PLATE X 



Figure. 1,2. Voluta arniata?, Lamarck, variety. 



Habitat, unknown. 



Remarks. — This rare shell has been in my collection for several years, and 

 I have always been under the impression that it was a distinct species. Having, 

 however, lately received the Livraisons of Mons. " Kiener's Iconographie," 

 which contain figures of the Volutes, and upon examination of the figures of the 

 Voluta armata, Lam., and its varieties, I am inclined to think this may be one of 

 them. Not having received the text, I am only able to judge from the figures. 

 My specimen has three large plaits on the Columella, with an additional small 

 one above the others. It is a very delicate, light shell, although from its size 

 one would suppose it to bo heavier than it is. Length 8 inches, breadth 

 4 inches.
