This may be compared with Buccinum iJii^a^wm, but is smaller, 

 and proportionally shorter. Its aperture has the posterior callus, 

 and small, closed siphonal notch of Nassa. The sutural vitta is 

 very delicate ; and its peculiar coloration, especially its pale lace- 

 like reticulation, is quite distinctive. 



Buccinum funereum. Testa elongata, ovato-conica, lurido- 

 cinerea, striis tenuibus cincta : spira turrita, anfr. 6-7 superne 

 excavatis, inferne plicis longitudinalibus undatis : apertura angusta, 

 ovalis, dimidiam long, testee ; labro simplici, postice emarginato ; 

 columella rectiuscula ; fauce hepatica. Long. 1; lat. ^ poll.

Another of the peculiar group of liver-colored Buccina from 

 Australia, which seem to have a loose, porous, ash-colored super- 

 ficial layer, with a posterior notch to the aperture, {Tritonium 7) 

 It is well marked by the excavated constriction near the suture, 

 and the coronated appearance produced by the termination of the 

 folds at the middle of the whorls. 



Buccinum fossatum. ■ Testa tenuis, ovata, ventricosa, rufo- 

 cinerea, annulis et sulcis subequalibus cincta: spira conica, anfr. 

 7 convexis, supernis clathratis, ultimo ventricoso, postice declivi 

 et oblique fluctuate : antice brevissime rostrato ; rostro canali 

 valde eff'osso cincto : apertura lata, ovato-quadrata ; labro valde 

 arcuato; columella oblique lirata et callo tenui induta. Long.

Hob, Puget Sound and Mouth of Columbia River. 



Its thin structure, ventricose form, the very oblique folds on the 

 upper part of the large whorl, and the remarkable channel around 

 the base of the siphonal notch, are its chief characters. It be- 

 longs to the same group as N. trivittata, Say. On some speci- 

 mens a fine thread intervenes between the broader rings. 



Buccinum (Pollia) farinosum. Testa parva, solida, ovato- 

 rhomboidea, lutescens rufo cincta, spiraliter granulato-filosa, 

 longitudinaliter undato-plicata, plicis ad Sacutis demumnumerosis 

 et prope labrum acutum in varicem terminantibus : spira brevis.
