IMUREX.— Plate XXXIV. 



reted, sutures slightly excavated; whorls depressed 

 at the upper part, encii-cled with obscure transverse 

 obtuse ridges and punctured striae, with a superficial 

 tubercle between the varices ; thi'ee-varicose, varices 

 thin, erectly winged, the last very widely expanded 

 and faleately recui-ved at the upper part ; aperture 

 small ; canal rather short.

Hah. Japan ? 



For this new and extraordinary shell I am indebted to 

 the kindness of the Rev. W. E. Crotch, whose manuscript 

 name eurypteron, (fi'om ebpvs, widely extended, and -mepov, 

 wiiuj), I feel great pleasure in adopting as being peculiarly 

 expressive of its remarkable alate gi-owth. It approaches 

 nearest to the Murex falcatm, but in that species there are 

 five varices on a whorl, whilst in this there are but thi-ee, 

 and the winged expansions of the Mtirex falcatus are folded 

 over at the superior margin. The specimen here fig\ired, 

 and which is I believe unique, was received from Holland, 

 and is supposed to have come from Japan.

 tudinally with five varices of spines, transversely 

 slightly gi'ooved, the last spines of the whorl longer,

Hob. Cook's Straits, New Zealand. 



As I have not had the pleasiu'e of seeing this interesting 

 species I am miable to give au original figure or descrip- 

 tion. There is, I believe, a smaU specimen of it in this 

 country figm-ed some years since by Mi-. Sowerby, in his 

 ' Conchological Illustrations,' but he cannot recollect in 

 whose possession it is. 



Species 178. (Mus. Cuming.) 



MuEEX MAEGAEiTicoLA. Mur. testd ovatd, squamarmi 

 liris angustis undlqiie cinctd, anfractihus superne leviter 

 angulatis, nmUifariam varicosis, varicibus obtuso-ro- 

 tundaiis ad angidum compresso-nodosis ; albd, squama- 



rum liris purpureo-nigricantibus, apertura fauce riola- 

 ced, prope marginem dentatd ; canali brevi. 



The peael-shell-inhabiting Mueex. Shell ovate, 

 encu'cled thi'oughout with narrow ridges of scales, 

 whorls slightly angled at the upper part, multifari- 

 ously varicose, varices obtusely rounded, compressly 

 nodose at the angle ; white, ridges piu-ple-black, in- 

 terior of the aperture violet, toothed near the margin ; 

 canal short. 



Beodeeip, Pro. Zool. Soc, 1832. 



Hab. Lord Hood's Island, Pacific Ocean (found adhering 

 to the Meleagrina margai-itifera). 

 A shell of very interesting sculpture, consisting of a 



succession of nai-row piu-ple-black ridges of fine scales upon 



a white ground. 



Species 179. (Mus. Cuming.) 



Mueex Edwardsii. Mur. testd ovatd, crassiusculd, tram- 

 versim irregulariter crebriliratd, longitiidinaliter pli- 

 cato-tuberculatd, varicibus hiterdum duobus vel tribus, 

 interdum niillis ; viridi-fuscd, aperturce fauce violaced, 

 prope margineiii dentatd j canali brevi. 



Edwaeds' Mueex. Shell ovate, rather thick, transversely 

 irregulai'ly closely ridged, longitudinally pUcately 

 tubercled, sometimes two or thi'ee varices, sometimes 

 none ; greenish-brown, interior of the apertui-e violet,

Hab. Mediterranean. 



The varices are so irregidar in their appearance that the 



generic character of the species appears to oscillate between 



that of Murex and Purpura. 



Species 180. (Mus. Nonis.) 

 Mueex toeosus. Mur. testd globoso-ovatd, veittricosd, 

 costis grandibus tumulosis, interstitiis profunde e.cca- 

 vatis, lira squamatd percurrente, cingulatd; varicibus 

 tribus aut pluribus, obtusis ; fused; spird brevissimd. 

 The lusty Mueex. Shell globosely ovate, ventricose, 

 encii'cled with large tumulous ribs, the interstices be- 

 tween which are deeply hollowed, with a squamate 

 ridge running along ; varices three or more in num- 

 ber, obtuse ; brown ; spu'e very short.
