EYRE : ON THE CLASSIFICATION OF VARIETIES. 



Ground Colour. 



Type — Yellow. 

 var. libellula, Risso. yellow. 



present paper may serve to draw attention to the necessity of a good 

 classification, and serve as a basis upon which to proceed. It does 

 not seem desirable to extend the table so as to embrace Co/our of 

 Band, as roseozonata, luteozonata, or other forms of colouring. 

 Further, it is possible for any one of the variations above-mentioned 

 to depart from the type in size or shape. The shell may be over- 

 grown, stunted, depressed, conical, scalariform, or sinistral. Two or 

 three such deviations have already been recorded in this country.
