The Purpura Mures. Shell ovately oblong, attenuated 

 towards the base, rough ; seven- or eight-varicose,

 Murex miliaris, Gmebn. 

 Murex vitidinus, Lamarck. 



Hab. West Coast of Africa. 



The entu'e surface of this shell is peculiarly rough and 

 scabrous, and the varices are distinguished by their large 

 blunt roimded nodides.

The trilineated Murex. Shell abbreviately fusiform, 

 attenuated at both ends, rather soUd, transversely re- 

 gularly ridged ; longitudinally plicately ribbed ; thi-ee- 

 varicose, varices round, armed here and there with 

 very short scale-Kke spines ; wMte, encii'cled with 

 three distant chesnut-brown thi-ead-bke lines ; aper-

Reeve, Pro. Zool. Soc, 18-i5. 



Hab. Gulf of Mexico. 



A white shell, distinguished by three brown thread-like 

 cords crossing it at rather distant intervals. 



Species 104. (Mus. Metcalfe.) 

 Murex concinnus. Mur. testa elongato-clavaformi, longi- 



tudinaliter subohsolete plicato-costatd, transversim, exi- 

 mie liratd, lirarnm interstitiis minutissime squamatis ; 

 trivaricosd, varicibus spinosis, spinis breviusculis gra-

 fascis, quarum tribus saturatioribus, cingulatd; canali 

 gracili, longissimo, recto, s-uperne spinoso. 



The neat Murex. Shell elongately club-shaped, lon- 

 gitudinally rather obsolelely plicately ribbed, trans- 

 versely delicately ridged, interstices between the ridges 

 very minutely scaled ; three-varicose, varices spinous, 

 spines rather short, slender, erect, sharp ; pale light 

 brown, encircled with chesnut-browii thread-like lines, 

 thi-ee of which are of deeper colour than the remain- 

 der ; canal slender, very long, straight, spinous at the 

 upper part.

JIab. ? 



An extremely delicate and elegantly formed shell in w hich 

 the coloured thread-Kke lines, as in the preceding species, 

 of another form, are very characteristic. 



Species 105. (Mus. Cuming.) 



Murex rota. Mur. testd oblongo-ovatd, lavigald out ob- 

 solete scabrosd, spird brevi, cavernosd; septifariam vari- 

 cosd, varicibus quaternis quinisve ultimisfrondibus pla- 

 nk canaliculatis, ad apiceni dilatatis et peculiariter 

 palmatis, ornatis ; nived ; canali breviusculo. 



The water-wheel Murex. Shell oblong-ovate, smooth 

 or obsoletely scabrous, spu'e short, cavernous ; seven- 

 varicose, last foiu- or five varices ornamented with flat 

 eanabcidated fi'onds, dilated and peculiarly palmated 

 at the summit ; snowy white ; canal rather short. 



SowERBY, Conch. lUus. Cat. Murices, no. 73. f. 119, 



Hab. Molucca and Philippine Islands. 



It is strange that tlus well-known species shoidd not 

 have been distingidshed either by Lamarck or Deshayes. 

 It diS'ers from the Murex scorpio not only in having four 

 or five of the varices handsomely palmated, but is of a dif- 

 ferent fonn ; the body whorl Ijcing fuUer and not separated 

 from the penultimate whorl by so deej^ a suture ; the canal 

 moreover is shorter
