Remarks . — This species was discovered in Davao, Mindanao, 
in 1904, by E. A. Mearns. Two specimens were taken, one on 
Mount Apo, at an elevation of about 1,230 meters. This species 
differs from other members of the genus by the absence of the 
doubly arched ridge across the palate, and by the difference in 
the shape of the pupil of the eye. 
BUFONID^ 
No maxillary teeth present; diapophyses of sacral vertebrae 
dilated; vertebra procoelian and without ribs; the coccyx at- 
tached to two condyles; omosternum generally absent; distal 
phalanges obtuse or T-shaped ; pupil usually horizontal. 
The true toads belong to this group. It is a large family, 
cosmopolitan in distribution. There are comparatively few gen- 
era in the family. More than three-fourths of the known species 
belong to the genus Bufo. Two genera are known from the 
Philippines, Bufo and Nectophryne. 
Key to the Philippine genera of Bufonidse. 
a.’ Fingers slightly webbed; toes webbed, the tips more or less dilated 
into disks; pupil horinzontal; terminal phalanges T-shaped. 
Nectophryne Buchholz and Peters. 
Fingers free; toes more or less webbed, with or without disks; term- 
inal phalanges simple Bufo Laurenti.
