Diagnosis.—It approaches P. gemmulifera, Hedley, 
Proc. Linn. Soc., New South Wales, 1907, vol. 
Xxxii, part 3, p. 510, pi. maby Nite 44, 
but has a smooth protoconch; any axial _ sculp- 
ture on it, which is very rare, is only a faint striation near 
the upper suture, and close to the abrupt ending of the proto- 
conch, quite different from the ribbing of Hedley’s species. 
The spire-whorls are well rounded, and contain mostly. three 
spirals. It is a larger species. Gatliff and Gabriel have 
recorded this shell for Victoria in Proc. Roy. Soc., Victoria, 
1910, vol. xxiii. (N.S.), part 1, p. 89, as Coluwmbella gem- 
mulifera, Hedley, noting the differences as varietal, which T 
regard as specific. 
Variations.—When alive the shell is translucent shining 
uniform light-amber colour, the protoconch rather darker, 
or a broad whitish band may encircle the middle of the 
whorls, fading out before reaching the aperture; the proto- 
conch may be purple; generally the shell is translucent or 
opaque-white, probably from bleaching. Sculpture.—The 
axials and spirals may be well marked, but the tuberculation 
obsolete, giving a latticed pattern. There may be two spirals 
in the first spire-whorl; the back one may then split behind 
into a third, which gradually enlarges, and this may in the 
fourth whorl give off another one behind. There may rarely 
be three spirals in the first spire-whorl, and four in the 
second.
