The specimen is not in good condition, being worn and not quite developed, corri 

 pondingly somewhat doubtful, bul it agrees well with a specimen from Bombay, which Mr. Melvill 

 had the kindness to send for comparison.

St.it. 51. Madura-bay. 69 — 91 M. Fine grey s.md, coarse sand with shells and stones. 2 Spec. 



Shell fusiform, with rather long canal, strong, light yellowish-brown, with faint red-brown 

 bands, interrupted by the ribs, one rather broad band, just below suture, the second below the 

 periphery, a third near the base of last whorl, the base of canal being likewise tinted. Whorls about 

 7 1 /,, of which 2 1 /., form the convexly-whorled nucleus, of which about the first whorl is smooth, the 

 other «inrs are closely ribbed; subsequent whorls slightly convex, each with 7 continuous ribs, which 

 have a small sharp point a little above the conspicuous, waved suture and are faintly crenulated, 

 especially on lower part of last whorl; interstices smooth, but for a faint spiral, connecting the 

 .1 points and a few spirals on the canal. Aperture oblong, sharply angular above, with a 

 rather long, narrow canal below. Peristome not developed, probably with a shallow sinus above, 

 columellar margin nearly straight, slightly directed to the left along canal.

Though the specimens are not full-grown, the diameters seemed to be peculiar enough 

 to describe the species; of course the measurements may be altered, il complete specimens are 

 afterwards procured.
