It is a curious circumstance in the geographical distribution of the 

 Haliotides, that few, if any, are to be found where Chitons abound ; 

 as if they exchanged places to a certain extent in the two hemi- 

 spheres. There are a few species from California, but along the 

 western coast of South America, where Chitons are most abundant, 

 not any are found, and only one small species, the H. pulcherrima, 

 at any of the islands of the Pacific. They inhabit the coasts of 

 China, Japan, Ceylon, Mozambique, Cape of Good Hope, Borneo, 

 and the Philippine Islands ; but the greater number of species, and 

 the most remarkable, are from New Zealand and the continent of 

 New Holland, displaying all the peculiarity of design which invariably 

 characterizes the fauna of those isolated regions. With the well- 

 known Halioiis tuberculata of the Channel Islands, all are familiar. 

 It is, however, a circumstance worth noting, that although such near 

 neighbours, and comparatively abundant, especially at the island of 

 Jersey, it is rarely collected on the coast of England. 



The Haliotides are found at low water, attached to the under sur- 

 face of masses of stone, and they fix themselves with great force to 

 the rocks, by suction, on the least alarm.
