fusiformis, chem M. Dohrni A. Ad., M . nodilyrata A. Ad., 

 &c, but it differs from all in its large size, attenuate 

 fusiform shape, cinereous-red colour, the gradate whorls 

 14 in number, smoothness of the whorls (to the naked 

 eye), excepting where the spiral acutely noduled corona- 

 tions encircle the upper part of the last five or six whorls, 

 these coronations gradually get fainter, and disappear 

 altogether in the upper whorls, which are many-ribbed, 

 with interstitial transverse liration ; these lirae continue on 

 the lower whorls, many-punctate, and the ribs on these 

 last are fewer and very strongly marked. 



Two specimens, and, I believe, others have been more 

 recently procured by Mr. Townsend, from Muscat. 



(<TTe<j>avovxos, crown-bearing.) 



Marginella (Gibberula) charbarensis, sp. nov. 



(PI. 6, f. 16). 



M. testa oblonga, nivea, politissima, apice acuto undique 

 polito, anfractibus quinque, Icevissimis, unicoloribus, ultimo 

 anfractu recto, apertura angusta, oblonga, labro extus snb- 

 incrassato, involuto, intus planato, Icevi, columella quinque- 

 plicata. 



Long. 8, lat. 4 mm. 



Hab. Charbar, Mekran Coast; also Persian Gulf. 



A snowy-white, unicolorous, vividly polished shell, five- 

 whorled, the last whorl straight, aperture narrow, oblong, 

 outer lip slightly thickened, involute, columella five- 

 plaited. Though allied to M. monilis Phil., and others 

 of the same section, it appears distinct from its congeners. 

 We have seen several specimens, from the two distinct 

 localities as given above, all much alike, excepting that 

 one (Charbar) form has a more sunken spire.
