showing here and there narrow, transverse, somewhat diaphanous 
lines of a dark colour, very finely longitudinally striated with the 
lines of growth; whorls 5, very convex, the last inflated; sutures 
impressed ; aperture subcircular ; outer lip simple, arcuate; margins 
united by a broad, flattened, whitish caHus, which is expanded over 
the columella and somewhat produced at the base. 
Operculum horny, paucispiral, with the nulceus subcentral. 
Long. 4, lat. 23 lin. 
Hab. Shores of Lake Eyre, South Australia (Waterhouse).

(Plate XXVI.) 
Murex BRAZIERI, n. sp. (Plate XXVI. fig. 3.) 
Shell elongately ovate, solid, light brown, tinged with brownish 
purple on the columella and within the aperture, variced with six ir- 
regular varices ; whorls 5, somewhat excavated and flattened above, 
the upper ones encircled with two, and the last with five strong erect 
ribs, some of which are double, crossed longitudinally with squamate 
ridges throughout, which are nodulous on the ribs, and become more 
foliaceous towards the base ; aperture ovate, outer lip dentate within ; 
canal half the length of the aperture, slightly recurved. 
Long. 4, lat. 2 lin. 
Hab. Dredged outside Port-Jackson Heads in 20 fathoms (Bra- 
zier). 
This little species is somewhat allied to Murex mundus of Reeve. 
PeRISTERNIA BRAZIERI, 0. sp. (Plate XXVI. fig. 4.) 
Shell fusiform, moderately solid, light yellowish brown, longitu- 
dinally ribbed with about eight broad ribs, tumid above, which become 
obsolete towards the anterior portion of the basal whorl, crossed 
with numerous fine, impressed, concentric lines, especially on the 
upper whorls ; whorls 63, slightly flattened below the sutures ; sutures 
irregularly impressed ; aperture narrowly ovate; outer lip with a 
small blunt tooth anteriorly ; columella arcuate, with a slight callous 
projection close to its junction with the outer lip; canal moderate, 
very slightly exserted and recurved. 
Length 1 inch, breadth 5 lines. 
Hab. Near Redbank River, New South Wales (Brazier). 
The tooth-like projection just inside the outer lip, at the upper 
portion of the canal, is only present in fully adult specimens. The 
slight fold in the columella, characteristic of Peristernia, is either 
absent or but very faintly developed in the present species.
