The shell is somewhat like that of N. limatula but longer, 

 broader and usually with but 4% 5 whorls. Shell compact, 

 broadly ovate to globosely ovate, antique brown to buckthorn 

 brown, the lower whorls indistinctly, minutely striate, the 

 strife and their interstices covered with microscopic, irregular 

 hair-like wrinkles. Spire with convex outlines; whorls con- 

 vex, separated by a rather deep suture. The embryonic 

 whorls are microscopically punctate with a few indistinct 

 spiral lines just above the suture; last whorl slightly swollen 

 just back of the aperture and scarcely flattened over the palatal 

 plicae. Aperture irregularly triangular, with broadly rounded 

 angles, lip-insertions scarcely converging. Angular lamella 

 short, lamella-like, rather widely separated from the parietal. 

 Parietal lamella long, strong, and nearly perpendicular to the 

 parietal wall; columellar lamella very short, deeply seated, 

 horizontally entering, and slightly slanting downwards notice- 

 ably turned upward at the inner end, and in old specimens 

 continued up the columella as a low callous ridge. The two 

 palatal plicae are very short, not approaching the peristome, 

 nearly parallel and rather widely separated. 



Length 1.78, diam 1.15; apert,, greatest length 0.73 mm.; 

 5 whorls. 



Length 1.53, diam. 1.1 ; apert., greatest length 0.7 mm. ;

This species is most easily distinguished from N. limatula 

 of Maui by the much shorter palatal folds; from N. sub- 

 centralis by its broader and more ovate outlines, smoother 

 surface, its shorter and broader aperture ; the rather distantly
