Z. tasmanica Beddome 1882 {Legrandia) (— ’/Adorn legran- 
di late 1894). PI. 1, fig. 12. Oval, radiately ribbed; front 
edge fissured; interior with a shell}- {date extending one-fourth 
the length of the shell. Length 5, breadth 3, height .75 mm. 
Rare; Venus Bay. Corner Point, beach; 35 fathoms west of St.

—Kelso Bay, Tamar River. Tasmania, 17 fathoms). Beddome’s 
description (above) is severely brief. Beacusc of this and the 
absence of actual specimens for comparison. Tate described /.. 
legrandi. at the same time remarking “there <s presumptive evi¬ 
dence that the two shells belong to one species." The following; 
is Pate's description—depressed!)' conical, cap-shaped, delicate* 
elliptic-oblong in basal outline, rounded behind, truncately roun¬ 
ded and deep\' cleft in front, with a narrow sunken fissural band 
extending to the apex; back depressedly convex: white; radial 1 
threadlets, oblique, and concentric ibreadlcts, produce a cancella¬ 
tion of rhombic spaces; margin of aperture, closelv creuulatc- 
serrate: lissural band margined on each side by an elevated, 
rounded keel, which is cremated; scars on lissural band, arched, 
sharp, close but not contiguous; protoconch minute and short* 
hooked and somewhat addressed, almost reaching the posterior 
margin; inside gloss)-, smooth; septum narrowly crescentric (ex¬ 
tending in middle line to about one-fifth and on sides one-fourth 
of length of aperture), much depressed posteriorly (about one- 
half depth of shell) becoming shallower on anterior border. Length 
9.5, breadth 6, height 2. depth of cleft 2 mm. Juveniles have the 
protoconch projecting beyond the periphery, which is a distin¬ 
guishing feature of Z. ladder ae Tate and Mav, from Tasmania, 
but no mature South Australian specimens are referable to that 
species.
