 anhed, scarcely interrupted series behind, not extending outwards

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

 panum indistinct. First and second fingers equal ; two metacarpal 

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

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

 carried forwards along the bocby, the tarso-metatarsal articulation 

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

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

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

 the thumbs of the male; this proves that the male seizes the femaie under the 

 axilla, and not round the waist as in PelobatidcB and Bombinaloridw, with which 

 Limnodynastes bears great external resemblance.
