Shell fusiformly turreted, solid, white, sometimes with a zone of 
double interrupted chestnut lines near the base of the last whorl, 
similar chestnut markings béing occasionally apparent here and there 
near the upper portion of the whorls; whorls 6, convex, longitudi- 
nally ribbed and crossed with transverse ridges that become sharply 
and prominently nodulous upon the ribs; spire sharp, apex light 
brown; aperture narrowly quadrate; outer lip varicose and denti- 
culated ; posterior sinus moderate. 
Length 23 lines, breadth 1 line. 
Hab. “ Bottle and Glass” rocks, Port Jackson (Brazier). 
A pretty little white species presenting a more or less beaded 
appearance all over, sometimes marked with interrupted transverse 
chestnut lines. 
CLATHURELLA PUSTULATA, n. sp. (Plate V. fig. 14.) 
Shell fusiformly turreted, moderately solid, white, irregularly 
longitudinally flamed with brown on the upper whorls, with two 
broad brown bands on the last whorl ; whorls 6, convex, longitudi- 
nally costate, with about 10 rounded ribs, encircled by about the same 
number of narrow prominent ridges that become slightly nodulous 
at the intersections, the interstices showing, under the lens, very 
faint descending strie ; the lower portion of the basal whorl and 
the pillar strongly granulated; spire sharp; aperture elongately 
ovate ; outer lip thickened and varied behind, dentate within ; 
columella nearly straight above, slightly sinuous below ; canal short 
and open; posterior sinus broad and shallow. 
Length 33 lines, breadth 1} line. 
Hab. Port Jackson (Brazier). 
This species, which is prettily variegated with ash-brown, may be 
at once recognized by the stout granules at the base of the pillar.

Shell fusiformly turreted, solid, fulvous brown; whorls 53, con- 
vex, stoutly and distantly longitudinally ribbed, and crossed with 
prominent erect ridges becoming sharply nodulous at the intersec- 
tion ; spire sharp; aperture narrowly ovate; outer lip somewhat 
flattened and thickened, strongly dentate within; columella a little 
sinuous, with a few small granulations at the base of the whorl ; 
posterior sinus rather broad.
