Two genera are Malayan, one of which occurs in India and 
Ceylon, and the other in southern Asia and Africa ; five genera 
are American; two are African; one is American and African; 
and one is confined to southern Asia. 
There is no authentic record of the occurrence of a species of 
the order Caudata in the Philippine Islands or in the East Indian 
and Australian Archipelagoes. It is highly probable that a spe- 
cies may be discovered in Luzon. 
The order Salientia is well represented in the Malay and East 
Indian regions, and among its families and genera we may ex- 
pect to find evidences of faunal relationships and derivations. 
From Table 2 it will be observed that, of the seven families 
represented in the Oriental Region, only four are Philippine; 
two of these may be wanting in Luzon, since there is no authentic 
record of any member of either the Bufonidge or the Pelobatidse 
having been found there. Borneo on the one side, and Celebes 
on the other, each has representatives of the same four families 
but of no others. 
Table 2. — Distribution of the families of Amphibia that occur in the Orient. 
New Guinea, on the other hand, has no known representative 
of the Bufonidse, but has representatives of the Hylidae,® and 
very probably also of the Cystignathidse, which occurs in northern 
Australia. 
Japan and Formosa have representatives of four families, but 
the Hylidse, not the Pelobatidse, forms the fourth. 
Table 3 shows how poorly frogs and toads are represented 
° Casto de Elera lists Hyla chinensis Gunther from Luzon and Basilan. 
This is probably incorrect.
