(Plate xix., fig. 25.) 



Shell solid, oblong, subcylindrical, rounded at each 

 extremity. Colour, the upper part of each whorl is dull white, 

 the lower slate-purple, the anterior extremity is again dull 

 white, the dark band on the median third of the last whorl 

 fading away before reaching the aperture, apex brown. 

 Whorls five, rapidly increasing, wound obliquely the last two- 

 thirds of the total length. Sculpture : The earlier whorls are 

 smooth, the later bear fine incised spiral grooves, of which the 

 last has about thirty, the penultimate eighteen, and the ante- 

 penultimate twelve. Occasional growth striae cross the shell 

 obliquely. Aperture pyriform. Columella excavate, outer 

 lip grooved within and bevelled to a sharp edge. Length 4*5, 

 breadth 2 mm. 



Compared with O. glomerosa, Hedley,i from Masthead 

 Island, this is far larger, more solid, comparatively broader 

 and darker in colour. It is probably the species reported by 

 Messrs. Gatliff and Gabriel^ from Port Albert, Victoria. 



Hah. — Two specimens from off Devonport, Tasmania
