NO. 17 LAMARCK S GENERA OF SHELLS KENNARD ET AL, I9 



Genus Type & Synonym 



Bull era B. apcrta {Bulla aperta. Linn.) 



§Sole species. Genotype Lk. Syst. 63 is B. 

 plane iaiia, n., which it is admitted includes the 

 Bulla apcrta, Lin. The latter therefore stands. 

 [Generic name preceded by Philine, Ascanius, 

 1772, monotype P. quadnpartita, Asc.= 

 aperta, Lin.] 



231 95 Bulla 



232 96 B. lignaria (Idem. Linn.) 



§Lk. Prod. 75, Lk. Syst. 90, Mtf. ii, 331 and 

 Fl. 1818, 310 all name B. ampulla, Lin., as 

 type and this must stand since Montfort, 1810 

 ('i» 335) took lignaria as genotype for his 

 Seaphander. 



233 97 Laplysia L. dc pilaus (Idem. Linn.) 



§Same in Lk. Syst. 62. 

 ' [Generic name altered by Cuvier 1798 (Tabl. 

 386) to Aplysia with dcpilans as genotype. 

 He is followed by Fleming, 1822, 576. Pils- 

 bry's advocacy of the exchange of the generic 

 names Aplysia and Tethys is to be deplored.] 



233 97 Dolabella D. Ruiupliii 



§Lk. Syst. 62 has genotype D. eallosa, n., which 

 in the Hist, is wrongly included in the later 

 date D. Ruiuphii, Cuv. 



234 98 Ouch id iu in [No shell.] 



§|Lk. Syst. 65 cites O. typluc, which is Bu- 

 chanan's genotype.] 



234 98 Parnuieclla P. caliculata 



§ Genotype P. Olivieri, Cuv., 1805, and sole 

 species named by Lamarck. Children took 

 his type from Sowerby (Genera XIII) which 

 of course is inadmissible. 



235 99 Limax L. rufus (Idem. Linn.) 



§Same in Lk. Syst. 64. Ferussac, however, in 

 1819 subdivided the genus and took L. anti- 

 quorum, Fer. [=maximus, Lin.] as type of 

 Limax, and rufus, Lin. [ = cnipiricorum, Fer.] 

 as type of his new genus Arion. This alloca- 

 tion stands.
