The HOLLOWED Murex. Shell pyramidally oblong, trans- 

 versely ribljed, ribs naiTow, peculiarly elevated, very 

 minutely noduled along each side, reticulated with 

 the varices, interstices hoUowed ; fom'- to eight-vari-

KlENER, Iconograpliie coq. w., p. 2-i. pi. 46. f. 2. 



Hab. Panama (foimd under stones at low water) ; Cuming. 



A pretty deeply reticulated species, partaking somewhat 

 of the characters of Triton. 



Species 158. (Mus. Gruner, Bremen.) 



Murex Pukpukoides. Mm-, testd ovatd, subventricosd, 

 spird brevi; anfractihis svperne subangulatis, costis 

 pamis angustis longiludinaUbus el transversis infra 

 unguium reticidalis, costis transversis cotifertioribus ; 

 albicante, fascia fuscescenle interdum cingulatd ; aper- 

 turd ampld, patuld. 



The Purpura-like Mdkex. Shell ovate, rather ventri- 

 cose, sjjire short; whorls slightly angulated at the 

 upper part, reticulated below the angle with small 

 narrow transverse and longitudinal ribs of which the 

 transverse are the closer together ; whitish, sometimes 

 encircled with a pale brown band ; apertui'C large, 

 wide open. 



DnNKER, MSS. (Cassel). 



Hab. Cape of Good Hope. 



A small open-mouth shell, with no regidar indication of 

 varices. 



Species 159. (Mus. Cuming.) 



Murex badius. Mur. testd obeso-fusiformi, solidiusculd, 

 trausversita elevato-striald, slriis compicuis, regulari- 

 bus ; septifariam varicosd, varicibus iucrassatis, sitb- 

 rotmidis ; rubido-castaned ; canali paululum recnrvo. 



The brown Murex. Shell ovately fusiform, rather solid, 

 transversely elevately striated, stri;e conspicuous, re- 

 gular ; seven-varicose, varices tliickened, somewhat 

 round ; reddish chesnut ; canal a little recmwed. 



Reeve, Pro. Zool. Soc, IS-IS. 



Hab. ? 



A solid dark brown shell, certainly distinct fi-om any 

 species that I have seen. 



Species 160. (Mus. Cuming.) 



Murex erosus. Mur. lestd fyramidali-oblongd, tra/isrer- 

 sim liratd, liris angustis, confertis,2ilaniuscuUs, utrinque 

 crenalis, inlerstiliis profund'is ; basi cavernoso-sulcatd, 

 sulco septis duobus decussalo ; irregulariler varicosd, 

 anfraclu ultimo varicibus duobus fortib us, ccsteris obso- 

 lete varicosis ; caruleo-nigricante, varicibus albican- 

 tibus ; aperturd minntd ; canali brevi. 



The eroded Murex. Shell pyi-amidaUy oblong, trans- 

 versely ridged, ridges narrow, close-set, rather flat- 

 tened, crenated on both sides, interstices deep ; ca- 

 vernously grooved at the base, groove crossed by two 

 septa ; uTegularly varicose, two strong varices upon 

 the last whorl, the rest obsoletely vaiicose ; blueish 

 black, varices white ; aperture veiy small, canal short. 



Broderip, Pro. Zool. Soc, 1S33. 



Hoi. Panama (found under stones) ; Cimiing. 



This is rather a questionable species oi Murex, partaking 

 so much as it does of the characters of Triton. It differs 

 in its scidptiu-e throughout fi-om the Murex alwatus, but 

 especially in being encircled with a deep broad cavernous 

 sroove at the base. 



Species 161. (Mus. Cuming.) 



Murex distinctus. Mur. tesld fusiformi-lurriculatd, 

 transversim striatd aut exiliter liratd, spir/e suturis 

 subprofundis ; anfractibus rotundatis, sexfariam vari- 

 cosis, varicibus incrassatis, noduliferis ; albidd aid fla- 

 vescente ,- aperturd parvd, rotundd ; canali brevi, siib- 

 ascendente. 



The divided Murex. Shell fusiformly turriculated, 

 transversely striated or faintly ridged, sutures of the 

 spke rather deep ; whorls rounded, six-vaiicose, va-
