Species 11. (Mus. Cuming.) 



McREX EBINACEUS. Mitr. testd suhfusiformi-ovatd, spird 

 tnediocri; anfradibns mperm angulatis, inter varices 

 tubercidatis, transverdm fortiter costatis, costis rotun- 

 dato-tumidis, leviter imdatis, interditiis minutissime 

 squaniuloso-ruffosis, lird parvd squamulosd scepe iitter- 

 veniente ; quadrifariam ad septifariam varicosd, vari- 

 ciius valde irrer/tdariius, mine f random, ntmcfimbriato- 

 lamellatis ; alhido-fidvd ; canali lirevi, clanso, subre- 

 cnrvo. 



The hedge-hog Mukex. Shell somewhat fusiformly 

 ovate, spire midcUiug ; whorls angiilated at the upper 

 part, slightly tuberculated between the varices, trans- 

 versely strongly ribbed, ribs rotundately swollen, 

 slightly waved, interstices very minutely squamu- 

 lously rugose, with a small squamulous ridge running 

 thi'ough; fom-- or seven-varicose, varices very irre- 

 gular, sometimes frondose, sometimes fimbriately la- 

 meUated; white, stained with pale fulvous browii; 

 canal short, closed, a little recurved.

Variety p. 



Testa varicibus incrassatis, solidis ; costis transverm angus- 



tis, valde obscmioribus. 

 Shell with the varices thickened, solid ; transverse ribs 

 nan'ow, much more obscure.

 hayes' edit.), vol. ix. p. 598. Kiener, Iconographie

Vaiiety y. 

 Testa nunc varicosa, nunc evaricosa; anfractibus superne 



albicingulatis. 

 Shell sometimes varicose, sometimes without varices ; 

 whorls encu'cled with a white belt round the upper 

 part.

 hayes' edit.), vol. is. p. 597. Kieuer, Iconographie

 Hal). MediteiTanean, and coast of France and Britain, 

 (foimd at low water and at depths varying to four- 

 teen fathoms). 



Tills species, like the Murices trunculns and brandaris, 

 which inhabit the same sea, is extremely variable in gi-owth. 



some examples having as many as seven varices, whilst 

 others exhibit nothing more than a row of almost obsolete 

 plicated lamina;. In the variety /3, which Lamarck distin- 

 guished as the Murex Taretdinus, the lamina; of each varix, 

 instead of being raised like a festooned Ml, as in the type 

 of the species, are pressed down and, as it were, solidified 

 between the ribs ; whilst the ribs are narrower and more 

 obscm-e. The variety y is chiefly distinguished by a con- 

 spicuous wliite belt encircling the ribs at the angle, the 

 sculpture being in most respects like that of the variety /3. 

 This is much the scarcest state of the species ; it is very 

 well represented by M. Kiener as the Murex cingidiferus, 

 and I have a small but equally characteristic specimen from 

 the collection of Thomas Norris, Esq. 



Species 12. (Mus. WTiite.) 

 Murex eoliatus. Mur. testa ovato-oblongd, spird brem- 

 uscidd ; anfractlhus transversim ecstatic, costis parvis, 

 compressis, suldistantihis, interstitiis lavibns ; trifa- 

 riam varicosd, varicibus tenuibus, erecto-foliatis ; albidd, 

 castaneo-fusco fasciatd ; aperturd parvd, labro colu- 

 mellari simplici, externo dentictdato, derite unico planato 

 inferm armato ; canali brevi, plano-compresso, clanso. 

 The foliated Murex. Shell ovately oblong, spii-e ra- 

 ther short; whorls transversely ribbed, ribs small, 

 compressed, somewhat distant, interstices smooth ; 

 three-varicose, varices thin, erectly foliated ; whitish, 

 banded with chesnut brown; aperture small, colu- 

 mellar lip simple, outer lip denticulated, anned at the 

 lower part with a small flattened tooth ; canal short 

 flatly compressed, closed.

Purpura foliata, Mai-tyn, Univ. Conch, pi. 66. 

 Murex purpura alata, Chemnitz, Conch. Cab. vol. x. 

 p. 350. pi. 160. f. 1538-9. 

 Eab. Island of Sitka, north-west coast of America (foimd 

 in rocky places); Escholtz. 

 Lamarck committed a grand error in referring to Chem- 

 nitz's admii-able figure of this species for the illustration of 

 the Murex tripterus of Born ; and Kiener, confiding \vith 

 Ids usual fidelity in the purity of Lamarck's labours, has not 

 failed to repeat it. M. Deshayes has, however, published 

 the Murex foliatus in his recent edition of the ' Animaux 

 sans vertebres,' with an accurate citation of its synonymes, 

 and the species is no longer veiled with any obscurity.
