species. The clouded tiger is a Malay species unknown 

 in China, while the Asiatic wild cat is a native of the 

 Himalayas and Malacca. It is clear, therefore, that before 

 Formosa was separated from the mainland the above 

 named animals or their ancestral types must have ranged 

 over the intervening country as far as the Himalayas on 

 the west, Japan on the north, and Borneo or the Philip- 

 pines on the south ; and that after that event occurred, 

 the conditions were so materially changed as to lead to 

 the extinction of these species in what are now the coast 

 provinces of China, while they or their modified descend- 

 ants continued to exist in the dense forests of the 

 Himalayas and the Malay Islands, and in such detached 

 islands as Formosa and Japan. We will now see what 

 additional light is thrown upon this subject by an 

 examination of the birds.
