UNIVALVES. HALIOTIS. 



The Haliotis Iris, or Iris' Ear, (from New Zealand), is 

 celebrated for the superb radiance of its peari, which is 

 composed of the brightest iridescent colors imaginable, 

 finely contrasted with a green and gold bronze-like lustre. 

 The Splendid Ear from California, is equally to be admir- 

 ed for the exquisite beauty of its varied colors; added to 

 which, its magnitude renders it if possible a more magnifi-. 

 cent shell than the former. The size of the Haliotis Gigan- 

 tea, or Gigantic Ear, from New Holland, is also worthy of 

 notice, as it sometimes will exceed a foot in length. 



There are two species found in a fossil state; one is the 

 Haliotis Perversa, the other, the Haliotis Plicata, which 

 is found near Hildesia. The rest of the species are from 

 the shores of Europe, Africa, and India, where they ad- 

 here to the rocks like Limpets, and are with difficulty 

 removed.
