other species of the genus, varies much in size : the general length 

 is about 2 3 or 3 inches, but Lady Farquhar's shell is much larger 

 R.foliata appears to approach the genus Triton very nearly ' 

 and I cannot help thinking that a comparative examination of our 

 shell with the shells of that genus, will lead us to plaCte Triton 

 next to Ranella, instead of separating them from each other by 

 the genus Murex^ Lam., as is now done in the Systeme des ani-

These beautiful Murices were, as I am informed, found at the
