(carinae, straight below. Spire-whorls twelve, sloping, tli3 

 first four with two spiral rows of pearls : in the fifth a lira 

 appears between them, and becomes gradually as large as the 

 others ; the tubercles are large, about twenty in a row in 

 the penultimate, joined by short bars transversely, and by 

 narrower axial bars directed obliquely forwards towards the 

 lower suture. Sutural spaces distinct, as wide as a pearl 

 row ; in the eighth a supra-sutural thread arises, ~iwhich grows 

 distinct and slightly tuberculate. Base flatly convex, with 

 the sutural lira, and two basal lirae ; the first with valid trans- 

 versely oval tubercles, joined by very broad axial bands to 

 much lower tubercles in the second, and by vanishing bands 

 to the nearly smooth third lira. Aperture round, pinched 

 at the suture into a sinus, and with a short well recurved 

 €anal in front ; outer lip thin, simple, slightly reflected at 

 its margin, retrocurrent at the suture, crossing the colum- 

 ella in front and flattened out over the base of the canal, so 

 as to close it here. The outer lip has eight nodulous spirals 

 on its outer surface, viz., three as on the spire, the peripheral 

 and one basal, and three others intercalated on the body- 

 whorl. Colour, protoconch light-brown, shell white, but for 

 the fifth and sixth whorls which are dark-brown, so as to 

 form a sort of bracelet, whence the name.
