A miniature D. sinistrormi, but having the umbilicus more open, 

 the aperture more nearly round, with less expanded peristome, the 

 whorls rather more convex and fewer by one and a half. The speci- 

 mens from Noumea are a little smaller than those from Nou Island.

D..CROSSEI Pilsbry, n. sp. PI. 3, figs. 10, 11. 



Shell sinistral, umbilicate, turbinate-pyramidal, rather solid, chest- 

 nut brown, whitish at the apex. Surface somewhat glossy, sculptured 

 with irregular growth-wrinkles. Spire high-conic, the lateral out- 

 lines straight or a little concave near the apex. AYhorls G|, some- 

 what convex, the last convex or a little flattened at the periphery, 

 not angular, and but little expanded toward the aperture ; base con- 

 vex ; umbilicus narrow. Aperture very oblique, dark brown or 

 purple-brown within ; peristome white or nearly so, thickened within 

 and on the face, very narrowly expanded; outer lip arcuate, especially 

 near the upper insertion ; baso-columellar lip straightened and dilated 

 above ; both margins thickened at their insertions and connected by 

 a rather strong but transparent parietal callus.

New Caledonia (E. Marie). 



This species stands between D. sinixtrorsa and D. lifixmn. The 

 former is much more openly umbilicate, the last whorl is more de- 

 pressed, much more expanded towards the aperture, the peristome is 

 not so thickened, and the color is much lighter. Compared with D. 

 lifixiiKi, the present species is more elongate, darker, and has a 

 narrowly expanded, thickened peristome. Four specimens, essenti- 

 ally alike, are before me.
