the different species of Voluta: they nevertheless occa-

 amples new species. 



Though it is not the writer's present object to point 

 out all the rare shells in each genus, he cannot avoid 

 stating that the V. Junonia is incomparably the most 

 so of this. Very few examples of it being known, and 

 perhaps not more than four can be traced in Europe; 

 one of which exists in the select cabinet of W. J. Bro- 

 derip, esq. 



Many of the most rare and beautiful species of this 

 singularly elegant genus, have been figured by Swain- 

 son in the first Numbers of his Exotic Conchology, 

 with a verisimilitude that has never yet been equalled, 

 and probably never will be excelled by any artist. 

 This talent, combined with his scientific knowledge as 

 a Naturalist, must render the above work the most 

 eminent of its kind in this country; and it is earnestly 

 to be hoped that the unavoidable delay which has hi- 

 therto unfortunately attended the publication of the 

 succeeding Numbers may be shortly surmounted.
