SCHILDEE : ON CYFBMA AND TRIVIA. 117 



3rd ed. (1839), it is a nomen nudum. It is placed with nymphce, 

 Sow. (1870, Thes. Conch., Cyprcea, fig. 212). In Jay's Cat. of Shells, 

 dth ed. (1850), it is cited as a nomen nudum instead of carni- 

 color (!) , but the latter is a little more whitish-rose than fulvous. 

 Both names may be considered in future as synonyms of var, 

 fulva, Gray. 



C. PYRUM, Gmel., var. fossilis, Gray (1824). 

 C. 371.— Sacco (1894, Moll. terr. terz. Piem., xv, p. 25) cited 

 pyrum (Gmel.), Gray (Sacco quoted 1825), as a synonym of C. 

 porcellus, Broc. Lamarck's fossil C. rufa, which is identical with 

 Gray's var. fossilis as its author stated, therefore adding no further 

 description, was considered by Sacco (p. 26) as a synonym of 

 porcellus var. plioglohosa, Sac. Gray's variety without doubt 

 belongs to this species. I do not, however, recommend the use of 

 this name in place of plioglohosa, for their identity is not fully 

 established. 



C. ASELLUS, Linn., var. flavescens, Gray (1824). 

 C. 375.— This name must be given to Hidalgo's var. 1 of asellus 

 (1907, Mon. gen. Cyprcea, p. 274), but many specimens assigned to 

 this variety with reddish or yellowish bands are only decorticated, 

 I think. Two of the three figures cited by Gray, viz. the ones drawn 

 by Gualtieri, probably belong to C. felina, Gmel., or kirimdo, 

 Linn., but certainly not to asellus. 



C. niRUNDO, Linn., var. Formosa, Gray (1824). 



C. 377. — This varietal name must be considered as a synonym 

 of C. cylindrica, Born (1778). Lamarck described this shell as 

 hirundo var. (nameless), for he did not know the name given by 

 Born. Gray copied Lamarck's description (omitting the indication 

 of size) and called the variety formosa, though he knew Born's 

 species and described it some pages later as Gyproia cylindrica. 

 One must not wonder that Gray described the same species twice, 

 for he onl)'' saw two specimens of cylindrica, as he himself said — 

 one specimen a long time before he wrote his monograph, and 

 another, decorticated, at the time he was writing it. 



The name given by Gray does not touch the validity of Cyprcea 

 (now Trivia) formosa, Gask. (1835), for Gray's/ormosa was published 

 as a variety and never considered as a specific name. 



C. HIRUNDO, Linn., var. pulchella, Gray (1828).' 

 G. 78. — This is the shell afterwards called by Sowerby (1837, 

 Cat. rec. spec. Cyprcea, p. 6) Cyprcea hirundo var. oweni, which is 

 now considered a good species. But its name must remain C. oweni, 

 for pulchella is preoccupied by Swainson (1823) and Gray himself 

 (1824) for other species.
