the South Coast of Australia. 89 
apical angle 65°, of four whorls (besides the pullus); turns 
of the spire moderately convex ; body-whorl obtusely angu- 
lated a little below the suture; whorls of the spire crossed by 
from sixteen to eighteen large obtusely flattened prominent ribs, 
most prominent towards suture, the intervening spaces between 
which vary from rather more, on the spire, to much less than 
their width, on the penultimate whorl ; ribs becoming obsolete 
on body-whorl; sloping angulation of body-whorl and spire 
near suture marked with about ten cord-like subequal spiral 
ridges, with coarse parallel stria between them, the intervening 
spaces twice as wide as the ridges; below or before the spiral 
strize on body-whorl the surface is only marked by the obtuse 
irregular lines of growth, until near the anterior extremity, 
where about eighteen or nineteen spiral ridges similar to those 
near the suture appear, Outer lip moderately arched, ob- 
tusely thickened and reflected; respiratory notch at anterior 
end moderate. Three or four large oblique plaits on pillar, 
the hindmost but one largest ; inner lip thin, glassy, spreading. 
Colour pale brownish creamy white, with acutely angular zig- 
zag, longitudinal, sparse markings of rich raw-sienna brown. 
Length 6 inches 5 lines; proportional length of body- 
whorl =1°.. of penultimate whorl +5, antepenultimate 75>, pre- 
ceding whorl ;4,; length of pullus $5, width of pullus pO> ; 
diameter of succeeding whorl at suture 7/5; greatest diameter 
of body-whorl 335. 
This magnificent Volute was found by Mrs. Roadnight, to 
whom I have had the pleasure of dedicating it, three years 
ago, when I sent a description and figure for publication, 
which seem to have been lost, and a copy of which I now for- 
ward, as I have recently received several inquiries about this 
the most striking form among the many Volutes described of 
late years. In its great size and general aspect it somewhat re- 
sembles the fossil Voluta Hannafordi, M‘Coy*, a fact which 
did not escape Mrs. Roadnight’s notice. It differs, however, 
in being rather more slender, less angulated, without the 
conical tubercles of that species, and having the whorls of the 
spire crossed with narrower obtuse coste. It is not nearly 
related to any recent species known to me. 
Hab. Southern coast of Victoria, the type specimen having 
been found on the beach at the Lake’s Entrance, Gipps Land.
