The only habitat given was South Australia, but Tate’s 
shells almost certainly came from Moonta Bay, as they were ’ 
in a tube with others which T have described in this paper as 
Scutellina alboradiata, sp. nov., and which have been ob- 
tained in numbers at Moonta Bay by Mr. Zietz.

' Shell oval, thin, translucent, narrower in front, about half 
as wide as long, its height less than half its greatest width. 
Apex at the anterior sixth, simple, non-spiral. Numerous 
fine diverging axial strize, with crowded minute sublenticular 
accremental striz. Apex red; sixteen equidistant, pink, in- 
creasing radial rays, each composed of two to four lines; 
white opaque blotches, irregular in shape behind the apex, 
Somewhat concentrically arranged ; a central linear one just 
behind the apex. Spatula shaped as in Patella; fairly dis- 
tinct, margined in front opaque white; behind this pinkish- 
brown, which extends backwards in two  shert diverging 
flames ; between these a white opaque flame extends back from 
the apex of the shell. The rest of the spatula is mottled 
with wavy, opaque, white blotches.
