Supp. Plate V. 



Species 246. (Mus. Dennison.) 



Conus lemniscatus. Con. testa subangulato-conicd, 

 medio leviter contractu, basin versus attenuatd, undique 

 subtiliter liratd ; spird acuminata, increment 'i lineis 

 arcuatis undique notatd, apice acuta ; albidd, fusces- 

 cente-aurantio, longitudinaliter undulatd, litis trans- 

 versis attends fusco-aurantio subtilissime articulatis. 



The silken-stringed Cone. Shell somewhat angularly 

 conic, slightly contracted towards the middle, atten- 

 uated towards the base, delicately ridged throughout ; 

 spire acuminated, marked throughout with carved 

 lines of growth, apex sharp ; whitish, longitudinally 

 waved with brown-orange, every alternate transverse 

 ridge very finely articulated with the same colour. 



Hali. ? 



This very interesting species was found amongst the 

 shells collected by Sir Edward Belcher during the voyage 

 of the Sulphur, without any information as to its locality. 



Species 247. (Mus. Cuming.) 



Conus stillatus. Con. testa oblougd, injlatd, tramwrsim 

 striata, basin versus crebrkulcatd, spird depressiusculd, 

 regular iter striato-sulcatd ; lacted, superne maculis 

 ustulato-fuscis in lineis descendentibus, maculis salu- 

 ratioribus ad basin picld. 



The trickled Cone. Shell oblong, inflated, transversely 

 striated, closely grooved towards the base, spire 

 rather depressed, regularly striately grooved ; cream- 

 white, painted at the upper part with burnt-brown 

 spots, descending in lines, with darker brown spots 

 at the base. 



Hob. Moluccas. 



Distinguished from C. spectrum slightly in form, but 

 more particularly by the character of its markings, the 

 colour of which is a darker brown. 



Species 248. (Mus. Cuming.) 



Cones emaciatus. Con. testa pgraiuidali-couicd, eras- 

 siusculd, solidd, medio contractd, basin versus attenuatd, 

 liris angnstis undique fitalimfuniculatd, spird depressd, 

 laevigata; albidd, vet luted, liris saturalioribus, basi 

 intense creruleo-violaced. 



TnE emaciated Cone. Shell pyramidally conic, rather 

 thick, solid, contracted in the middle, attenuated 



June 



towards the base, corded throughout with narrow 

 thread-like ridges, spire depressed ; smooth, whitish 

 or yellowish, ridges rather darker, base deep blue- 

 violet. 

 Ilab. Philippine Islands ; Cuming. 



Closely allied to C. virgo, but distinguished in a very 

 characteristic manner by its contracted attenuated growth, 

 and by the thread-like cords with which it is encircled. 

 M. Gubba of Havre also possesses specimens. 



Species 249. (Mus. Cuming.) 



Conus Lorenzianus. Con. testa obeso-conicd, orassd, 



ponderosd, lavigald, spird elevatiusculd, lavigafd ; 



alba, Jlammis maculisque rufo-castaneis usque ad basin 



fascialim picld. 

 Lorenz's Cone. Shell stoutly conical, thick, ponderous, 



smooth, spire rather elevated, smooth ; white, painted 



down to the base with flames and spots, disposed in 



bands. 

 Chemnitz, Couch. Cab. vol. ii. p. 51. pi. 181. f. 1754-8. 



Conus Jlammeus, Lamarck. 

 Hub. Honduras ; Dyson. 



Por want of a sufficient regard to Chemnitz' character of 

 this species, " basi punctis rubicuudis punctata," I referred 

 the C. Lorenzianus at PL 27, to a shell in the collection of 

 M. Delessert having that name attached to it and bearing 

 some general resemblance to the figure of the Conchylien 

 Cabinet. This shell proves to be identical with the 

 species figured at PL 16, as C. zebra, now distinguished as 

 C. virgalus, and will be found to differ particularly from 

 C. Lorenzianus in the character above recited, never being 

 spotted or dotted at the base. Chemnitz' figure will be 

 found to agree in this respect with the C. Jlammeus of 

 Lamarck, as he himself truly indicated, with the aid of the 

 figure in the Encyclopedie Methodique (PL 336. f. 1) and 

 of M. Kiener (PL 23. f. 1), and by an easy transition with 

 the figure in the accompanying plate, which represents a 

 stout peculiarly marked state of the species collected by 

 Mr. Dyson at Honduras. 



Species 250. (Mus. Cuming.)

 basi subrude contortd, transversim obsolete undulato-stri- 

 atd, longitudinaliter lineis incrementi irregulariter
