CONU S. 



Plate XLV 



Species 246. (Mus. Gray.) 



Conus trochulus. Con. testd abbreviato-turbinatd, 

 obesd, solidd, Itevigatd, basim versus sulcata; albd, 

 aperture fauce rubido-violaceo tinctd ; spird obtuso- 

 coiwexd, Itevigatd. 



The little top Cone. Shell shortly turbinated, stout, 

 solid, smooth, grooved towards the base ; white, 

 interior of the aperture stained with reddish violet ; 

 spire obtusely convex, smooth. 



Reeve, Pro. Zool. Soc, 1843. 



Hab. ? 



This species, of which there are several examples in 

 the British Museum, all with the violet-tinged aperture, 

 exhibits the same contrast of colour as a very peculiar 

 white variety of the Conus nivosus. 



Species 247. (Mus. Stainforth.) 



Conus sugillatus. Con. testd turbinatd, solidiusculd, 

 Itevigatd, basim versus subobsolete noduloso-liratd ; 

 albidd,fasciis duabus latissimis livido-olivaceis, lineis- 

 que exilibus fuscescente-punctatis, cinctd ; spird pla- 

 no-convexd, canaliculatd, apice mucronato, elato, an- 

 fractuum marginibus subtilissime oblique nodulosis ; 

 basi et aperturte fauce violaceo tinctd. 



The bruised Cone. Shell turbinated, rather solid, 

 smooth, somewhat obsoletely nodulously ridged 

 towards the base ; whitish, encircled with two very 

 broad, livid olive bands, and a number of faint brown- 

 dotted lines; spire flatly convex, canaliculated, apex 

 raised, pointed, edges of the whorls very finely 

 obliquely noduled ; base and interior of the aper- 

 ture stained with violet. 



Reeve, Pro. Zool. Soc., 1843. 



Hab. ? 



This shell may probably have been confounded with 

 the Conus lividus ; it is, however, quite distinct from that 

 species both in the detail of the painting and in the 

 structure of the spire. The spire is canaliculated, and 

 very peculiarly beaded with fine oblique nodules, the 

 canaliculated surface being of an olive-brown colour, 

 whilst the nodules are white. 



Species 248. (Mus. Stainforth.) 



Conus strigatus. Con. testd elongato-turbinatd, subcy- 

 lindraced; albidd, stricjis cinnamomeo-fuscis,confertis. 

 interruptis, undique cinctd, maculisque oblongis pallide 

 variegatd ; spird convexo-elatd. 



The striped Cone. Shell elongately turbinated, some- 

 what cylindrical, whitish, encircled throughout with 

 anumber of interrupted, close-set, cinnamon-brown 

 stripes, and palely variegated with oblong blotches 

 of the same colour ; spire convexly raised.

Lamarck, Anim. sans vert., vol. vii. p. 516. 



Hab. ? 



This is a species of rather doubtful character, and I 

 am not sure that the specimen here figured from the 

 collection of the Rev. Mr. Stainforth is really the shell 

 intended. I venture to publish it as such because it 

 agrees, as far as its condition allows, with the minute 

 description of the Conus strigatus given by Bruguiere in 

 the ' Encyclopedie Methodique' ; and it appears more- 

 over perfectly distinct from any other species of the 

 genus. 



Species 249. (Fig. a, Mus. Gray ; Fig. b, Mus. Stain- 

 forth ; Fig. c, Mus. Brit.) 



Conus mutabilis. Con. testd turbinatd, subpuriformi, 

 Itevigatd, basim versus undulatim sulcatd; f'uscescente, 

 in medio stepe pallidissimd, fusco irregulariter vir- 

 gatd, lineisque fuscis interruptis cinctd ; spird con- 

 vexd, spiraliter striata, suturis rudibus, apice elato. 



Tne changeable Cone. Shell turbinated, somewhat 

 pear-shaped, smooth, grooved in a waved manner 

 towards the base ; light brown, often very pale in 

 the middle, irregularly streaked with brown, and 

 encircled with interrupted brown lines ; spire con- 

 vex, spirally striated, sutures rugged and uneven, 

 apex raised.

 and 1 7.59. 



Hab. ? 



In my observations on the Conus vexillum (Plate I. 

 Species 3.), it is related how Lamarck quotes as a va- 

 riety of that species a shell figured by Chemnitz under 

 the title of Conus mutabilis. These remarks were offered 



February 1844.
