Genus 10. SCAPHULA. 



Shell ovate, spire conical, sutural groove open to the apex ; 

 aperture ovate; inner lip rather expanded, thickened, defined, 

 smooth, with two small plaits in front ; anterior belt very narrow. 

 Foot (Oliva biplicata or auricularia ?) rather short, about the 

 length of the shell, broad, much dilated on the sides and covering 

 the whole of the shell ; the front lobes very large, broad, oblong, 

 rounded on the sides. Head hidden ; tentacles none ; eyes none. 

 Operculum none. Animal pale grey-brown, not spotted.

Though M. D'Orbigny in his text correctly described Oliva 

 auricularia of Lamarck, yet in his figiire of the animal he repre- 

 sents the shell of Oliva biplicata, which does not even answer 

 to the character of the genus to which he refers it ; M. Deshayes 

 has referred both animal and shell to that species (see Lamk. 

 Hist. ed. 2. x. 634). 



M; Duclos to obviate the inconsistency — on what authority I 

 do not know — in his enlarged copy of M. D'Orbigny's figure of 

 the animal, places on it a figure of the shell of the true Oliva 

 auricularia of Lamarck ! 



It must be left to succeeding naturalists to discover if the 

 animal figured by M. D'Orbigny is that of O. biplicata or O. 

 auricularia. My genus Scaphula was established on D'Orbigny's 

 account of the animal.

 coloured.
