MUREX.

Species 97. (Fig. 87, H.M. The King of Denmark.) 



MuEES TKIGONTJLUS. Mur. testd trujono-fusifonii, cur- 

 vatd^ transversim nodoso-Uratd, ad basem sfriatd et cos- 

 tatd, lo»gituduialiter plicatd ; trifariam varicosd,vm-i-

 mbelongato-recurvo ; lutescente-aUa, rosea tindd et ne- 

 bidosd, macidarum quadratarum fuscescentium seriebus 

 duabui ornatd. 



The teiangular Murex. Shell triangularly fusiform, 

 curved, transversely nodosely ridged, striated and 

 ribbed at the base, longitudiuaUy plicated ; three-va- 

 ricose, varices tuberculiferous, pMcately laminated at 

 the base ; canal somewhat elongately reciu'ved ; yel- 

 lowish wliite, stained and clouded with pink, orna- 

 mented with two rows of square pale browTi spots.

Eah. Eed Sea. 



This important shell, from the private collection of 

 H.M. The King of Deumai-k at Copenhagen, is the only 

 example of the species that I have seen with the canal 

 properly developed. Those figured by Sowerby, Kiener, 

 and in the ' Encyclopedie Methodique,' being worn spe- 

 cimens, and all having the delicate recurved canal posi- 

 tively broken off. It may be recognised by the character- 

 istic plicated lamina into which the varices terminate at 

 the base, and by its strong scarlet-pink coloming. 



It may be as well to repeat that the Miirices triqueter 

 and trigomdus are figured in the ' Encyclopedie Methodique' 

 and by Kiener, the one for the other. 



Species 88. (Mus. Cuming.) 



MuEEX MOTACILLA. Mur. testd clavaformi, crassimculd, 

 transversim Uratd, Urh angitstis, subnodosis, tuberculis 

 prominentibus inter varices ; trifariam varicosd, vari- 

 cibus rotundis, spina brevi acuta aittice armatd, postice 

 lamhmtd et spinoso-squamatd ; canali attmuato, late- 

 raliter reciirvo ; albicante, macidis fasciisque rufo-fuscis 

 profuse tinctd. 



The wagtail Murex. Shell club-shaped, rather thick, 

 transversely ridged, ridges naiTow, slightly nodose, 

 with two prominent tubercles between the varices ; 

 three-varicose, varices round, anned anteriorly with a 

 sharp short spine, posteriorly laminated and spinosely 

 scaled ; canal attenuated, laterally reciu-ved ; whitish. 



profusely stained with reddish brown bands and 

 blotches. 

 Chemnitz, Conch. Cab., vol. x. pi. 163. f 1563. 



Murex motacilla, var. b, Lamarck. 

 Bab. Senegal. 



The shell which Lamarck describes for the Murex mota- 

 cilla of Chemnitz, is one of very opposite character, now 

 known to conchologists as the Murex elegant ; his var. b. 

 is the tme species. 



Mi\ Sowerby described the Murex elegam in the ' Pro- 

 ceedings of the Zoological Society' for 1840, and figured 

 it in his ' Conchological Illustrations,' f. 8-t, without dis- 

 covering it to be Lamarck's Murex motacilla. He more- 

 over published a dra-ning of another shell at Kg. 69, as a 

 variety of Murex motacilla, which has Uttle or no affinity 

 with it, and which I propose to distinguish by the new 

 title of Murex articidatus. 



M. Kiener very properly distinguishes, and correctly 

 figiu'es, the Murices elegans and motacilla, confounded to- 

 gether by Lamarck ; but ludicrously applies to his M. mo- 

 tacilla the description which Lamarck drew up from the 

 now called M. elegans. 



Species 89. (Mus. Brit.) 

 Murex scolopax. Mtir. testd elongato-clavceformi, lad, 

 ant transversim obsolete striata et liratd, liris distan- 

 tibus ; trifariam varicosd, varicibns spinosis, spinis so- 

 lidiusculis, subdistantibus, sursum inclinatis ; canali 

 sexfariam spinoso, seriebus alternis spinis fortibus lon- 

 gissimis, Itorizontalibus, alternis spinis minutis erectis ; 

 albicante, liris tran.sversis conspicue anrantio-fuscis. 

 The woodcock Murex. Shell elongately club-shaped, 

 smooth or transversely obsoletely striated and ridged, 

 ridges distant ; three-varicose, varices spinous, spines 

 rather soUd, somewhat distant, bent upwards ; canal 

 armed with six rows of spines, one row with the spines 

 strong, very long, and horizontal, alternating with 

 the other, having the spines minute and erect ; wliitish, 

 transverse ridges conspicuously colomed with orange- 

 broivn.

Murex, no. 3. 

 Hah. Persian Gulf. 



This species may be distinguished, amongst other cha- 

 racters, by the narrow transverse orange-brown bands.
