ON SOME GENERIC NAMES FIRST MENTIONED IN THE 

 "CONCHOLOGICAL ILLUSTRATIONS."

In reviewing the Fissurellidae of the Pacific coast of North America 

 I found some confusion existing in the synonymy of several well- 

 known species and genera, the clearing up of which may have some 

 interest for students. 



The following data will serve toward that end: 



Genus LUCAPINA (Gray) Sowerby, 183B. 



Lucapina (elegans) Gray, in Sowerby, Conch. 111., Fissurella, p. 4, No. 38, fig. 29, 

 June, 1835; as synonym of F. cancellata Sowerby, Conch. 111., p. 4 (as of Solander MS.) 



Lucapina Philippi, Test. Utr. Sicil., vol. 2, 1844, p. 90, cites cancellata Sowerby, as 

 type and sole species mentioned. 



Lucapina (Gray) Herrmannsen, Index Gen. Mai., vol. 1, p. 627, 1846; cites Fis- 

 surella cancellata as type. 



Lucapina Gray, Syn. Cont. Brit. Mus., ed. 42, p. 147; nude name under Fissurellidae, 

 no species cited; ed. 44, 1840, p. 114 (ed. 44 A., 1840, p. 117), one line of diagnosis, 

 no species cited. 



Lucapina Gray, Proc. Zool. Soc, 1847, p. 147, No. 160, cites Fissurella aperta Sowerby, 

 and L. elegans Gray. 



Lucapina (Gray) Herrmannsen, Index Gen. Mai., Suppl., p. 76, 1852, cites Fissurella 

 aperta Sowerby, following Gray in Proc. Zool. Soc, 1847. 



Lucapina Gray, in M. E. Gray, Fig. Moll. An., vol. 4, p. 92, 1850, cites L. cancellata 

 and L. crenulata, nude names, as examples. 



Foraminella (Guilding MS.) Sowerby, Conch. 111., p. 4, No. 38, June, 1835, as Forami- 

 nella sowerbii Guilding, MS.; St. Vincent, West Indies. This name precedes 

 Lucapina in the text, and is cited as a synonym of Fissurella cancellata Sowerby, 

 Conch. 111., p. 4, 



Foraminella Guilding, Cat. Conch. Nom., 1845, according to Agassiz in Scudder, 

 Nomencl. Zoologicus, p. 139, 1882. — Catlow, Conch. Nomencl., p. 102, No. 11, 

 1845; cites from Sowerby, Conch. 111., 1835. Not Foraminella Leven. Brach. 1902.) 



Lucapina H. and A. Adams, Gen. Rec. Moll., vol. 1, p. 447, 1854; examples figured 

 L. reticulata Donovan and L. crenulata Sowerby; vol. 2, p. 630, 1858, notes segrega- 

 tion of subgenus Glyphis Carpenter, and cites G. inaequalis as sole example, also 

 Capiluna Gray, as synonym. 



Lucapina Woodward, Manual, p. 150, 1852, F. elegans Gray, sole example cited; but 

 it is confused with F. crenulata Sowerby, from which the diagnosis is drawn. 



Glyphis Carpenter, Mazatlan Cat., p. 220, 1856; first species Fissurella inaequalis 

 Sowerby. (Not Glyphis Agassiz, 1853.) 



Proceedings U. S. National Museum, Vol. 48— No. 2079.
