242 RECORDS OF THE AUSTRALIAN MUSEUM. 
INQUISITOR LACERTOSUS sp. nov. 
(Plate xliv., fig. 32.) 
Shell solid, biconical. Whorls six, of which two compose the proto- 
conch. Colour salmon-buff, ribs cream; a few scattered ferruginous dots 
and large square ferruginous spots in the intercostal spaces. Ribs low, 
tubercular, projecting in an acute angle from the shoulder; nine on the 
last whorl. Sometimes elevated crescentic lamelle extend from these 
ribs to the suture; other lamelle continue as fine growth lines across the 
shell. The spirals are faint threads, evanescent on the shoulder and 
prominent on the snout. Of these there are about forty on the last 
whorl, twelve of which are posterior to the angle. Aperture simple and 
unfinished in the only example available. Length 13 mm., breadth 7 mm. 
Hab. N.S.Wales:—50 fathoms, off Point Plomer (type, self). 
INQUISITOR LASSULUS sp. nov. 
(Plate xliv., fig. 33.) 
Drillia varicosa Brazier, Proc. Linn. Soe. N.S.W., 1., 1876, p. 152 (not 
Pleurotoma varicosa Reeve). 
Shell of moderate size, solid, rather glossy, fusiform. Colour buff, 
chequered with ochre-red, disposed irregularly, though alternate segments 
of red and buff on the subsutural cord seems a constant feature; usually 
the snout, the fasciole, and a narrow supra-basal zone are buif, while the 
intercostal spaces and a broad basal zone are red. Whorls ten, of which’ 
two include the protoconch. Sculpture:—A prominent undulating cord 
runs beneath the suture, and is followed by a rather narrow fasciole with 
a median groove; the ribs may, or may not, swell at irregular intervals 
into varices—they are stout, perpendicular, discontinuous, persistent on 
the last whorl, and reach to the base; they are set at about eleven to the 
whorl; spirals are flat-topped cords, their width apart, more prominent in 
the interspaces than on the ribs, their interstices and sometimes them- 
selves crossed by a secondary sculpture of fine radial threads, excluding 
the subsutural spiral; there are fourteen on the last whorl, and two or 
three on the earlier whorls. Aperture:—Mouth narrow, last varix twice 
its breadth behind the edge of the lip; sinus open, wide, and deep; 
columella straight, inner lip with a raised margin ; canal produced and 
recurved. Length 15 mm., breadth 5 mm. 
Compared with J. varicosa, for which Brazier mistook it, this species 
is shorter, stouter, and with less and fewer varites. J. sterrha is twice 
the size, more brightly and differently coloured, with broader, rounder, 
and closer ribs. J. spaldingi is more like it, but apart from the different 
colour scheme. I. lassvlus is smaller, with more prominent ribs, and may 
be distinguished especially by the conspicuous and chequered subsutural 
ridge. 
Hab. Queensland:—8 fathoms, Weary Bay (type); 15 fathoms, 
Palm Island (self); 20 fathoms, Darnley Island; 16 fathoms, York Island ; 
11 fathoms, Palm Island (Brazier); 20 fathoms, between Cairns and 
Endeavour Reef (McCulloch).
