2. Cassis monilifeka, spec. nov. PL XYII. fig. 8. 



Shell ovate, scarcely ventricose ; whorls 5, varices few (1-2) or 

 none ; ornamented with obsoletely nodose, low, round, spiral ridges, 

 and bearing on the superior angle a somewhat moniliform row of 

 tubercles ; spire small, conic ; columellar callus granose ; outer lip 

 thickened and dentate ; columella very tortuous beneath the callus ; 

 canal recurved. 



Allied to 0. abbreviata, Lam. (recent), and still closer to C. diadema, 

 Defr. of the Bordeaux Miocene. 



3. Malea camtjka, spec. nov. PI. XYII. fig. 9. 



Shell ovate, ventricose; whorls 6-7, destitute of varices, zoned 

 by about 16 low spiral ridges; spire short, conic; aperture rather 

 narrow, outer lip thickened, dentate; inner lip sinuate, dentate; 

 columella tortuous, irregularly folded or plaited ; callus thin. 



4. Cassidama subl^vigata, spec. nov. PI. XYII. fig. 10. 



Shell ovate, rimate, striated by transverse grooves which are 

 decussated by numerous fine longitudinal lines; varices scarcely 

 prominent, few; whorls 6-7; spire smaU, acuminate; suture im- 

 pressed; aperture elongate; outer lip forming a varix which is 

 scarcely prominent externally, thickened and strongly toothed in- 

 ternally ; columellar margin covered by a spreading callus, on which 

 are several folds or plaits ; canal short, narrow, slightly reflected. 



Allied to the C. Icevigata, Sow., of the San Domingan Miocene, from 

 which it is easily distinguished by its short spire and larger size. 

 Among recent species it is most nearly related to G. striata, but the 

 shorter spire, among other characters, serves to distinguish it.

10. CONUS GEANOZONATTJS, SpCC. UOV. PL XYI. fig. 5. 



Shell elongate, ornamented with numerous (18) transverse nodose 

 ridges, and longitudinally striated by lines of growth, which are 

 most distinct in the sulcations between the ridges ; uppermost keel 

 or ridge on the angle of the whorl bearing larger tubercles ; spire 

 elevated, acuminate.
