220 NATURAL HISTORY OF THE [chap. ix. 



are of peculiar species, except two, which range from. 

 Malacca into India. Of the cattle, one Indian species 

 reaches Malacca, while the Bos sondiacus of Java and 

 Borneo is also found in Siam and Burmah. A goat-like 

 animal is found in Sumatra which has its representative 

 in India ; while the two-horned rhinoceros of Sumatra 

 and the single-horned species of Java, long supposed to be 

 peculiar to these islands, are now both ascertained to 

 exist in Burmah, Pegu, and Moulmein. The elephant of 

 Sumatra, Borneo, and Malacca is now considered to be 

 identical with that of Ceylon and India. 



In all other groups of Mammalia the same general 

 phenomena recur. A few species are identical with those 

 of India. A much larger number are closely allied or 

 representative forms ; while there are always a small 

 number of peculiar genera, consisting of animals unlike 

 those found in any other part of the world. There are 

 about fifty bats, of which less than one-fourth are Indian 

 species ; thirty-four Boclents (squirrels, rats, &c), of which 

 six or eight only are Indian ; and ten Insectivora, with one 

 exception peculiar to the Malay region. The squirrels are 

 very abundant and characteristic, only two species out of 

 twenty-five extending into Siam and Burmah. The 

 Tupaias are curious insect-eaters, which closely resemble 

 squirrels, and are almost confined to the Malay islands, as 

 are the small feather-tailed Ptilocerus lowii of Borneo,
