Antmat nearly colourless and transparent, tinted rose-colour. 
Operculum small, vermilion at the centre and orange-coloured at the 
margin. 
SHELL small ovate-conical, polished, of a delicate hlac-colour ; spire 
conical, whorls seven or eight, convex, crenulated at the suture, the 
upper ones folded, and the folds intersected by revolving lines, so as 
to render them granular; the last whorl half the length of the shell, 
with a few distant, shallow strize surrounding the base; lip simple; 
columella arcuated, white; siphonal notch sufficiently large, very 
short. 
Length two-fifths of an inch; breadth one-eighth of an inch. 
Found on a coral ledge, at Clermont Tonnerre, Paumotu Islands. 
Very much like N. durida. The animal is represented as very 
active, crawling almost as fast as a fly would run.
