Sassia
garrardi (Beu,
1970)
Description:
Spire whorls sculptured with a row of moderately large, sharp nodules on
the periphery; body whorl with two further rows of nodules below the
periphery, the lower row sometimes poorly defined. Varices regularly
spaced every three-quarters of a whorl, with 4 or 5 nodules between
varices. Entire shell surface covered with closely spaced spiral
threads. Interior of outer lip varies from almost smooth with only a few
denticles at top and bottom, to having 9 denticles over the whole
length. Columella with 3 to 5 plicae at the anterior end. Anterior canal
upturned. Colour light fawn to pale reddish-brown. Covered with a very
thin, pale straw-brown periostracum when alive.
Size:
Up to 35 mm in length.
Distribution:
Endemic to Australia; Broken Bay, NSW, to Eucla, SA.
Habitat:
Taken in 100-300 m. Rare.
Comparison:
Sassia garrardi is similar to, but smaller than, Sassia
parkinsonia, and much rarer. It can be distinguished by the presence
of three rows of nodules on the body whorl, and by having up to nine
fine denticles inside the outer lip, compared with the five large
denticles always present in S. parkinsonia.
