which the whorls are banded with brown and white. There are 20 longitudinal 
tubercle series on the last whorl. 
HEDLEY (1903), in his »Studies of Australian Mollusca», Pt. 7 (Proc. Linn. 
Soc. N. S. Wales) gives the descriptions and figures of several forms of Triphora 
from Australia; the characteristic colouration of the present species distinguishes it 
from them all. SowERrBY (1907, Proc. Malac. Soc. London, Vol. VIT, p. 301, Pl. XXV, 
fig. 8) describes and figures a Triphora fuscozonata from N. Caledonia, with »dark 
brown bands on each whorl; the gem-like nodules... arranged in two prominent 
rows with a narrow intervening crenulated ridge; on the last whorl they are smaller 
and closer, forming six ridges». On the somewhat rough figure one observes that 
both the rows of brown tubercles extend up to the apex, for which reason the 
distinction of this species from the one described here seems to be determined.
