a larger lower palatal are partially concealed by the parietal 

 lamella. The columellar lamella is far within, not visible in 

 a front view. Its inner end turns abruptly downward and 

 along the pillar. 

 Length 1.45, diam. 1.1 mm. 



Section Indopupa n. sect. 



Aperture having a strong angular lamella connecting with 

 the outer lip, and typically a somewhat pitted surface, as in 

 Nesopupa, but the columellar lamella is horizontal or ascends 

 slightly at the inner end. Type: N. filosa (Theob. & Stol.).

As this species has not been figured and the description is 

 somewhat inexact it has been misunderstood by some authors. 

 The record from the Natuna group is uncertain, as Mr. Smith 

 states that his examples did not agree fully with the descrip- 

 tion of moreleti. 



N. moreleti stands close to N. moellendorffi Bttg., which is 

 probably a small race of the same species. As specimens from 

 Cebu are not at hand, and the size is less than in any of the 

 series of moreleti seen, both forms are left standing for the 

 present. 



The outline is cylindric-oblong, the last two whorls almost.
