One living specimen was dredged in 101 fathoms 80 miles 

 west of Eucla. The operculum is shown in pi. xvi., fig. 7, 

 and the radula in pi. xvi., fig. 6. The shell is 50 mm. long 

 by 24 mm. at its widest part, including the varix, with a 

 shortly conical protoconch of five whorls. The first three are 

 very depressed, scarcely rounded ; the last two are convex, and 

 rather rapidly increasing. The first four have two erect, 

 sharp, hair-like spiral threads, at about equal distances from 

 the sutures and each other, and numerous though not closely 

 crowded, oblique similar axial threads. These gradually 

 vanish towards the beginning of the last whorl ; this ends 

 abruptly where the ordinary sculpture of the spire-whorls 

 begins. This consists of a row of large tubercles on the median 

 angle, three rows of tiny tubercles above these and one below. 

 On the body-whorl the last become successively larger, and 

 another row succeeds them further forward, and several rows' 

 of large granules are intercalated. The tubercles are deeper 

 yellowish-brown than the ground-colour, and there are stray 

 axial flames of darker brown and articulated spirals of 

 broken lines or tiny spots of brown. The reflected lip just 

 beyond the varix is very daintily spotted on its inner margin 

 with dark-brown, which clouds also the upper part of the inner 

 lip between its white plicae. The lower half of the columella 

 is white, bordered above by the yellow of the back of the pre-
