INQUISITOR FIBRATUS sp. nov. 
(Plate xli., fig. 27.) 
Shell solid lanceolate. Colour uniform dull white. Whorls ten. 
Sculpture :—Except where interrupted by the spirals, the shell is over- 
run by very close microscopic radial lamelle, a series of which rise along 
the suture and curl into arched scales; these crowning the summit of each 
whorl give a distinct recognition mark to the species; this crest of scales 
is underlined by a stout undulating cord; though excayate out of the 
general contour the fasciole is not well differentiated, it 1s sculptured by 
radial lamelle and traversed by two or three spiral threads; on the last 
whorl, anterior to the fasciole, run about sixteen rather flat-topped spiral 
lyvee, about twice their own breadth apart, between which one or two 
minute interstitial threads may occur; on the penultimate are four such 
spirals; wave-like ribs are set at about thirteen to a whorl, interrupted 
by the fasciole, but continuing to the base and ascending the spire 
perpendicularly. Aperture:—The mouth is narrow; canal short and 
wide; sinus deeply U-shaped; margin everted. Behind the aperture is a 
varical swelling, followed by a narrow pocket groove, beyond which again
