Patkandeau, Cat. Moll, de la Corse, pi. 7. f. 17, 18. 

 Murex crktatus, var., Philippi. 



Hab. Sicily. 



It is true that this species presents merely a modified 



growth of the Murex crisialiis, but that modification is of 



so marked a character that I have maintained Payrandeau's 



distinction. 



Species 111. (Mus. Cmning.) 

 Murex dipsacus. Jfur. testd fuMformi, spird angulato- 

 turritd, septifariam vel octofariam varicosd, varicibus 

 frondosis, frondibus squamitformibus, brevibus, nume- 

 rosis, varicum interstitiis, elevato-liratis, quasi cancel- 

 latis; albidd, fascia unicd fuscescente indistincte pictd ; 

 canali breviusculo. 



The teasle Murex. Shell fusiform, spire angidarly tur- 

 reted ; seven- or eight-varicose, varices frondose, 

 fronds scale-Uke, short, numerous, interstices between 

 the varices elevately ridged, as if cancellated ; whitish, 

 indistinctly painted with a single light brown band ; 

 canal rather short. 



Broderip, Pro. Zool. Soc, 1832. p. 194. 



Hab. St. Elena, West Columbia (from a rocky bottom at 

 the depth of twelve ftithoms) ; Cuming. 



A beautifully formed shell in which the sculptm-e is laid 

 in most symmetrical order. 



Species 112. (Mus. Cuming.) 



Murex cristatus. Mur. testd ohlongo-ovatd, tranwenim 

 liratd; aufractibus superne subdepresso-angulatis, sep- 

 tifariam varicosis, varicibus squamosis, squamis promi- 

 nentibus solidiusculk ; albicante, rosea aut rubente 

 tinctd; columelld basem versus leviter plicatd; labro 

 intus noduloso ; canali brevissitno. 



The crested Murex. Shell oblong-ovate, transversely 

 ridged; whorls somewhat depressly angidated at the 

 upper part, seven-varicose, varices squamate, scales 

 prominent, rather solid ; whitish, stained with pink

Brocchi, Conch. Foss., p. 394. pi. 7. f. 15. 



Rob. Sicdy. 



The main distinction between this species and the Murex 

 Blainvilii consists in the upper portion of the whorls being 

 more angidarly turreted, and the fronds much more pro- 

 minently developed. 



Species 113. (Mus. Cmning.) 



Murex lepidus. ifur. testd ohlongo-ovatd, transversim, 

 liratd, liris convexis, subirregularibus, conferti^ ; octo-

 confertis ; albidd, frondibus nigricantihus ; canali bre- 

 viusculo.

 short.
