Species 168. (Mus. Metcalfe.) 



Conus flavescens. Con. testd turbinatd, Uevi, basim 

 versus sulcata ; flavescente, maculis albis irregularibus 

 perpaucis biseriatim ornatd ; spird acuta, angulatd, 

 apice mucronato, elato. 



The pale yellow Cone. Shell turbinated, smooth, 

 grooved towards the base ; pale yellow, ornamented 

 with a very few irregular white spots ranged in 

 two rows ; spire sharp, angulated, apex pointed 

 and raised. 



Gray ?, Sowerby, Conch. Illus., f. 68. 



Hab. ? 



The spots which encircle this shell around the mid- 

 dle, and around the base of the spire, are exceedingly 

 irregular, having the appearance of spaces casually left 

 in the deposit of the pale yellow colour. 



Species 169. (Fig. a and b, Mus. Hankey.) 

 Conus bulbus. Con. testa subobeso-turbinatd , solidd, 

 supern'e rotundatd ; albd, fusco longitudinaliter stri- 

 gatd, strigis irregularibus, oblique undulatis, supern'e 

 et inferne diffusis ; spird brevi, apice mucronato. 

 The bulb-root Cone. Shell rather stoutly turbinated, 

 solid, rounded at the upper part ; white, longitu- 

 dinally streaked with brown, streaks irregular, ob- 

 liquely waved, spreading into each other at top and 

 bottom ; spire short, apex pointed. 



Variety (3. 

 Testa omnino fusca. 

 Shell entirely brown. 

 Reeve, Pro. Zool. Soc, 1843. 

 Hab. Cabenda, west coast of Africa (found at the depth 



of five fathoms in soft mud, washed down by the 



waters of the Congo) ; Hankey. 

 Four specimens of this very interesting species were 

 collected at the above-named locality by Lieut. Hankey. 

 It is a very solid shell, having the appearance of a small 

 bulb-root. 



Species 170. (Mus. Cuming.) 

 Conus APLUSTRE. Con. testd subobeso-turbinatd, trnui, 

 subinflatd, lavi, basim versus liratd ; rttbido-fusco et 

 camlet) pallid, et subirregulariter zonatd, tteniisfusco- 

 articulatis angustis numerosis subtilibus ornatd ; spird 

 depresso-convexd, apice mucronato. 



The little flag Cone. Shell rather stoutly turbinated, 

 thin, somewhat inflated, smooth, ridged towards the 

 base ; somewhat irregularly zoned with pale blue 

 and reddish brown, ornamented with a number of 

 fine narrow fillets articulated with brown; spire 

 depressly convex, apex pointed.

Hab. ? 



This is another new species, and will be recognised as 

 being very distinct from any hitherto described. 



Species 171. (Fig. a and b, Mus. Delessert.) 



Conus cancellatus. Con. testd fusiformi-turbinatd, 

 plus minusve obeso-inflatd, basim versus attenuatd ,■ 

 transversim sulcata, sulcis striis profundis longitu- 

 dinalibus decussatim cancellatd ; albd, maculis sub- 

 quadrangularibus fuscescenlibas trifasciatim cinctd, 

 fascid infimd subobsoletd; spird exsertd, acuminata, 

 spiraliter striatd, marginibus apicem versus subtilis- 

 sime nodulosis ; labro eximie crenulalo. 



The cancellated Cone. Shell fusiformly turbinated, 

 more or less stoutly inflated, attenuated towards 

 the base; transversely grooved, grooves decussately 

 cancellated with deep longitudinal striae ; white, en- 

 circled with three indistinct bands of nearly qua- 

 drangular spots of pale brown, the lowest of which 

 is nearly obsolete ; spire exserted, acuminated, 

 spirally striated, edires minutely noduled towards 

 the apex ; lip delicately crenulated.

 pi. 3. f. 1. 

 Conus pagodus, Chenu. 



Hab. Island of Taheite, Pacific Ocean ; Lamarck. 



This highly interesting species was only known to 

 Lamarck in bad condition, the specimen described by 

 him, which I have fortunately had an opportunity of 

 examining, being much worn and quite destitute of co- 

 lour. It varies considerably in obesity of form, and the 

 narrower varieties are generally the fainter coloured. 



The Conns cancellatus is not uncommon in English 

 collections ; but the magnificent example here figured, 

 from the collection of M. Delessert of Paris, is superior 

 to any that I am acquainted with.
