The prince Mubex. Shell somewhat pyriformly ovate, 

 six-angled, spii'e short ; whorls angulated at the upper 

 part, transversely somewhat obsoletely ridged and 

 striated; six-varicose, varices froudose, fronds some- 

 what rude, erect ; white, stained with transverse rusty 

 brown lines and bands ; canal short.

Hab. Puerto Portrero, Central America (found on coral 

 reefs at low water) ; Cuming. 



The fronds of this species are of a peculiarly rude erect 

 character, and that upon the angle is in each varix much 

 stouter at the base than any of the rest. The style of co- 

 loiu'ing, which is of a reddish rusty brown, reminds one of 

 the Murex radix though quite unlike. 



Species 24. (Mus. Cuming.) 



Murex megacerus. Mur. testd fusiformi-ovatd, quad- 

 rmigulari, splrd subacuminatd ; anfractibus supenie 

 leviter angulatis, inter varices nodoso-plicaiis, trans-

 peculiariter erectis, ad apicem leviter foliotis, fronde 

 stiperd longissimd; fulvo-albicante, ferriigiueo-fusco

The large-horned Murex. Shell fusiformly ovate, 

 foui'-angled, spii-e somewhat acuminated ; whorls 

 slightly angulated at the upper part, nodosely plicated 

 between the varices, transversely ridged and striated, 

 ridges small, sharp-angled ; fom"-varicose, varices 

 fi'ondose, fronds peeidiarly erect, slightly foliated at 

 the top, uppennost frond the longest ; fulvous white, 

 stained more or less with rusty brown ; canal slightly 

 elongated. 



SoWEBBY, Pro. Zool. Soc, ISiS. 



Hah. West Indies. 



This species, though presenting no peculiarity of colom-, 

 may be readily distinguished by its four-varicose and quad- 



rangular structiu'e, and by the straight erect character of 

 the fronds. 



Species 25. (Mus. Cuming.) _ _ -•-'--•-' 

 Murex Sinensis. Mnr. testd elongato-ovatd, subfwsi- 

 fornii, tenni, spirce suturis stibimpressis ; anfractibus

 The Chinese Murex. Shell elongately ovate, somewhat 

 fusiform, thin, sutures of the spire rather impressed ; 

 whorls transversely ridged and striated, nodiferous 

 between the varices ; three-varicose, varices frondose, 

 fronds I'egidar, cm'ved, beautifidly flowered, deeply 

 seiTated ; whitish, stained with brown, transverse 

 lines brown ; lip strongly erectly toothed beneath the 

 middle. 

 Reeve, Pro. Zool. Soc, 1845. 



Murex elongatus, var., Sowerby, Conch. lUus. f. 88. 

 Hab. China. 



The species which I here distinguish by the new title 

 of Murex Sinensis appears to have been confounded for some 

 time past with the Murex elongatus, or the young of the 

 Murex inflatus. It is uniformly of a thin sti-ucture, and the 

 fronds are of a delicate open flowery gi-owth. 



Species 26. (Mus. Cimiing.) 



Murex elongatus. Mur. testd fusiformi-elongatd, tenui- 

 culd, subventricosd ; anfractibm transversim elevato- 

 striatis, inter varices tnberculatis ; trifariam varicosd, 

 varicibus frondosis, frondibus curvatis, hiciso-serratis ; 

 rubido-fuscd, colmnelld et apertura fauce nigricante- 

 violascentibus ; canali subelongato. 



The elongated Murex. Shell fusiformly elongated, ra- 

 ther thin, somewhat ventricose ; whorls transversely 

 elevately striated, tuberculated between the varices ; 

 three-varicose, varices fi-ondose, fronds curved, deeply 

 serrated ; dark reddish brown ; columeOa and interior 

 of the aperture blackish violet ; canal rather elongated. 



Lamarck, Anim.sans vert. (Deshayes'edit.),vol.ix. p. 571. 



Hab. Gulf of Mexico. 



There is not so much novelty in the elongated structure 



of this species as in its uniform dark reddish-brown colour, 



and the blackish-violet enamel of the aperture.
