This species may be distinguished from D. dentifera and ino7iodonta^ by its strongly 

 truncated spire and b)- being attenuated at the upper part, monodonta being more cylindrical, 

 dentifera regularly oval. One specimen is slightly worn, but has the tooth-like fold more con- 

 spicuous, than that which has served for description. Both specimens are empty shells, consequently 

 it is not certain that they have lived at the recorded depth.

Stat. 4. Djangkar (Java). 9 M. Coarse sand, i Spec. 



Shell subcylindrical, slightly narrower above then below, truncated above, upper part 

 of sides and base rounded; rather strong, white, partly covered by a dark brown epidermis. 

 Sculpture consisting of hair-like growth-striae, stronger at irregular intervals, and of numerous, 

 irregular, waved, spiral striae, more crowded at some places, stronger near the base, where they 

 have the appearance of lirae. Spire deeply umbilicated, bordered by a sharp keel. Aperture 

 elongated, narrow above, dilated below, its upper margin being the continuation of the um- 

 bilical keel, a little ascending, outer margin at first rounded above, then nearly straight, broadly 

 rounded below and at the base of shell. Columellar side nearly straight at body-whorl, rounded 

 above, with a narrow but conspicuous layer of enamel ; columella thick, rounded, slightly con- 

 torted, nearly straight above, concave below, with an umbilical slit behind it.

I know no East-Indian species which is nearly allied.
