R ema1'ks.-This species was discovered in DavaQ, 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. BUFONIDlE No maxillary teeth present; diapophyses of sacral vertebra dilated; vertebrre proc<Elian and without ribs; the coccyx attached to two condyles; omosternum generally absent; distal phalanges obtuse or T -shaped; pupil usually horizontal. The true toads' belong to this family. It is a large family, cosmopolitan in distribution. There are comparatively few genera in the family. More than three-fourths of the known species belong to the genus Bufo. Two genera are known from the Philipp'ines, Bufo and N ectophryne. Key to the Philippine gene7'a of the BUfonii/J;E. a.'
