Shell small, fusiform, nodosely plicate, solid, with browu zigzag 

 markings. Sculpture : The protoconch is smooth ; all succeeding spire- 

 whoiis are axially plicate-costate, the costse more prominent on 

 the lower half of the whorls ; on the body - whorl the cost;e, 10 in 

 number, appear upon the slight angle of the whorl, and are continued 

 a short distance towards the base, or they are only forming a row 

 of elongated nodules. Colour light fulvous, variegated by numerous 

 longitudinally waved chestnut lines, so close as almost to form a net- 

 work over the entire surface, but very often arranged in 3 spiral bands 

 on the body-whorl. Spire not very high, conic, slightly turreted, 

 its height about two-thirds the height of the aperture. Protoconch 

 bulbose, of 2 smooth and convex whorls, the nucleus slightly lateral. 

 Whorls 6, the last high, lightly shouldered or convex ; base very little 

 contracted. Suture distinct, but not deep. Aperture elongate, rather 

 narrow, narrowly channelled above, truncated and slightly notched 

 at the base. Outer lip thickened and not reflected, smooth, lightly 

 convex above, arched below. Columella straight, subvertical, pro- 

 duced below into a sharply pointed beak, with 4 oblique subequi- 

 distant plaits. Inner lip thin, broadly spread over the body-whorl 

 and to the slightly elevated fasciole at the base. 



Diameter, 23 mm. ; height, 55 mm. (almost typical). Diameter, 

 17 mm. ; height, 46 mm. ( Valuta fusus, Q. & G.). Angle of spire, 

 36-40. 



Animal yellow, finely dotted with red-brown. 



Dentition unknown. 



Hab. Bay of Islands ; off Great Barrier Island, in 110 fathoms ; 

 along the Manawatu coast, thrown up after gales ; Queen Charlotte 

 Sound, in 10 fathoms (" Challenger " Exped.). 



Remark. The species is living in deep water, and apparently is 

 not so common as F. arabica. 



Maori. Kaon (fide Quoy and Gaimard). 



Fossil in the Miocene and Pliocene.
