Plate XXXIV. 



Species 187. (Fig. a and b, Mus. Stainforth.) 



Conus Guinaicus. Con. testd turbinatd, tenuiculd, sub- 

 inflatd, lavi, basim versus sulcata ; olivaceo-cinered, 

 maculis albido-caruleis nebulosis sparsis, interdum 

 subobsoletis, bifasciatim ornatd; spin! convexo-ob- 

 tusd, spiraliter striatd, suturis subsalebrosis ; aper- 

 ture fauce purpureo-fusco vivide tinctd. 



The Guinea Cone. Shell turbinated, rather thin, a 

 little inflated, smooth, grooved towards the base ; 

 olive-ash colour, ornamented with two bands of 

 scattered, clouded, sometimes obsolete, bluish white 

 spots ; spire convexly obtuse, spirally striated, su- 

 tures somewhat rugged or uneven ; interior of the 

 aperture vividly painted with purple-brown.

Variety /3. 



Testa aeruleo-albida, maculis rubido-fuscis sinualis vivide 



et peculiariter nebulosa. 

 Shell bluish white, vividly and peculiarly clouded with 



sinuated daik reddish brown spots.

 Hab. Coast of New Guinea; Hwass. 



The varieties of the Conus Guinaicus, as above noted, 

 the same mentioned by Lamarck, and figured in the 

 ' Encyclopedie Methodique,' exhibit such a remarkable 

 contr«st, both in colour and style of marking, that it 

 requires no ordinary degree of observation to mark their 

 complete specific relation in other respects. 



culatis ornatis, cinctd ; spird depresso-pland, auran- 

 tio-fusco maculatd ; apice mucronato. 



The butterfly-wing Cone. Shell turbinated, whitish, 

 encircled with three orange-brown zones, orna- 

 mented with a number of spots and articulated fillets 

 of darker brown ; apex pointed.

Hab. Mouth of the Gambia, Africa (found in clefts of 

 rocks) ; Lieut. Shaw. 



Lamarck particularizes four distinct varieties of this 

 species ; the pattern is however so exceedingly variable 

 in its exact detail, that it is impossible to establish a 

 scale of varieties with any degree of accuracy. 



Species 1S8. (Mus. Cuming.) 



Conus papilionaceus. Con. testd turbinatd, albidd, 

 zonis tribus aurantio-fuscis, maculis teeniisque arti- 



Species 189. (Fig. a, Mus. Stainforth; Fig. b, Mus. 

 Cuming; Fig. c, Mus. Dennison.) 



Conus episcopus. Con. testd turbinatd, solidd, nunc 

 eiongatd, nunc abbreviatd, obesd ; albidd aut rosaced, 

 fusco lutissinie reticulata, maculis perpaucis grandibus 

 interrupld, maculis albipunctatis ; spird convexd, apice 

 obtuso. 



The episcopal Cone. Shell turbinated, solid, some- 

 times elongated, sometimes short and stout ; white 

 or rose-tinted, very widely reticulated with dark 

 brown, interrupted with a few large brown blotches 

 dotted with white ; spire convex, apex obtuse. 



Lamarck, Anim. sans vert., vol. vii. p. 522. 



Hab. Ceylon, &c. 



Few species are more variable in form than the Conus 

 episcopus, some specimens being elongated and narrow, 

 whilst others are short and stoutly shouldered ; the 

 latter is however the more common growth, and cannot 

 well be confounded with its nearest allied species, the 

 Coni aulicus and magnificus.
