Stewart Island, N. Zealand, 24 fms. (Hutton) ;

zmula, Angas (PI. 12, fig. 37), is identical.

D. exiuis, Pease. Pl. 15, fig 25; Pl. 12, fig. 32. 
Whorls nearly plane, longitudinally plicately ribbed, the ribs

Shell stouter, the spire shorter, more convex and obtuse than 
in the preceding species, the whorls not constricted above; 
sculpture and coloring same as in D. ewilis. 
Viti Islands. 
Although remarkably similar to D. exilis, the form will, on 
eomparison, readily distinguish it.
