N. cumingi is imperf orate. The embryonic shell of 3^ whorls 

 is spirally striate and flammulate as usual (pi. 2, fig. 13). The 

 following whorls have nearly obsolete longitudinal folds crossed 

 by crenulated spiral threads, usually coarsest in the peripheral 

 region of the last whorl, finer on the base; the intervals minutely 

 marked with spirally descending, wavy striae (pi. 3, fig. 5, de- 

 tail from back of last whorl, Wailuku specimen). Very often 

 a peripheral thread is stronger, forming a low carina on the 

 front of the last whorl. The surface is lusterless, dull brown. 

 Aperture nearly white with a brown border within the thin, 

 acute lip. The columella is long, straight, heavily white- 

 calloused, and continuous in direction with the parietal wall. 



Length 21, diam. 7.2 mm.; 6 whorls. From Newcomb. 



Length 20, diam. 7 mm. ; 6 whorls. Wailuku. 



Length 19, diam. 6 mm. ; 6 whorls. Wailuku. 



The types were from East Maui, but I see no difference be- 

 tween those before me from Makawao (pi. 3, fig. 4) and the 

 West-Mauian shells (Wailuku, pi. 3, figs. 1-3, 5).
