 Sweden).

Strombus tricornis [Lightfoot, 1786]

 Voiutocorona nobilis (Solander, 1786). — Weaver, 1964, p. 6. 



Troschel in 1866 had already accepted this trivial name, citing it 

 as "Voluta (Aulica) nobilis (Solander)." 



The group Voiutocorona Pilsbry and Olsson, 1954, is being retained 

 as a distinct genus, until its radular characters are known, although 

 it appears to be very close to Aulica Gray, 1847. 



97 "A young specimen of Serpula gigantea or great Oriental 



"Worm Shell, with its Operculum, very rare — Seba, vol. III. 

 Tab. 94." 

 Kuphus polythalamia (Linnaeus, 1766)

Septaria arenaria Lamarck, 1818, p. 437 (not Serpula arenaria L., 



1758). 

 Not Serpula gigantea Pallas, 1766, as Dall erroneously states (1921, 



p. 129). 



176 "Ostrea isognomon L. called Isognoma lignea by S. very rare, 



with an Oyster adhering." 



Isognomon [Lightfoot, 1786] 

 This is the first use of the generic name Isognoma (or Isognomon) . 

 See lots 968 and 3041, wherein the now generally accepted form 

 Isognomon is used. Ostrea isognomon L. ( = 0. isognomum L.) becomes 

 the type of the genus by tautonymy.
