The identity of l.amarckV, spei^ies .“oems to be obvious though hitherto 
overlooked. His descriidion reads; “B. testa ovata, ventricosa, jierforata, 
longitudinaliter striata, siptalide alba; spira obtusiuscala ; labro margine 
subrefiexo. Habile dans la X'ouvelle llollande. Mon cabinet. Longueur, 
jires d’un ponce.’’ 
This agrees very wc'll tvith the Shark Bay shell, the words “ventricosa 
. . stjualide alba . . spira obtusiuscula” being characteristic of that form. 
Perussae had jiretiousjy named the shell costulatus. and Lamarck re.jected 
this, renaming it injlatiis, but unfortunately the latti'r had been previously 
used by Olivier, so that renr sae's name comes into u e. .\s localities 
Fernssac gave King George’s Sound and Sharks Bay, and though the fornun' 
locality has b('en aiaepted for Lamarck's iiiflalus, the lignre given by Delessert 
is of the Shark Bay shell. This figure measures 27 mm. by 17 nun., and 
Shark Bay shells \ ary from 2() to 28 mm. by 17 mm., smaller ones 21 nun. by 
16 mm., and 2] mm. by 15 mm. Smith’s figure of onslowi measures 24 mni. 
by 16 nmi., and Cox’s measurements of oitslowi are equal to 21.2 mm. by 
15 mm. 
Peron records from Bernier (and other) isiand(s) in Shark Bay: “Two 
species of land shells extremely numerous, but all dead, occupied great
