MuREX AXicoRNis. Variety ^. For description of this 

 species, see Plate XV. 



Species 38. (Mus. Cuming.) 



MuREX Banksii. Mur. testa suielongato-fmifomii, tram- 

 versim granoso-liratd et striata, inter varices trituber- 

 calata ; trifariam varicosd, varicihus froudosis, frondi- 

 bus lacbiiato-foleaceis, recurvis^fronde mhiutd bau hi- 

 tefveniente ; castaneo-fmcescente, froudibus nigricante- 

 fuscis, apice rosacea ; aperturd rotundatd, labro pul- 

 cJwrrimi denticulato ; canali Imigimcido. 



Banks' Ml'rex. Shell somewhat elongately fusiform, 

 transversely granosely ridged and striated, with three 

 tubercles between the varices ; three-varicose, varices 

 frondose, fronds laciiiiately foliaceous, recurved, with 

 a minute frond intervening at the base ; light chesnut 

 brown, fronds blackish brown, apex pink ; aperture 

 rounded, lip very beautifidly denticulated ; canal ra- 

 ther long. 



SowERBY, Pro. Zool. Soc., 18-iO ; Conch. lUus. f. 83. 



Hah. Moluccas. 



The scidptiu-e of this species is of a character somewhat 

 similar to that of the Murex axicornis ; it agrees with it 

 also in the rounded aperture, closed canal, and finely den- 

 ticulated lip. Here, however, the resemblance ceases, for 

 its form and the growth of the fronds are totally different. 



Species 39. (Mus. Cuming.) 



Murex alabaster. Mur. testa trigono-fimformi, spird 

 testes longitudmeni aquante ; anfractibm transversim 

 liratk et striatis, liris Icevibus, superne aiigulatis, nodii- 

 lis duobm tribiisve subconspkids ad aiigidum armatis ; 

 trifariam varicosd, varicibm laminato-alatis, tuberculo 

 erecto, profunde canaliculato, ad angulum munitis ; in- 

 tm extusqtie ebwrned; canali brevitisculo. 



The alabaster Murex. Shell trianu;ularly fusiform, 

 spu-e equal to the length of the shell, whorls trans- 

 versely ridged and striated, ridges smooth, angidated 

 at the upper part, armed at the angle with two or 

 three rather conspicuous nodides ; tlu'ee-varicose, va- 

 rices laminately -ninged, furnished at the angle with 

 an erect deeply canaHcidated tubercle ; ivory white 

 within and without ; canal rather short. 



Reeve, Pro. Zool. Soc, 1845. 



Eab. Island of Cagayan, Province of Misamis, Island of 

 Mindanao (found on the beach) ; Cuming. 



Mr. Sowerby referred this extraordinary shell with some 

 doubt to the Murex acanthropterus ; its proportions are, 

 however, so utterly different that I venture to describe it 

 as a new species. No other specimen has been seen. 



Species 40. (Mus. Cuming.) 



Murex microphyllus. Mur. testa subfusiformi, cra.isl- 

 usculd, inter varices bi-trituberculatd, tramversim gra- 

 noso-liratd et striatd, liris extantibus, nodiferis ; iri- 

 varicosd, t^aricibu-s frondosis, froudibus superioribm 

 brevibus, subobscnris, inferioribus foliaceis ; columella 

 margine dentato-corrugato ; ferrugineo-fuscd, lirivi coii- 

 spicue nigris, aperturte fauce albd, columella luteo- 

 aurantid ; labro denticulato. 



The small-leaf Murex. Shell somewhat fusiform, ra- 

 ther tliick, with two or three elongated tubercles be- 

 tween the varices ; transversely granosely ridged and 

 striated, ridges prominently standing out, nodiferous ; 

 three-varicose, varices frondose, upper fronds short, 

 somewhat obscure, lower fronds foliaceous ; edge of 

 the colimiella dentately wrinkled ; rusty brown, with 

 the ridges conspicuously black, interior of the aperture 

 white, columella yellowish orange ; lip denticidated. 



Lamarck, Auira. sans vert. (Deshayes'edit.),vol.ix.p,575. 



Hob. Ceylon (found in rocky places) ; Dr. Siebald. 



This species is distinguished from the following by the 

 prominent nodulous structure of the ridges, and by their 

 very dark colour ; by the obscure blunted growth of the 

 fronds and absence of any pink colouring ; and by the 

 dentately wrinkled peculiarity of the edge of the colu- 

 mella. 



Species 41. (Mus. Saul.) 



Murex torrefactus. Mur. testa subfusiformi, trans- 

 versim eximie granosodiratd et striatd, inter varices 

 bituberculatd ; trifariam varicosd, varicibus frondosis, 

 froudibus brevibus, expanso-foliaceis,frondibus alternis 

 parvis, decumbentibus ; pallide ustulato-fuscd, liris sa- 

 turatioribus, frondibus intus rosaceis ; columelld lavi, 

 luteo-aurantid.
