Walker, that we dare not from the fingle, and fomewhat 

 worn fpecimen before us, give it as dillincl. Tliere has 

 certainly been a confiderable degree of confiifion about 

 Walker's fliell ; amongft the many and valuable commu- 

 nications of that ever to be lamented friend of fcience Mr. 

 BoifS, a minute fpecies of Valuta was fent to us for com- 

 parifon, and from which a drawing was taken. By com- 

 paring this fliell with the figure of that, we are now obliged 

 to form an opinion ; for by fome unaccountable overfight, 

 our late worthy friend had, in his Tejlacea Minula Rariora 

 cabinet, affixed this name to the young Bulla obtufa ; and 

 we cannot help doubting whether Walker did not a6lually 

 give that Ihell for it, and by fome fuch miltakc thofe two 

 fliells became confounded. 



That which we now offer, and appears fo like the original 

 fpecimen of V. alba, from Mr. Boys, is equally minute, and 

 ovate, with four plications on the columella : the aperture 

 narrow, and open at the bafe like V. pallida, but it has not 

 the contour of that fhell ; the fuperior volutions are fome- 

 what worn, and obfolete, but the apex is fufficiently pro- 

 duced to indicate three or four. There are on the columella 

 befides the folds, fome flight denticulations higher up. 



Found in fand from the coaft of Dunbar, by Mr. Laskey.
