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 : — 



Xenorhixa, Peters, JNfon. Berl. Ac. 1863, p. S2. 



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

 free, without disks ; jaAVS 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. Diapophyses of sacral vertebra dilated." 



A", o.vyccphala, Peters, 1. e. {Bomhinator oxycephalus, Schlegel, 

 Handl. l)ierk. ii. p. 58, t. iv. f. 74). — N'ew Guinea. 



Adexomera (Fitz.), Stcindachn. Xovara, Amph. p. 37. 



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

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

 tj'mpanum 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." 



A. marmorata (Eitz.), Stcindachn. 1. c. — Brazil. 



4. DYSCOPHIDiE. 



Vpper jaw toothed ; diapophyses of sacral vertebra dilated. 

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

 ceding, except that tlie upper jaw is furnislicd with teeth. CallneUa 

 may be considered a toothed Hypopaclmi^, and Cophyla a toothed 

 1 CalhiJa. The prccoracoids arc either very weak, not taking any 

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

 no frouto-parietal fontanellc. The pupil is erect.
