NO. 17 Lamarck's genera of shells — kennard et al. 37 



Genus Type & Synonym 



A. argo 



§Lk. Prod. 79 cited A. argo, Lin., but in Syst. 99 

 changed the name to A. sulcata, reverting, 

 however, in the Hist, to argo. Mft. ii, 7 

 adopted the synonymic A. sulcata. By typo- 

 graphical error the generic name appears 

 under his figure in some copies as "Aargan- 

 nota." 

 253 166 Octopus [No shell.] 



§[Type Octopus vulgaris, Lmk.] 



253 166 Loligopsis [No shell.] 



§ [Lamarck's generic name for sole species L. 

 pcronii dates from 1822 and is anticipated by 

 Lcachia, of LeSueur, 1821.] 



254 167 Luligo L.zmlgaris (Sepia loligo. hinn.) 



I Genus originally founded by Schneider, 1784, 

 who mentions in the text L. Jiiaxima, but type 

 is obviously the Sepia loligo, Lin. Lamarck in 

 1798 employed the same generic name and 

 amongst his species is L. inilgaris, a synonym 

 for Sepia loligo, Lin. 

 254 167 Scphi 



256 169 S. officimilis (Idem. Linn.) 



§Same in Lk. Syst. 59. 



257 T70 Carinaria C. vitrea {Patella cristala. Linn.) 



^Genotype, Lk. Syst. 99, is C. vitrea, n.n. for 

 Patella cristata, l^\n. = A rgoiiau la vitreus, 

 Gmel. The correct type name is, therefore, 

 Carinaria cristata (Lin.). 



258 171 Ptcrotrachca [No shell.] 



§[Lk. Syst. 6r cites P. coronata, Forsk.] 

 258 1 71 Phylliroc [No shell.] 



§1 Sole species cited by Lamarck is P. hucepha- 

 lum, Peron. Genus founded in 18 10 by Peron 

 and LeSueur. but species cited by them in 

 vernacular.]
