Conus iodostoma. Con. testd subelongato-turbinatd, 

 temii, leviter inftatd; albidii, purpurea pallidisshne 

 tinctd, luteo-fuscescente sparsim et irregulariterpunc- 

 tatd et maculatd ; spird subtilissime sulcatd, apice 

 elato, acuta; aperturd latiusculd, fauce violaceo-pur- 

 pured. 



The violet-mouth Cone. Shell somewhat elongately 

 turhinated, thin, slightly inflated ; whitish, very 

 palely tinged with purple, sparingly and irregularly 

 dotted and blotched with yellowish brown ; spire 

 very finely grooved, apex raised and sharp ; aperture 

 rather wide, interior stained with violet-purple.

Hab. - ? 



This shell has been supposed to have some consider- 

 able affinity with the Conus Janus ; it does not however, 

 in my opinion, exhibit any characters in common with 

 that species, and may at once be distinguished by its 

 tenuity, by its spotted peculiarity of painting, and by its 

 violet-stained mouth. 



Species 21. (Fig. b & c, Mus. Cuming.) 

 (Second notice.) 

 Conus centurio. (For description vide Plate IV.) 



As this interesting species has not hitherto been re- 

 presented in fine condition, I gladly avail myself of the 

 opportunity of figuring a magnificent specimen, which 

 has lately come into the possession of Mr. Cuming. The 

 lip is peculiarly curved, and it presents a marked emar- 

 gination at its junction with the base of the spire. 

 Hab. Island of Margarita, West Indies. 



Species 160. (Mus. Stainforth.) 



Conus figulinus. Con. testa solidd, obesd, superrie ro- 

 tundatd ; cinereo-fuscd , f lis fastis numerosis circum- 

 liguti't ; spird planiusculo-convexd, apice mucronato ; 

 aperturd subampld, fauce pa/lide cmruleo-alhd . 



The clay Cone. Shell solid, stout, rounded at the up- 

 per part ; ashy brown, encircled with a number of 

 dark thread-like lines ; spire rather flatly convex, 

 apex pointed ; aperture rather large, interior pale 

 bluish white.

There is a pale ash-coloured variety of this well- 

 known species which should perhaps be noticed. 



Species 161. (Mus. Cuming.) 



Conus Nemocanus. Con. testd turbinatd, lutescente, in 

 medio a/bifasciatd, zonis f Usque tenuissimis undulatis 

 approximatis fu/vis tinctd, et strigis fulvis arcuatis 

 interdum longi/udinaliter pictd ; spird convexo-de- 

 pressd, subobtusd, fulvo tessellatd ; aperturce fauce 

 caruleo-purpured. 



The Nemoka Cone. Shell turbinated, yellowish, en- 

 circled with a white band in the middle, together 

 with a number of yellowish green zones, and very 

 fine undulated thread-like lines, sometimes painted 

 also longitudinally with dark broad curved streak? 

 of the same colour ; spire convexly depressed, ra- 

 ther obtuse, tessellated with yellowish green ; in- 

 terior of the aperture stained with bluish purple.

 ritius ; Capt. Smith. 



The longitudinal streaks which are so prominent in 

 the specimen here figured are very inconstant, and the 

 larger the shell is, the more indistinct they generally 

 appear. 



Species 162. (Mus. Wigan.) 



Conus abbas. Con. testd cylindraceo-turbinatd, subin- 

 flatd, aurantio-fusco subtilissimi reticulatd, zonis 

 duabus interruplis subindistincte tinctd ; spird con- 

 cavo-elatd, dpice mucronato ; aperturd latiusculd, 

 fauce alba. 



The abbot Cone. Shell cylindrically turbinated, ra- 

 ther inflated, very finely reticulated with orange- 

 brown, and indistinctly encircled with two inter- 

 rupted zones ; spire concavcly raised, apex pointed ; 

 aperture rather wide, interior white.
