REPORT ON THE GASTEROPODA. 507 



mouth uue coquille qui ressemble pari'aitement a ces derniers, et qui doit etre son analogue vivant. 

 Elle m'a ete envoye"e sous le nom de Turbo politus ; on trouve aussi cet espece fossile a Dax." 



Without discussing the Angers fossil, we find here at least two other and quite distinct species 

 mixed up with Eulima distorta, Defr., viz., Eulima polita (?), Linne, as represented by living speci- 

 mens from Weymouth, and a Miocene fossil from Dax, near Bordeaux. It is this latter species which 

 is called Eulima distorta by Basterot (Coq. foss. Bord., p. 36), and by Grateloup (Coq. foss. Adour, 

 vol. i.), but was afterwards distinguished as Eulima similis by d'Orbigny (Cour. de Pal., 1847). 

 Searles Wood (loc. cit. supra) with a query identifies this Miocene fossil from Bordeaux with the 

 living species, but Deshayes (Anim. s. vert. Paris, vol. ii. p. 543) says that the fossil is a much larger 

 form, and quite distinct, 



Philippi (loc, cit. supra) attributes the name " distorta" under which he quotes it, to Deshayes 

 (Coq. foss. Paris, vol. ii. p. Ill, sp. 10, pi. xiii. figs. 24, 25) instead of to Defrance, and applies it to 

 the living species from the Mediterranean, as indeed Deshayes too originally did (Coq. foss. Par., &c, 

 and also in his edition of Lamarck, Anim. s. vert., vol. viii. p. 454), an opinion which the latter, 

 however, subsequently corrected (Anim. s. vert. Par., &c.) 



Dr Gwyn Jeffreys (Brit. Conch., vol. iv. p. 190) says that Enlimas are not parasitic. Strictly 

 speaking, that is true, for they do not prey on the living tissues of the animals they inhabit, but 

 they seem largely to live on the excrement of other animals. In Madeira I found them constantly, 

 and sometimes as many as four or five together, among the spines near the vent of Echinus 

 esculentus, Gmelin.
