Pupil vertical; tongue elliptical, entire, free behind; a more 
or less distinct cutaneous ridge across palate between choanse, 
and another in front of oesophagus; tympanum hidden; fingers 
free; toes more or less webbed, sometimes very slightly; tips 
of fingers and toes blunt or more or less dilated; outer meta- 
tarsals united; no precoracoids; no omosternum; sternum car- 
tilaginous; diapophyses of sacral vertebrse moderately dilated; 
terminal phalanges simple. India, China, Japan, and East 
Indies. 
Remarks . — One species has been reported from the Philip- 
pines, on the doubtful authority of J. G. Fischer.^^ I have in- 
cluded the species because of the possibility of its occurrence. 
It is noteworthy that the genus Microhyla is the only represen- 
tative of the Engystomidse found in Formosa and the islands 
to the north. One species is confined to Formosa; a second 
inhabits the islands between Formosa and Japan proper.

In a recent letter M. Lazo, who is making a herpetological collection 
in the Batan Islands for the Bureau of Science, says that no batrachians 
of any sort are to be found there. This statement may be questioned and 
is remarkable if true. The Batan Islands lie between Formosa and Luzon.
