This shell is nearly allied to B. carnea, but is rather smaller, 

 more oblong, less ventricose, of an orange colour, and not 

 paler on the back or base. Lamarck under the name of 

 Ovula hordacea, has described another species, which he 

 says is nearly similar, but differs in being still more cylindri- 

 cal, and a little angulated on the back towards the anterior 

 end. 



birostris. 6. Shell beaked at both ends, and the 

 outer lip thickened ; beaks long and smooth.

The following is Linnaeus's description of this species : " It 

 resembles B. Volva, but is much smaller, and of the size of 

 a horse-bean ; is less distended, smooth, and of a whitish 

 flesh-colour. The beaks are equal, smooth, nearly of the 

 length of the body, obliquely truncated, and one of them a 

 little ascending. The outer margin thickened. Aperture 

 nearly equal, but broader towards the beaks." Though 

 Kaemmerer has placed it as a Variety of B. Volva, yet both 

 he and Born consider Martini's figure 217 to be the Lin- 

 nsean B. birostris, and in the opinion of many Conchologists, 

 it is nothing more than a young shell of that species. 



secale. 7. Shell oblong, sub-cylindrical, acumi- 

 nated at both extremities, and the outer lip 

 very slightly thickened at the margin.
