convex, roundly contracted at the base, with a moderately 
long pillar. 
Aperture obliquely axially rhomboidal, with a distinct 
gutter below the suture, outer lip swollen below the suture 
corresponding with the gutter, then straight or slightly im- 
pressed, anteriorly curved with a shallow infrasutural sinus 
in its border. Inner lip distinct, complete. Columella 
straight in upper half, and bent to the left in its lower. 
Canal open and notched. 
Sculpture, slightly rude axial growth lines; eleven 
spirals from the labium winding round the snout. 
Ornament, amber coloured, with spiral of large opaque 
white spots below the suture; and beneath this a narrow 
continuous white band, a second spiral of larger spots start- 
ing from the back of the aperture. The area between the 
continuous band and the front of this spiral row of spots 
being translucent white. A dark spot on the apex. 
Dim.—Length, 4 mm.; of body-whorl, 2°2 mm. ; 
breadth, 1°8 mm. 
Locality.—Type, 40 fathoms off Beachport, with 1 other ; 
110 fathoms off Beachport, 2; 150 fathoms off Beachport, 1. 
Diagnosis.—It differs from P. atkinson?, Tenison-Woods, 
in its blunt apex; and from P. angasi, of Brazier, and P. 
tenisoni, Tryon, in its swollen whorls and its large peri- 
pheral row of white spots, and especially in 1 the bend of the 
canal. ‘

Some examples are long and narrow, while others are 
short and ventricose; there may be quite valid axial ribs, or 
none, especially in longer individuals. 
There may be a spiral row of white spots immediately 
below the suture. In some this may be present in the upper 
whorls, while the later whorls show a continuous opaque white
