hornesi (not hoernesi), Lefevre (1878), is an Ovula and not 

 Cyprcea. 



Cyprcea glohosa, Sow. (1840), was changed to C. glohularis by 

 Edwards in 1854. 



Cypr^a listeri. Gray (1825). 

 Gray described two CyprcBa under this name. First, in 1824 

 (Zool. Journ., i, p. 384) a variety of C. felina, now considered a 

 species or, at least, a subspecies ( = melvilli, Hid.), then in 1825 

 (op. cit., i, p. 507) a species belonging to the group of G. erosa, Linn., 

 and identical with C. marginalis, (Sol. MSS.), as pointed out by 

 Dillwyn (1827, Zool. Journ., iii, p. 317). Cyprcea marginalis, (Sol. 

 MSS.) Dill., must therefore take the place of Gray's name. 



Cypr^a lynx, Linnaeus (1758). 

 Cyprcea vanelli, Linn. (1758, p. 720), is published one page before 

 C. lynx (p. 721). Lamarck (1810) believed at first the former to be 

 his C. turdus. Gray (1824) recognized its true synonymy, = lynx, 

 which is afterwards confirmed by Hanley (1855). Notwithstanding 

 the antedating by one page, the well-known name, C. lynx, Linn., 

 I think should be retained.^ 



Cypr^a madagascariensis, Gmelin (1790). 

 This name must not be changed to honoliduensis, as Melvill 

 (1888, p. 245) proposed, but must remain, in spite of the erroneous 

 locality implied, and hunoluluensis becomes a synonym. 



Cypr^a MARGARITA, Gray (1828). 

 Gray (1825, Zool. Journ., i, p. 516) described a species as C. 

 margarita, which he afterwards regarded (1828, op. cit., iv, p. 87) 

 as a young shell of C. cicercula. On the same page he then described 

 another species as C. rnargarita (as of Humphreys), believing 

 presumably that this name was now available. It is clear that the 

 name of the latter species, which has neither synonyms nor named 

 varieties, must be changed. I propose Cyjyrcea dillwyni, m. nov. nom. 

 This author had already described in 1817 a C. margarita which is 



^ This view is not in accordance with the International Rules on Zoological 

 Nomenclature, and if s3Tionymous C. vanelli should be substituted for C. lynx.
