KENNARD & WOODWARD : NOMENCLATORIAL NOTES. 79 



1805, February. Cuvier (Ann. Mus. Hist. Nat. Paris, v) described 

 and figured the animals sent him by Faure-Biguet and their anatomy, 

 under the name (p. 440, pi. xxix, f. 6-11) " La testacelle de France 

 {testacella haliotoidea [sic], Draj).) ". His figures leave no doubt 

 as to the species with which he was dealing. 



1805, June. Roissy (Hist. Nat. Moll. : Suites a BufEon redig. 

 Sonnini, v), in dealing with the genus Testacella, proposed (p. 252) 

 the name of T. eurojocea for the French form, cited Faure-Biguet's 

 paper, and remarked that that writer gave it as occurring in the 

 south of France, whilst Draparnaud recorded it from the north of 

 France. He ignored Draj)arnaud's name of haliotidea, and over- 

 looked Draparnaud's record of its occurrences both in northern 

 and southern France. Roissy's further species are T. cornina, 

 without stated locality, T. halioto'ides, from Tenerifie, and T. costata 

 from the Maldives. For the reasons already given Roissy's name 

 europcBa will stand in lieu of Draparnaud's haliotidea. 



1805. Late in 1805 Draparnaud (Hist. Moll. France, p. 121, 

 pi. viii, f. 43-48 ; ix, f. 12-14) repeated his name of Testacella haliotidea 

 unsupported by any references. We are sceptical concerning the 

 suggestion that the shells figured on pi. viii, f . 46-48, as of the adult 

 animal should be referred to T. maugei. 



1807. Ferussac (Essai method. Conchyl., p. 41) enumerated four 

 species : (1) Testacella haliotidea, Faure-Biguet (an error as to the 

 author of the species which was afterwards frequently copied) ; 

 Cuvier and Draparnaud are also cited, and Roissy's T. europcea 

 correctly placed as a synonym. (2) T. cornica [sic], Roissy. (3) 

 T. haliotoides, Roissy, Teneriffe. (4) T. costata, Roissy. In the 

 " Concordance systematique " (p. 116) only T. haliotidea appears. 



1810. Ledru's account of the expedition of 1796-8 (Voy. aux lies 

 de Teneriffe, La Trinite, etc.,tom. i, p. 187) by a printer's error gives 

 another spelling for the name of the Teneriffe species, viz. " Testacula 

 haliotoides ", Roissy's version being evidently intended. 



1819. Ferussac (Hist. Nat. Moll., ii, p. 94), following Montfort 

 (1810), changed the form of the generic name to the masculine and 

 cited Testacellus haliotideus, Faure-Biguet (pi. viii, f . 5-9, 11, 13-15), 

 with other references as before, and T. maugei, nobis (pi. viii, f. 10 

 and 12) with T. haliotoides, Lamk., as synonym. A repetition 

 of these occurs in his later Tabl. Syst. des Limaces, 1821, p. 26, with 

 the synonyms added to the former species of Testacella europcea, 

 Roissy, T. halioidea, Drap., and T. gallice, Oken. 



1822, April. Lamarck (Hist. Anim. s. Vert., vi, pt. 2) so far 

 underrated his original species as to say (p. 51) "II n'y a encore 

 quel'espece suivante qui soit bien connue '-, namely (p, 52) Testacella 

 haliotidea, which he attributes to Faure-Biguet, whilst citing 

 Draparnaud, Ferussac, and Cuvier. 



1831. Michaud, late in 1831 (Complement Hist. Nat. Moll. 

 France de Draparnaud, p. 9), furnished an example of careless
