The apex is coarsely wrinkly striate around the upper part of the whorls, 
the lower rcticulately i)ittcd, coiisistiii" of two full whorls, the adult sculpture 
abruptly forniiug’ tliereafter, almost a varix intervening. 
The oolumella is strongly reflected, hut does not hide the umbilicus, and 
joins the outer lip, which is thin, by means of a glaze across the body whorl, 
almost freeing- the mouth. 
Length of figured shell, 27 mm. ; bi-eadth 12 mm. 
The locality is in th(> annual rainfall 10-15 inches bolt.

This niagnilieent species stands alone in its large size, its white colour, 
and its solidity. The ajiex is regularly punctate, the scul])ture is of rough 
radials crossed on the earlier whorls by fine concentric lines, the cross sculpture 
vani.sliing on the shoulder of the last whorl. The columella is broadly 
reflected, concealing an open umbilicus, and the outer lip is thin. The spire 
is about the same length as the aperture. The shell figured measures 60 mm. in 
length by 35 nim. in breadth. Odd speeimens ai-e known from Norseman, 
Duiidas, Salmon flnras, Balladonia, Esjieranee Mallee Belt, and it thus seems 
to be an inhabitant of the drier inland belt and not coastal although all the 
early collected speeimens are labelled King George’s Sound.
