whorl with the subsutural nodulated band, anterior to this the 
excavated groove, followed by its angle of junction with a uni- 
form, slightly convex surface. The longitudinal plice may 
extend almost to the base, or may become obsolete at the peri- 
phery ; and generally become less marked towards tke aperture 
in older shells. Spiral engraved lines 13 to 15, equidistant, most 
marked at the base, so as to form there about five obliquely 
rounded spiral lire. Aperture obliquely elongate-ovate, con- 
tracted behind between the subsutural band and a smal! columel- 
lar callus, minutely canaliculate. Outer lip simple, thin, slightly 
sinuous, internally seven narrow spiral plicate teeth, equidistant, 
extending to within a line of the margin. Columella nearly 
straight, concave at the base, where the callus is thick and closes 
the umbilicus ; a rather broad spiral plica lies over the situation 
of the continuation backwards of the varix of the notch, it may 
be simple or bifid or three or four divided. Notch well marked, 
with minutely everted margins, varix of notch valid, and bounded 
above by a definite slightly elevated edge continuous with the 
sharp right margin of the notch. Ornament, rusty-brown or 
deep mahogany, with bluish-white patches composed of several 
oblong spots disposed between the engraved lines, most numerous 
just above and below the angulation and towards the base. In 
these areas the brown and whitish spots may be almost regularly 
articulated, or so disposed as to form longitudinal brown flames. 
Living shells are often brightly glistening, dead shells uniform 
dull rusty brown. 
Length, 25 mm.; breadth, 10 mm.; spire, 14 mm.; aperture, 
10 mm. long, 4.5 broad. 
Habitat.— Along the whole coast of South Australia, at low 
water. Eyre’s Sandpatch, West Australia, large specimens. 
Remarks.—This shell has been known in South Australia as 
Cominella suturalis, A. Adams see list of Aquatic Mollucea of 
South Australia, D. J. Adcock, 1893. But that shell is a 
Nassaria, and as figured in Tryon’s Man. of Conch., pl. 84, fig. 
542, and as examined in a specimen sent to me identified by G. 
B. Sowerby, is a shell quite unlike the South Australian form. 
The dentition of Vassaria, as given in the Man. Vol. 3, pl. 27, 
fig. 34, shows a six-cusped rachidian tooth, while our shell has 
only three cusps. I had identified it as Josepha Tasmanica, Ten. 
Woods, Pros. Roy. Soc., Tasmania, 1878, p. 32, upon which he 
founded his subgenus Josepha ; but it had never been figured, 
and on enquiry it was learned that the type specimens in the 
Hobart Museum had been mislaid, and could not be referred to. 
However, Miss Lodder, of Ulverstone, Tasmania, has lately for- 
warded to me two shells, identical with this Phos Tasmanica. 
They were found without a label among some shells presented by
