now considered as distinct must be united with it. Cocconi (1873) 

 and Couffon (1902) believed T. avellana, Sow. (1823), not to be 

 separable as a good species. Then a prior and, I hope, a shorter 

 name will be found than pseudoasulcata, Sacco, for this species. 



Cossmann (1903, p. 157) mentions a Cyprcea {Bernaya) affinis, 

 Duj . ; it is surely only a slip, probably instead of globosa, Duj . 



Trivia arctica, Pulteney (1799). 

 This species was called by various writers arctica, Pult. (1799), or 

 arctica, pediculus and hullata, Montg. (1803), europcea, Montg. 

 (1808), or coccinella. Lam. (1810). Dautzenberg and Fischer (1912, 

 Res. camp, scient. Albert de Monaco, xxxvii, p. 168) wanted to 

 prove that arctica, Humphreys (1797), must be taken to designate 

 the species, but the eight words in his " Museum Calonnianum. ", 

 p. 7, can never be regarded as a name or description, being 

 non-binomial. The name monacha, Costa (1778, British Con- 

 chology, p. 33), also cannot be taken as valid.- not on account of 

 the designation '"' pediculus seu monacha ", but because its author 

 does not follow binominal nomenclature on pp. 12, 14, 120, 130, 

 133, and 238. Therefore arctica, Pult., must be retained as the 

 name of this common European Trivia.^ ? /*-' f^i^^W^u^. au, k f- 



Trivia atomaria, Dall (1902). 

 Hidalgo included this species as well as all other Trivia in the 

 genus Cyprcea. Though there is an older Cyprcea atomaria, described 

 by Gmelin in 1790, the name of Ball's species has to remain, for it is 

 described as Trivia, and belongs, without doubt, to this genus. 



Trivia lathyrus, Blainville (1826). 

 Formerly this species was well known under the name Trivia 

 pulex, Gray (1827, Zool. Journ., iii, p. 368 ; 1828, which, as Shaw 

 says, is incorrect). Shaw (1909, p. 311) pointed out that it was 

 described as Cyprcea lathyrus, Blainville, in 1826, and not for the 

 first time in 1830 ; but he omitted that it had been called Cyjorcea 

 sulcata var. D. (partim), and Cyprcea pulex (Solander MSS.) by 

 Dillwyn (1817, Descr. Cat., i, pp. 466, 467), which is preoccupied 

 by Cyprcea pulex, Bolten (1798, = ?). Trivia lathyrus, Blainv., 

 therefore remains. 



Trivia nivea, Sowerby (1832, 1837). 

 The name of this species, described as a Cyprcea, is preoccupied 

 by Cyprcea nivea, Bolten (1798, = ?), nivea. Dill. (1817, = Trivia 

 oryza, Lam.), nivea. Gray (1824, = Cyprcea eburnea, Barn., or 

 turdus. Lam., var.), nivea. Sow. (1825, = Trivia oryza. Lam.), 

 and nivea, Wood (1828, = C. lutea, Gron., var.). Therefore it must 



1 The author of this paper appears to have overlooked the note by 

 T. Iredale (Proc. Malac. Soc, XI, 1915, p. 333) on Trivia jonennis. Pennant. 

 Iredale clearly proves that the correct name for this species should be jonensis.
