 characterized by its straight cylindrical form, depressed 

 spire, flexuous line painting, and violet interior.

Varietas. 0. liigubris, Duclos. 

 Hub. North Au.stralia; Jukes. 



A species of very solid growth, prominently distin- 

 guished by the very deep violet colouring of the interior. 

 The specimens Fig. c, d represent the typieal state of the 

 species. Fig. a, b represents a dwarf variety (0. lugitbris, 

 Duclos), in which there is an unusually copious stipply of 

 the dark livid-olive paintiug.

Lamarck, Anim. sans vert. (Deshayes' edit.) vol. x. p. 015. 



Eab. Island of Negros, Philippines (in sandy mud at hiw 

 water) ; Cuming. 



Several species of the genus are characterized h\ a 

 tinge of red at the base of the columella, but in this tlie 

 whole of the columella is of a uniform blood-red, and this 

 colour not unfrequently appears in the callosity of the spire 

 and alouii' the outer lii).
