(Plate xlii., fig. 14.) 



Shell elongate-conic, very solid, contiacted at the base, constricted 

 and channelled at the suture, last whorl about half llie total length ; 

 eleven whorls, including the protoconch. Colour pale ochraceons-bulf, 

 aperture lighter. Sculpture : — Last whorl with thirteen, penultimate 

 with four, and earlier whorls with three prominent spiral keels, the 

 furrows between which carry faint radial striae, and sometimes a small 

 interstitial thread. Aperture: — There is a thin callus sheet on the inner 

 lip, and a solid callus plug at the angle of the aperture ; outer lip simple ; 

 sinus a semicircular notch with reflected margin ; canal short, open, and 

 slightly recurved ; deep within the throat are five revolving raised threads. 

 Length 14 mm., breadth 5 mm. 



This is deceptively like Tarrls hrevicavdata, but diffei's in the essential 

 character of the peripheral carina, being single instead of double ; it is 

 besides smaller, more slender, with a shorter canal, and the whorls divided 

 by a deeper suture. I have received a specimen of T. deceptn'x labelled 

 "P?e«. hijnhntn Reeve, Philippines." 



Huh. Queensland : — 80 fathoms, Darnley Island (type, Braziei').
