CONUS PATENS (Plate III., fig. ;). 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 tlim 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^ 

 m- Mim ) laminar, slightly scabrous, not regularly oblong, but ex- 

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

 tie left. 



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

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

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

 taken ctt 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 dark brown at each 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 1 1, 

 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 milHm. 



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.
