CONUS.— Plate IV. 



Species 19. (Mus. Stainforth.) 



Conus australis. Con. testd elongatd, cylindraceo-tur- 

 binatd, transversim liratd, liris nunc lavibus, nunc 

 granosis ; albidd, maculis grand/bus scepissime, bizo- 

 natd, minoribus linearibus ubique venosd ; spird ele- 

 vatd, acuta. 



The southern Cone. Shell rather long, cylindrically 

 turbinated, transversely ridged, ridges sometimes 

 smooth, sometimes granular, generally doubly band- 

 ed with large chestnut spots and veined over the 

 entire surface with smaller linear ones ; spire ele- 

 vated and acute.

Hab. Swan River. 



The specimen selected for illustration is small and per- 

 fectly smooth ; the granular variety is scarcely of suffi- 

 cient importance to require especial notice. 



Species 20. (Mus. Stainforth.) 



Conus lithoglyphus. Con. testd turbinatd, versus basin 

 granulatd, rubro-fuscd, in/erne nigricante, maculis 

 conspicuis niveis superne et mediane fasciatd ; spird 

 mediocri, subobtusd. 



The pebble-carved Cone. Shell turbinated, granu- 

 lated towards the base, reddish brown, blackish at 

 the basal extremity, banded round the middle and 

 upper parts with clear snowy white spots; spire 

 ordinary, rather obtuse.

Hab. Island of Ticao, Philippines, &c. 



The two bands of snowy white spots whicli encircle 

 the middle and upper portion of this shell make it espe- 

 cially easy to distinguish. 



Species 21. (Mus. Stainforth.) 



Conus centurio. Con. testd dilatato-turbinatd, versus 

 basin sulcata ; albd, fasciis tribus aurantiis cingu- 

 latd, interstitiis lineis, oblique et vivide undatis, ve- 

 nustissime pictis; spird concavo-convexd, anfractuum 

 angulis supernis fusco-maculatis ; apice obtuso. 



The centurion Cone. Shell dilately turbinated, sul- 



cated towards the base ; white, encircled with three 

 orange bands having the interstices elegantly 

 painted with strong oblique zigzag lines ; spire 

 concavely convex, brown-spotted round the upper 

 angle of the whorls ; apex obtuse.

This shell is not unlike some varieties of the Conus 

 Malaccanus ; they are, however, well distinguished from 

 each other, the former being the more dilated, and well 

 characterized by the zigzag lines. 



Species 22. (Mus. Stainforth.) 



Conus Adamsoni. Con. testd cylindraceo-conicd, ventrico- 

 siusculd, superne attenuatd, nitente quasi porcellaned, 

 albd, sonis tribus roseo-nebu/osis cingulatd, interstitiis 

 punctiunculis triquetris, diagonaliter dispositis, ele- 

 gantius ornatd ; (infractions supra infraque sulcatis ; 

 spird depresso-pland. sulcata' et striatd. 



Adamson's Cone. Shell cylindrically conical, rather 

 ventricose, attenuated at the upper part, shinin°- 

 as if it were porcelain ; white, encircled with three 

 clouded rose-tinted zones, the spaces between them 

 being elegantly filled up with small three-cornered 

 dots ranged in diagonal order; upper and lower 

 parts of the whorls sulcated ; spire flatly depressed, 

 grooved and striated. 



Gray, MSS. British Museum. 



Conus cingulatus, Sowerby, Tankerville Catalogue, 

 Appendix, p. xxxiv. and Conch. Illus., f. 10S. 



Hab. Australia. 



This beautiful rose-tinted porcelain shell appears to 

 have been first introduced by Sowerby ; I am forced, 

 however, to adopt the manuscript title subsequently 

 attached to it by Gray, because the name first proposed 

 had been already used by Lamarck in reference to another 

 species. Care must however be taken not to confound 

 Gray's Conus Adamsoni, named after a distinguished ama- 

 teur conchologist of Newcastle, with Lamarck's Conus 

 Adansoni, dedicated to the memory of the celebrated 

 malacologist of Senegal.
