 Voluta reflexa. Turton's Conch. Diet. 



Among the rejectamenta of rivers, &c., near their com- 

 'rjj munication with the sea. The variety 7. is found, unmixed 

 J. 'I with the common sort, in the clefts of rocks on the Swansea 

 ^ .^^ coast near high-water mark, within the influx of the tide. 

 J ..~,.This variety is less ventricose, and has the peristome not so 

 much reflected on the columella. I was at first inclined to 

 consider it a distinct species ; but the intermediate gra- 

 dations are almost imperceptible, and I have been assured 

 ,5-1 i it is found, together with the other varieties, in the crevices 

 ..,^+of the harbour walls at Weymouth. 



I suspect that the Voluta hyalina of Montagu is only an 

 imperfect specimen of this last variety.
