Differs from the preceding species in the following points : — Snout 

 acutely pointed ; toes with a distinct rudimcDt of web ; metatarsal

The following genera probably belong to this family ; but as the 

 sternal structure has not been described, I cannot refer them to their 

 proper place : — 



XEiS-OEHTifA, Peters, Mon. Berl. Ac. 1863, p. ii2. 



" Habit of Engystoma ; toes free, with distinct disks ; fingers 

 free, without disks ; jaws and palate toothless ; tongue broad, heart- 

 shaped, adherent everywhere except a little in front ; end of snout 

 warty, nostrils lateral, at the tip of the snout ; tympanum distinct ; 

 no parotoids. Palmar and plantar surfaces smooth, without tu- 

 bercles. Diapopliyses of sacral vertebra dilated."

" Head rather small, indistinct from the body ; snout distinct, 

 pointed ; fingers and toes free ; tongue narrow, elongate, entire ; 

 tympanum distinct ; a large, flat gland on the loins ; prominence of 

 the first cuneiform bone elongate, pointed, small ; no vomerine nor 

 maxillary teeth ; diapophyses of the sacral vertebra weak, triangular."

tipper jaw toothed; diapophyses of sacral vertebra dilated. 



The characters of this family are the same as those of the pre- 

 ceding, except that the upper jaw is furnished with teeth. Calhtella 

 may be considered a toothed Hyiiopachus. and Cophyla a toothed 

 Callula. The precoracoids are either very weak, not taking any 

 share in the formation of the glenoid cavity, or absent. There is 

 no fronto-parietal fontanelle. The pupil is erect.
