Habitat. — North-east Australia (Angas). 



Voluta ellioti, Sow., is treated here as a mere variety, that being the opinion I formed after a 

 careful study of the various specimens in the British Museum.

I have no doubt that Voluta angasii, Sow., should be united to Lamarck's species. At the 

 same time it would appear (teste Angas, he. cit. supra) that there is some difference in form between 

 the shells of this species found in Spencer Gulf, and those found further east, but if any distinction 

 is to be made between the two, the question will arise, which answers to Lamarck's type of the 

 species ? I have not had an opportunity of examining his specimens, nor of consulting his figure in 

 the Annals (loc. cit. supra) ; and in the Voyage of Peron, to whom Lamarck owed his specimens, no 

 indication whence the specimens came is given, but certainly (whatever Lamarck's figures may be) 

 all the other figures which I have quoted seem to represent the broad stumpy form to which Mr 

 Sowerby has attached Mr Angas' name, rather than the long and narrow shell he has called Voluta 

 undulata, Lam. That is why I have put a query to the references given to both of Mr Angas 

 later lists. In that of 1864 he evidently regarded the two forms as belonging to one species.
