 developed knobs ; subarticular tubercles well developed ; inner meta- 

 tarsal tubercle long and narrow, rather weak; no outer metatarsal 

 tubercle; a distinct tarsal fold; heel of extended hind leg reaches

 with numerous minute, pointed tubercles on sacrum and on the upper 

 aspect of tibia, particularly towards the heel ; a few blunt tubercles

 blunt tubercles; a strong cutaneous fold from posterior corner of 

 eye to above and behind tympanum ; a distinct fold across the poste- 

 rior part of the interorbital space. Color (in alcohol) above very 

 dark chocolate brown, with faint indications of darker blotches 

 which form obscure cross-bars on the hind legs; hind aspect of 

 femur blackish with whitish marblings; underside pale, with dense

Remarks. — A large series of old, adolescent, and young specimens 

 from Mindanao, Basilan, Mindoro, and Luzon bear out the charac- 

 ters assigned to this new form. The younger specimens have a 

 narrower head, longer and more pointed snout, and narrower inter- 

 orbital space. It is therefore necessary, when comparing them with 

 related species, always to select specimens of exactly the correspond- 

 ing age. It is well to remember that the same size does not neces- 

 sarily indicate the same age.
