Species 61. (Fig. a, Mus. Cuming ; Fig. b, Mus. Noms.) 



MuREX FALCATUS. Mtir. testa abhreviato-fnsiformi, spird 

 breoi, angulato-turritd, liris parvis longitudinalihis et 

 tranmerm apicem vermis clathratis ; qidnqiievaricosd,

The hooked Mdrex. Shell abbreviately fusiform, spire 

 short, angularly tmTeted, latticed towards the apex 

 with small longitudinal and transverse ridges ; five-

Eadem. Murex aduncus, Sowerby. 



Hai. Japan. 



By permission of Thomas Noms, Esq., 1 have repre- 

 sented at Fig. 61 (7, the specimen described by Mr. Sowerby 

 under the name of Murex adiincus. It appears merely to 

 exhibit a slight modification of growth without any varia- 

 tion of specific importance. 



Species 62. (Mus. Cuming.) 



Murex pinniger. Mur. testd fusiformi, superrie obsolete 

 liratd, tuberculo solldo prominulo inter varices ; triva- 

 ricosd, varieibus alaformibus, supenie laciniato-fulcatis, 

 ad ba-sem alatis; pterpurascente-alid, fmco hie illic 

 tinctd et punctata ; aperturd pecuUariter parvd. 



The wing-bearing Murex. Shell fusiform, obsoletely 

 ridged at the upper part, with a solid prominent tu- 

 bercle between the varices ; three-varicose, varices 

 wing-like, laciniately hooked at the upper part, winged 

 at the base ; pm-pUsh white stained and spotted here 

 and there with brown. 



Broderip, Pro. Zool. Soc, 1832. 



Murex cristat/is. Gray (not Brocchi). 



Hai. XipLxapi, West Columbia (dredged from sandy mud 

 at the depth of eight fathoms) ; Cuming. 



The varices of this species are peculiarly thin and flat- 

 tened though a little waved and serrated at the edge ; and 

 they are developed in a cmious winged manner at the 

 base. 



Species 63. (Mus. Saul.) 



Murex phyllopterus. Mur. testa trigono-oblongd, stib- 

 fusi/ormi, inter varices obtuse tubereulutd, transversim 

 liratd, liris latiusculis, subobsoletis, distantibus; triva- 

 ricosd, varieibus radiatim lamiuatis, alaformibm ; alba, 

 fasciis latiusculis castaneo-fuscis inter varices conspicue 

 pictd ; canali breviusculo. 



The leaf-winged Murex. Shell triangidarly oblong, 

 somewhat fusiform, obtusely tubcrculated between 

 the varices, transversely ridged, ridges rather broad, 

 somewhat obsolete, distant ; tliree-varicose, varices 

 radiately laminated, wing-bke ; white, conspicuously 

 painted between the varices with rather broad chesnut 

 brown bands ; canal rather short.

 Murex trialatus, Sowerby. 



Eah. ? 



Tliis shell may probably be a dark banded variety, and 

 not the type, of Lamai'ck's species ; it is, however, the only 

 specimen at present known in this country, and the only 

 one I remember to have seen. 



Species 64. (Mus. Cuming.) 



Murex acanthropterus. Mur. testd trigono-fusiformi, 

 anfractibws mpeme angulatls, transversim liratis et 

 striatis ; triearicosd, varieibus Inminato-alatis, mem- 

 branaceis, superne canalicidato-falcatis ; albd, interdum 

 fuscesce>ite sparsim tincta ; canali longiusculo. 



The spine-winged Murex. Shell triangidarly fusiform, 

 whorls angulated at the upper part,, transversely ridged 

 and striated; three-varicose, varices laminately winged, 

 membranaceous, canalicidately hooked at the upper 

 part ; wliite, sparingly stained with light brown ; ca- 

 nal rather long. 



Lamarck, Anim. sans vert. (Deshayes'edit.),vol.ix. p. 577. 



Eab. ? 



The varices of this species exhibit a very peculiar canal- 

 iculated structure at the upper part, which ranges on the 

 spire in rows of prominent spine-Uke hooks. 



Species 65. (Mus. Cuming.) 



Murex Gambiensis. Mur. testa fusiformi, infeme atten- 

 uatd, solidiusculd, tramversim obsolete striata, tuber-
