Tongue oval, slightly nicked behind. Vomerine teeth in two 

 arched series behind the choanse. Snout rounded, longer than the 

 greatest orbital diameter ; nostril a little nearer the tip of the snout 

 than the eye ; interorbital space narrower than the upper eyelid ; 

 tympanum two thirds or three fourths the width of the eye. Fin- 

 gers moderate, first much loager than second ; toes moderate, not 

 fringed ; subarticular tubercles moderate ; a small oval inner, and a 

 rather indistinct rounded outer metatarsal tubercle. The hind Hmb 

 being carried forwards along the body, the tibio-tarsal articulation 

 reaches hardly the eye. Skin smooth above, generally with large 

 flat glands on the flanks ; a glandular fold from the eye above the 

 tympanum to the shoulder, and generally another along each side of 

 the back to the sacral region ; a more or less distinct abdominal 

 discoidal fold. Brownish above, with dark spots generally arranged 

 in transverse bars on the back ; a black stripe along the canthus 

 rostralis and the temporal fold ; limbs cross-barred ; hinder side of 

 thighs black and yellowish marbled. Male with au internal sub- 

 gular vocal sac, and a strong conical tubercle on the inner side of 

 the first digit, and another, bi- or tricuspid one on each side of the 

 breast ; these tubercles covered, during the breeding-season, with a 

 black horny sheath.
