ASIATIC GENERA OF QUADRUPEDS, ETC. 55 
peculiar to these seas, and many appear under the most 
grotesque forms: among these, the Jxa cunaliculata 
(fig. 18.) of Dr. Leach * deserves being mentioned. 
Another species, Iva 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.

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
