Walter Brown helped Angel Alcala to begin his herpetology-related works. Herpetology is concerned with the study of amphibians and reptiles. Together, they became the authors of “Observations on the Amphibians of the Mount Halcon and Mount Canlaon Areas,” a paper which was published in the 1955 edition of the Silliman Journal.Frog, any of various tailless amphibians belonging to the order Anura. The name ‘frog’ is often used to distinguish the smooth-skinned, leaping anurans from the squat, warty, hopping ones, which are called toads. In general, frogs have protruding eyes, no tail, and strong, webbed hind feet.
