 as or a little longer than the upper eyelid, longer than deep; 

 canthus rostralis angular; loreal region slightly oblique, con- 

 cave; nostril about equally distant from the eye and the tip 

 of the snout; interorbital space about as broad as the upper 

 eyelid; tympanum very distinct, '/^ to Y, the diameter of the 

 eye. Disks of fingers and toes moderate, less than half the

 little larger than those of fingers; first finger equal to, or slightly 

 longer than second; fifth toe longer than third; toes entirely 

 or nearly entirely webbed ; outer metatarsals separated nearly 

 to the base; subarticular tubercles well developed; a small,
