CONUS PATENS (Plate III., fig. y). Shell thin, light, elon- 

 gately pyriform, white, with a few very faint fulvous markings a 

 little above the middle of the body whorl ; covered by a rough 

 and scabrous but light coloured periostracum. Spire moderately 

 elevated, acute, graduated ; whorls 8, concave, keeled at the 

 angle, without spiral sculpture. Last whorl slightly convex, 

 tapering towards the base ; with slightly waved growth lines, 

 and very faint spiral lirae visible only in parts and under the 

 lens ; the lirae at the base are scarcely more apparent than those 

 on the other parts of the shell. Aperture rather wide, the pos- 

 terior end a little narrower ; outer lip thin and simple, with a 

 deep, rather broad posterior sinus. 



Length 68; width 35 millim. 



Operculum remarkably small for the size of the shell (6 by 2\ 

 \T: :lim "l laminar, slightly scabrous, not regularly oblong, but ex- 

 pandcJ on the right anterior side, with the nucleus inclining to 

 t^ -left. 



Hab. : — Vasco de Gama Pk. bearing N. 10° E. ; distant 13 

 miles ; -^epth, 85 fathoms. Bottom, green sand. Only one full- 

 sized f /ecimen obtained ; but several much smaller ones were 

 taken ai different stations. 



This shell bears some resemblance to C. fulvocinctus, Crosse, 

 bu" it is of a lighter substance, and destitute of the basal lirae 

 which are somewhat prominent in that species. 



Cypr^A Fultoni (Plate IV., fig. 7). Shell depressly pyri- 

 form, with a slight angularity at the sides near the posterior end, 

 produced by a tubercle or swelling on each side ; extremities 

 slightly produced ; pale fulvous variously marked with brown 

 streaks and spots, suffused with dar]-: brown at eacli end, and 

 ornamented with numerous rather large dark brown spots at the 

 sides partly extending over the base ; beaks at the posterior 

 extremity rather wide apart, surmounted by a thick brown callus, 

 completely hiding the apical whorls ; beaks at the anterior ex- 

 tremity closer together and slightly incurved ; back rather de- 

 pressly rounded, obliquely sloping in front ; base slightly con- 

 vex. Aperture of moderate width, with a prominent plait at the 

 base of the columella ; teeth on the left side of the aperture 11, 

 the anterior ones being thick and short, the rest narrower and 

 irregularly placed ; on the right side 1 8, more regular, extending 

 partly across the base, and leaving brown stripes where they 

 become obsolete. 



Length 60 ; width 39 ; height 29 millim. 



Hab. : — South Africa. 



Only a single dead specimen of this striking new species has 

 yet been found. The package in which it came was broken in 

 transit, and the number referring to the locality lost.
