509. S. funictdata and S. diadema, Avith their congeners, should be removed from

670. Dr. Gould dissents from the affiliation of this shell to the "West .Vfrican species 

 on the ground that "he can separate the African from the Pacific shells us fust 

 as we can hand them to him." So easily can any ordinary natural st separate 

 conspecific British and McditeiTanean specimens, or Mazatlan and Panama 

 specimens. It is not found in the West Temperate fauna ; the "var. Ca!i- 

 furnica " being the ordinary type from the Pacific Islands, which is much 

 more entitled to be regarded as distinct than are the West American forms. 



572. Is shown by perfect Cape St. Lucas specimens to belong to a natural group 

 of species, resembling flattened, perforated Phasiunellce, to which the name 

 Eucosmia may be given. 



6S0. Appears under genus " Lagena, Klein,"* in Mus. Cuming; the Argobuccinit 

 cancellatum, Oregonense, &c., having received a new name, Pricne, 11. & A.Ad. 



CS9. This belongs to Closia, Gray, = Voltdella, Swains., non D'Orb. 



* The names of Klein in his 'Tentamen' and ' Lucubratiuncula,' 1773, are not entitled 

 to precedence (according to the Brit. Assoc, rules), because he evidently did not adopt the 

 Liiuiean mode of binomial nomenclature. Wliat he calls a " genus " answers more to tlie 

 modern idea of chapter or section. By chance, some of his name* are allowable ; but, if 

 used, the genus must be regarded as that of Adams, Gray, Mbrch, or other writer who 

 di'fines it. The following will serve as illustrations of Klein's " genera" — " Sol, Luna, 

 Stella, &c. ; Auris, Anas, Tigris, Pes-anserintis, Tuha-phonurgica, Coohlea-lunaris, 

 Cochlea-eeelata, &e. ; Buccinum-lacerum, Buccinunt-muricatun. Thema-musicvm, &c.;

 Conrha-TpiXojio'i ; " and, in p. 167, " Musculus-polylepto-ginglgmus," under which re- 

 markable .^ewer/c name is given as the first species " Arca-No<B." According to the now 

 fashionable transformation of nialai'ologioal nomenclature into a branch of archteological 

 rcieai'ch, under pretence of justicij to ancient writers, the L'theito uuivciially understood
