MOLLUSCA. 805 



Tvsrbinella LAM. "(species of Valuta L.). Shell turbinate or 

 subfusiform, with aperture terminating in a canal. Columella with 

 three or more transverse compressed folds.

 36, fig. 7, GUERIN Iconogr., Moll. PL 20, fig. g;Turbin. craticulata 

 LAM., Murex craticulalus L., Encycl. meth., Vers. PL 429, fig. 3. With 

 the exception of this species, LINN.EUS in the last edition of the Syst. not. 

 brings the species of this genus known to him to Voluta. The species are 

 numerous and resemble in form either Fusus or Pirula, from which they 

 differ by the transversely striped columella alone. 



Cancellaria LAM. Shell oval or turrite, mostly reticulate with 

 transverse stripes and longitudinal rugse. Aperture ending in a 

 short canal. Columella with transverse folds; labrum furrowed 

 internally.

 17, fig. M, Encycl. meth., Vers. PI. 375, fig. 3, BLAINV. Malacol. PL 22, 

 fig. i, &c. CUVIER regarded this genus as a sub-division of Voluta; 

 DESHAYES is inclined to place it in the neighbourhood of Tornatella. There 

 is no operculum present. Many fossil species from the tertiary formations 

 are known.

Strombus L. Shell turrite, with labrum dilated into a very 

 ample wing excised towards the canal by a sinus. Canal straight 

 or inflected by the columella obliquely outwards. Operculum 

 horny. Tentacles bifid, the internal lacinia conical, the external 

 peduncle cylindrical, oculiferous at the apex. 



* Canal sululate; sinus of labrum contiguous to the canal. Spec, of
