BODY whitish, minutely speckled with flake-white [purplish- 

 white (F. &H.)] : pallial tube cylindrical and long, projecting 

 in front : tentacles short, with blunt tips : eyes large, on the 

 thickened end of stalks which are two -thirds the length of the 

 tentacles : foot very long and narrowish, truncated or indented 

 in front, with a rather large flap or auricle at each corner, 

 bluntly pointed behind. 



SHELL cylindrical, and pointed at each extremity, solid, 

 nearly opaque, of a rather dull aspect : sculpture, strong, broad, 

 rounded, and rather prominent longitudinal ribs, from 7 to 9 

 on each of the last three whorls ; they extend to the base, but 

 not quite to the suture, the space below which is strongly and 

 spirally sculptured; the whole surface (except the apex) is 

 covered with thread-like spiral ridges, which are finely and 

 closely reticulated by microscopic longitudinal striae, making 

 the crests of the principal ridges (especially of those below the 

 suture) beaded and the surface roughened; these ridges are 

 more or less wavy and of different sizes, the larger and 

 more conspicuous numbering about 15 on the body-whorl, 

 5 or 6 on the next whorl, and decreasing upwards ; the third 

 whorl has several minute curved striae in the line of growth, 

 their interstices being pitted, or the striae granulated, by the 

 intersection of four or five equally minute spiral striae ; the 

 top whorls are smooth and glossy : colour yellowish- white, 

 orange, or occasionally deep reddish-brown ; paler specimens 

 sometimes exhibit traces of a broad orange band below the 

 periphery : spire turreted, and gradually tapering to a some- 

 what abrupt and blunt point : whorls 8-9, moderately convex, 



* Short-mouth.
