This species has much resemblance with the preceding one and with M. obelisctis Reeve, 

 but is easily distinguished by its very beautiful, elaborate sculpture; the smallest specimen, though 

 full-grown, as may be seen by its peristome, has the columellar plaits less developed. I

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

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

 had the kindness to send for comparison. 



9. Mangilia septemcostata n. sp. PI. XXVIII, iig. 11. 



Stat. 51. Madura-bay. 69 — 91 M. Fine grey sand, 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 

 7Y2, of which 2Y0 form the convexly-whorled nucleus, of which about the first whorl is smooth, the 

 other ones 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 

 costal 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 characters seemed to be peculiar enough 

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

 afterwards procured.

Stat. 260. Near North point of Nuhu Jaan, Kei-islands. 90 M. Sand, coral and shells, i Spec. 



Shell thin, of a hyaline, whitish colour, with the points of the ribs a little more remote 

 from lower suture, but otherwise so much the same in number of ribs and in other particulars 

 of sculpture, that I think this form has only varietal rank, perhaps depending on greater depth. 

 It is likewise juvenile.
