N. CANDKNs, Hinds. PI. 16, figs. 293, 294. 



Yellowish white, marbled or fasciate with chestnut ; a row of 

 granules below the suture, and close, prickly granulations cover- 

 ing the whorls, caused by the incised revolving lines. 



Length, •'7-'9 inch. 



Marquesas Isles. 



N. CREMATA, Hinds. PI. IG, tigs. 295-300. 



The Avhorls are usually- channeled below the sutures so as to 



separate a single row of nodules, and the close ribs are crossed 



by closer revolving incised lines. The color is yellowish or 



whitish, banded or in-egularly marbled with brown or ash color. 



Length, -75-1 inch. 



Sts. of Malacca, Philipjnnes, Polynesia. 



The taller spire, beaded line beneath the suture, prominence 

 of the longitudinal sculpture, etc., are the distinctive features of 

 this species — which connects undoubtedly with N. albescen.^ on 

 the one hand, and with concinna on the other. Hinds' shell is 

 not adult (fig. 295), and does not exhibit the usual appearance 

 of the species so well as does N. Quoyi, Hombr. (fig. 296), or N, 

 fragum, Hombr. (fig. 297). 



Var. MARGARiTiFERA, Duukcr. Figs. 298-300. 



The longitudinal ribs are narrower, sharp edged, the revolving 

 sculpture coarse, obsolete in the middle of the body-whorl. 

 Besides the brown or chocolate bands or blotches, the surface is 

 numerously spotted on the sides of the small tubercles with 

 chestnut-brown. N. venusfa, Dunker (fig. 2^d ) , N. costellifera 

 A. Ad. (fig. 300), are synonj-ms. 



N. KiENERi, Desh. PI. 16, figs. 301-303. 



Longitudinal ribs prominent, upper margin of each whorl 

 tuberculated, incised revolving lines faint except towards the 

 base, where they cut up the ribs into tubercles ; white with 

 chocolate or chestnut superior and median bands ; surface some- 

 what polished. Length, '75-1 inch, 



Singapore, Polynesia, Tsle of Bourbon. 



The more prominent, less decussated longitudinal sculpture is 

 the chief distinction from N. cremata^ Hinds, the incised re- 

 volving lines from N. raonile, Kiener — which it most nearly
