* T. a pyramidal shell, with five or six volu- 

 tions ; ribs raised, distant ribs ; minute ; inha- 

 bits sandy shores. 



t Mr. Montagu conjectures tiiat the animal which inhabits 

 this shell, might have contributed to supply the celebrated Ty~ 

 rian dye, as a beautiful purple liquor can be obtained from it ; 

 but the color does not appear so permanent as that procured from 

 the Buccinum Lapillus ; the latter having been once fixed, is. 

 not affected by the application of acids, alkalis, or alkohol. See
