BUCCTNUM.— Plate IV. 



channelled above; lip simple; rusty brown, colu- 

 mella and interior of the aperture whitish. 



Martini, Conch. Cab. vol. iv. p. 70. pi. 196. f. 1312. 

 Bucci/ium Nonegicum, Enc. Meth. 



Hai. Coasts of England and Norway. 



Very like the preceding species, difi'ering only in having 

 the ridges more frequent and less strongly developed, and 

 the whorls less elevated one upon each other at the sutures. 



Species 34. (Mus. Cuming.) 



BucciNUM PAPYRACEDM. Bitc. testa ovatd, subfusiformi, 

 tenui, aiifractibm transversim tenuissime striatis ; colu- 

 mella suhexcavatd, lira, callosd superne munitd, stqird 

 cmialiculatd ; ferrugineo-fuscd, columelld et apertura 

 fauce allis. 

 The papyraceous Buccinum. Shell ovate, somewhat 

 fusiform, thin, whorls transversely very finely striated; 

 columella somewhat excavated, furnished at the upper 

 pai't with a callous ridge, channelled above ; light 

 rusty brown, columella and interior of the apertui'e 

 white. 

 Brtiguierb, Enc. Meth. Diet. no. 22. 



Hah. ? 



So closely do this and the two preceding species approx- 

 imate to one another, that they may prove to be nothing 

 more than difl'erent states of the same. 



Species 25. (Mus. Cuming.) 



Buccinum ovxim. Buc. testd ovatd, spird breviusmdd, 

 anfractibus rofi(ndatis,venirtcosis, Ifevigaik, labro tenui ; 

 eburned, epidermide teimi lidesceute indutd. 



The egg Buccinum. Shell ovate, spire rather short, 

 whorls round, ventricose, smooth, lip thin; ivory 

 white, covered mth a tliin yellowish epidermis. 



TuRTON, Zool. Journal, vol. ii. p. 366. pi. 13. f. 9. 



An Buccinmnfusiforme, Kiener (not of Broderip) ? 



Hah. Britain. 



I have no shell that comes so near to M. Kiener's figure, 

 B.fmiforme, as the present ; it is of rather a more elon- 

 gated form, and if on comparison it should prove distinct 

 must be re-named. 



Species 36. (Mus. Cuming.) 



Buccinum tenebrosum. Buc. testd tenui, mtbinjlatd, 

 spird mediocri, ad apicem mhplicatd ; anfractibus ro- 

 tuiidis, aut superne leviter depressis, spiraliter indis- 

 tincte carinatis, carinis fere obsoletis, labro acuta ; 

 intus extusque violaceo- aut Uvido-fuscd, columelld 

 supra nigricante. 



The dark Buccinum. Shell thin, somewhat inflated, 

 spii-e middling, shghtly plaited at the apex, whorls 



round or a little depressed round the upper part, 

 spii'ally indistinctly keeled, keels almost obsolete, lip 

 sharp ; violet or livid brown within and without, 

 columella blackish above.

pi. 5. f, 1, 2. 

 Hab. West coast of Davis's Strait, between Greenland and 

 North America (dredged from a blue clay bottom at 

 a depth of from fifteen to twenty fathoms) ; Warham 

 and Harrison. 

 An interesting species of which there are several exam- 

 ples in Ml-. Cuming's collection, described almost simul- 

 taneously with the present by Mr. Hancock, one of the 

 accomplished authors of the ' British Nndibranchiate Mol- 

 lusca ' issuing under the auspices of the Eay Society. The 

 new species of shells just described in the Magazine above 

 quoted, were dredged in a deep bay on the west coast of 

 Davis's Strait, thi'ough the zeal of Messrs. Warham and 

 Harrison, masters of whaling vessels belonging to the 

 port of Newcastle-on-Tyne. 



Species 37. (Mus. Cuming.) 



Buccinum tenue. Buc. testd fusiformi-ovatd, tenia, 

 spird subacuminatd, anfractibus subrotundis, lavibu-s 

 aut minutissim£ spiraliter striatis, concentrice plicato- 

 costatis, labro tenui ; sordidii albd. 



The thin Buccinum. Shell fusiformly ovate, thin, spire 

 rather acuminated ; whorls somewhat round, smooth, 

 or very minutely spu-aUy striated, concentrically pU- 

 cately ribbed, Up thin ; dead white. 



Gray, Zool. of Beechey's Voyage, p. 128. pi. 36. f. 19. 



Halt. Icy Cape. 



Well characterized by its concentric scalariform ribs. 



Species 28. (Mus. Cuming.) 



Buccinum Zealandicum. Buc. testd conico-ovatd, sub- 

 ventricosd, anfractibus spiraliter striatis, e suturis con- 

 centrice fortiter oblique semiplicatis,lahro subincrassato ; 

 albidd aut lutesceide, macuUs rubidis transversim ob- 

 loiigis inter plicas vittatd, aperturoe fauce aurantio- 

 luted. 



The New Zealand Buccinum. Shell conicaUy ovate, 

 somewhat ventricose, whorls spirally striated concen- 

 trically, strongly half-pbcated from the sutm-es, hp 

 I'ather thickened, wliitish or yellowish, filleted between 

 the folds with transversely oblong red spots, interior 

 of the aperture orange-ycUow. 



Hab. New Zealand. 



The rows of oblong red spots which encircle the upper 

 portion of the whorls in the interstices between the folds, 

 constitute a character by which this species may be easily 

 recognised.
