Species 106. (Mus. Cuming.) 



MuREX SCORPIO. Miir. testa elongato-ovatd, gracili, sub- 

 fusiformi, spird hrevi, suturis profundis et latis ; qtdn- 

 quefarimn varicosd ; varice ultimo frondibus plants ca- 

 naliculatis, ad apiceni dilatalis et peculiariter palmatis, 

 ornato ; nigricaute-fuscd, interdmn alba; aperturd

The scorpion Murex. Shell elongately ovate, slender, 

 somewhat fusiform, spu-e short, sutm-es very deep 

 and broad ; five-varicose, last whorl ornamented with 

 flat canaliculated fronds, dilated and peculiarly pal-

It cannot be denied that a veiy close affinity exists be- 

 tween this and the preceding species ; but it may be as- 

 serted without hesitation, that the differences are positive 

 and constant. lu addition to those akeady eniunerated, 

 it may be observed, that the varices ai-e always fewer in 

 number, and the last two or three are entirely separated 

 from the penultimate whorl by the deep wide sutm-e. 



Species 107. (Mus. Cuming.) 



MuRE.x NODATUS. Mur. testd obbrevtato-fiisiformi, subcla/va- 

 td, utrinque attenuatd, loxrjitudinaliter subpUcatd, trans- 

 versim liratd, liris nodiferk ; tri/ariam varicosd, vari- 

 cibus rotundis, spinis brevibus acutis armatis ; luteo- 

 fuscescente, litieis fiiscis inter nodos cingulatd ; canali 

 longiusculo, gracili, oblique a.scendente. 



The knotted Murex. Shell abbreviately fusiform, clavate, 

 attenuated at both ends, longitudinally subplicated, 

 transversely ridged, ridges uodiferous ; three-varicose, 



varices round, anned with shai-p small spines ; yel- 

 lowish-brown, encu'cled between the nodules with 

 brown lines ; canal rather long, obliquely ascending.

Hab. ? 



This shell was iigm-ed in the Conchological Illustrations 



by Mr. Sowerby, as a variety of the Murex motacilln, with 



which species he was probably not at the time acquainted, 



as it beai's little or no affinity with it. 



Species 108. (Mus. Saul.) 



Murex similis. Mur. testa abbreviato-fasiformi, spird 

 subturrild,anfractibus superne subaiigulatis, transversim 

 obsolete striatis, tuberculis tribus nodiferis inter varices; 

 trifariam varicosd, varicibus spinis brevissimis acutis 

 armatis; luteo-albicante, fasciis duabiis auratitio-fus- 

 cescentibus latiusculis distantibus cingulatd ; aperturd 

 rotundato-ovatd, labro columellari subconspicuo ; canali 

 longiusculo, oblique asceiidente. 



The similar Murex. Shell abbreviately fusiform, spire 

 somewhat tiuTcted, whorls a little angulated at the 

 upper part, transversely obsoletely striated, with three 

 uodiferous tubercles between the varices ; tlu'ee-vari- 

 cose, varices anned mth very short sharp spines ; 

 yellowish white, encircled with two rather wide orange- 

 brown bands ; apertm-e rotundately ovate, columeUar 

 Mp rather conspicuous ; canal rather long, obliquely 

 ascending.

Hab. ? 



This is a vei-y excellent species, and perfectly distinct 



from the preceding, a comparison with which is recorded 



by Mr. Sowerby in the Pro. Zool. Soc, 1840, p. 140, 



under the impression of its being the Murex motacilla.
