Inquisitor lacertosus sp. uov. 



(Plate xliv., fig. 32.) 



Shell solid, biconical. Whorls six, of wliieh two compose the proto- 

 conch. Colour salmon-bui5, ribs cream ; a few scattered ferruginous dots 

 and large square ferruginous spots in the intercostal spaces. Ribs low, 

 tubercalai', projecting in an acute angle from the shoulder ; nine on the 

 last whorl. Sometimes elevated crescentic lamella3 extend from these 

 ribs to the suture ; other lamellae continue as fine growth lines across the 

 shell. The spirals are faint threads, evanescent on the shoulder and 

 prominent on the snout. Of these tliei'e 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 ram. 



Hub. N.S.Wales: — 50 fatlioms, off Point Plomer (type, self). 



Inquisitor lassulus sp. uov. 



(Plate xliv., fig. 33.) 



Drillia varicosa Brazier, Proc. Linn. Soc. N.S.W., i., 1876, p. 152 (not 

 Pleurotoma varicosa Reeve). 



Shell of moderate size, solid, rather glossj^ fusifoi-m. Colour buff, 

 chequered with ochre-red, disposed irreguJarlj-, though alternate segments 

 of red and buff on the subsutnral cord seems a constant featui'e; usually 

 the snout, the fasciole, and a narrow supra-basal zone are buff, 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 vai'ices — they are stout, perpendicular, discontinuous, persistent on 

 the last whorl, and reach to the base; they are set at about eleven to the 

 whorl ; spiials 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 stiaight, inner lip with a raised margin ; canal produced and 

 recurved. Length 15 mm., breadth 5 mm. 



Compared with I. varicasa, for which Brazier mistook it, this species 

 is shorter, stoutei", and with less and fewer varices. I. sferrha is twice 

 the size, more brightl}' and differently coloured, with broader, rounder, 

 and closer libs. 7. spuldiugl is more like it, but apart from the different 

 colour scheme. 7. hn'siilKS is smaller, with more prominent ribs, and may 

 be distinguished especially by the conspicuous and chequered subsutnral 

 ridge.
