A REVISION OF THE AUSLRALIAN TURRIDH—HEDLEY. 309 
and another on the left; there are no other teeth within either lip; on 
the columella is a thick and smooth sheet of callus. Length 5 mm., 
breadth 2 mm. 
There is a species from the Persian Gulf which, though rather larger, 
seems to be otherwise identical, and which has been distributed as Munyilia 
fairbanki and as Mangilia scitula, neither of which names are applicable. 
I have also seen P. bipyramiduta, from the Isle of Pines, New Caledonia. 
Along the Great Barrier Reef this species seems common and generally 
distributed. 
Hab. Queensland :—5 to 8 fathoms, Murray Island (type); 4 to 14 
fathoms, Albany Passage; 5 to 10 fathoms, Hope Island; 15 fathoms, 
Palm Island; 4 fathoms, Van Diemens Inlet, Gulf of Carpentaria (self) ; 
20 fathoms, off Endeavour Reef (McCulloch).

Mangilia caleata Hedley, Proc. Linn. Soc. N.S.W., xxxiy., 1909, p. 456, 
pl. xliv., fig. 90. 
Hub. Queensland:—5 to 10 fathoms, Hope Island (type); 5 to 8

PSEUDORHAPHITOMA CRUDELIS sp. ov. 
(Plate li., fig. 133.) . 
Shell small, rather solid, lanceolate, constricted at the suture, and 
contracted at the base. Colour uniform pale buff. Whorls eight, of which 
three constitute the protoconch. Sculpture:—The ribs are seven to a 
whorl, slightly oblique to the axis, low and round-backed, decreasing in 
prominence as growth proceeds, continuing from whorl to whorl; the 
spirals are numerous, closely-packed, grained, unequal threads extending 
from the suture‘to the base; on the upper whorl two spirals predominate 
to form a double keel, but these gradually decrease, so that when the last 
whorl is reached the discrepancy between major and minor spirals has 
nearly disappeared. Aperture:—Mouth narrow, the varix equal to the 
preceding ribs, and not rising above the plane of the suture; its outer 
limb evenly striated; within the aperture a tubercle arises beneath the 
sinus; below that and under the free edge of the limb are four minute 
denticules; columella perpendicular ; sinus small and shallow ; canal short 
and open. Length 5:5 mm., breadth 2 mm. 
This is like a miniature Mangelia multigranosa Schepman. 
Hab. Queensland:—4 to 14 fathoms, Albany Passage (type, self).
