Habit of Alytes ohstetricans. Tongue subcirciilar, entire or 

 slightly nicked behind. Vomerine teeth in a straight or slightly 

 arched, scarcely interrupted series behind, not extending outwards 

 beyond the choanae. Snout rounded, as long as the orbital dia- 

 meter; nostril equally distant from the e^'e and the tip of the 

 snout; interorbital space narrower than the upper eyelid; tym- 

 I^anum indistinct. First and second fingers equal ; two metacarpal 

 tubercles ; toes rather short, one-third webbed, the web extending 

 as a fringe to their tips ; subarticnlar tubercles well developed; inner 

 metatarsal tubercle large, shovel- shaped. Tlie hind limb being 

 carried forwards along the body, the tarso-metatarsal articulation 

 reaches the eye, or between the eye and the tip of the snout. Skin 

 of upper surfaces with small smooth tubercles. Olive above, marbled 

 with darker : generally a light, dark-edged cross band between the 

 eyes; sometimes a light spot on the occiput: sometimes a light 

 vertebral stripe ; beneath immaculate. Male with a subgular vocal 

 sac and, during the breeding-season, brown rugosities on the inner

* The female has on the breast two cicatrices which are evidently caused by 

 the thumbs of the male ; this proves that llie male seizes the female under the 

 axilloe, and not round tlie waist as in Fclohafidm and BomhinaloridcB, with which 

 Limnodynastes bears great external resemblance.
