peculiar to these seas, and many appear under the most 

 grotesque forms : among these, the Ixa canaliculata 

 {fig. 18.) of Dr. Leach* deserves being mentioned. 

 Another species, Ijea inermis, when its limbs are drawn 

 under its shell, might easily be mistaken for a piece of 

 coral. The most valuable pearls in the world are pro- 

 duced from a species of pearl oyster {Margarita Si- 

 nensis Leach), which seems confined to the Indian 

 Ocean ; those of the American seas being of a totally 

 different species. 



(76.) The genera of quadrupeds, and their minor 

 divisions, which more particularly characterise the 

 Asiatic province, are the following : the numbers de-

(77.) The birds peculiar to the Asiatic range belong 

 to the following geographic groups, not one of which 

 occurs in Europe, although several of the European 

 forms extend to Asia. The present confusion in orni- 

 thological nomenclature renders an estimate of the
