CONUS.— Plate XIII. 



basin versus sulcatd ; spird rohmdatd, convexiusculd, 

 fusco vividi maculatd, apice mucronato ; citrind, ma- 

 cules punctisque fuscis varPe cinctd. 



The butter-firkin Cone. Shell stoutly turbinated, 

 solid, grooved towards the base ; spire rounded, 

 rather convex, vividly spotted with brown, apex 

 pointed ; citron-coloured, variously encircled with 

 brown dots and spots.

Hab. Ceylon, &c. 



Lamarck enumerates six varieties of this well-known 

 species, differing more or less in the number, shape and 

 arrangement of the dots and spots. 



Species 68. (Mus. Cuming.) 



Conus tornatus. Con. testa elongato-turbinatd, subfu- 

 si/ormi, leviter sulcatd ; spird valdeelatd, turrito-acu- 

 minatd, apice acuto; albd,fusco-nigricante bifasciatim 

 nebulosd, punctis fuscis irregularibus ubique cinctd. 



The turned Cone. Shell elongately turbinated, rather 

 fusiform, slightly grooved ; spire very elevated, tur- 

 rited, apex sharp; white, clouded with blackish 

 brown so as to form two faint bands, and every- 

 where encircled with rows of dark irregular dots.

Sowerby, Conch. Illus., f. 25. 



Hab. Xipixapi, Central America (found in sandy mud at 

 the depth of from ten to twelve fathoms) ; Cuming. 



The Conus interruptus, from which this species may be 

 readily distinguished by the turrited elevation of the 

 spire, is perhaps the nearest allied to it. 



Species 69. (Mus. Adamson.) 



Conus furvus. Con. testd elongato-turbinatd, angustd, 

 Itevi, spird elatd ; luteold, fasciis duabus, latis, furvo- 

 fuscis, cingulatd; aperturd lineuri. 



The dusky Cone. Shell elongately turbinated, narrow, 

 smooth, spire elevated; yellowish, encircled with 

 two broad, dusky browTi bands ; aperture linear. 



Reeve, Pro. Zool. Soc, 1843. 

 Hab. Islands of Ticao and Masbate, Philippines (found 

 in sandy mud at low water) ; Cuming. 



I kindly thank Mr. Adamson for sending me this new 

 and interesting Cone, a few specimens of which have 

 been collected by Mr. Cuming. 





Species 70. (Mus. Dennison.) 



Conus pyriformis. Con. testd symmetric^ pyriformi, 

 transversim subtilissime striata, basin versus leviter 

 sulcatd; anfractibus superne rotundatis, spird con- 

 vexiusculd, spiraliter sulcatd, apice elato, basi paulu- 

 lum recurvd ; albidd, cameo eximie tinctd. 



The pear-shaped Cone. Shell symmetrically pyriform, 

 transversely very finely striated, slightly grooved 

 towards the base ; whorls rounded superiorly, spire 

 gently convex, spirally grooved, apex raised, base a 

 little recurved ; whitish, delicately tinged with flesh- 

 colour. 



Hab. Bays of Caraccas and Montija, West Columbia 

 (dredged from sandy mud at the depth of from seven 

 to ten fathoms) ; Cuming. 



This shell attains a much larger size than that of the 

 specimen, which I have here selected on account of the 

 extreme delicacy of its colour. 



Species 71. (Mus. Stainforth.) 



Conus artoptus. Con. testd cylindraced, angustd, trans- 

 versim granoso-striatd ; spird convexd, rotundatd ; 

 albidd, aurantio-fusco trifasciatim nebulosd, intersti- 

 tiis punctatis ; aperturd lineari. 



The baked Cone. Shell cylindrical, narrow, trans- 

 versely granulously striated ; spire convex, rounded; 

 whitish, banded in three places with clouded spots 

 of orange-brown, the interstices being dotted with 

 the same colour ; aperture linear. 



Sowerby, Conch. Illus., f. 35. 



Hab. ? 



There can be no doubt of the specific importance of 

 this shell; in form it bears some resemblance to the 

 Conus clavus, but it differs materially in all other respects 

 from any species of the genus.
