delicate pale pink. The spire too is peculiar, on account of the few

There is a non-adult variety of this species, which does not ex-

 Shell subfusiform not rimate, white, dotted with brown beneath 

 the sutural hne and with a series of brown dots or (in other word,) 

 an interrupted line around the middle, the dots being situated u 

 above the interspaces between the nodules, which form a series a 

 htte below the middle of the whorls. The lower half of the body- 

 whorl dark brown ; and a spot of the same colour stains the shell at 

 the superior sinus ; the apex is also brown. Whorls ten, broadly 

 concave above, and somewhat acutely noduled below ; nodules eleven

 This shell is very distinguishable from its congeners, on account of 

 the peculiarity of its painting, and the series of sharpish tubercles 

 enci cling the whorls. I have much pleasure in naming it after 

 Capt. Wilmer, its discoverer. 8
