 Hab. — Coast generally. 



Obs. — This species varies greatly in shape, from a somewhat 

 conical to almost globose form ; its chief distinguishing characters 

 are, the blood red callosity of the columella, dark interior, and 

 greyish coloured exterior. The callosity only partially covers the 

 umbilicus in the type, but entirely covers it in some examples 

 from Western Australia = N. melastoma, Swainson, and some 

 examples from New South Wales show a medium development 

 in this respect.
