Maxillary teeth none ; diapophyses of sacral vertebra dilated. 



The first two genera of this family approach the Cystignathidce — 

 Eagystomops resembling Paludicola, and PsevdopJiryne resembling 

 Ovinia ; whilst the last two, viz. Myobatrachus and Rhinophrynus, 

 approach the Engystomatidce. 



The omosternum is generally absent : if present, it is reduced to 

 a narrow cartilage. The sternum is usually a cartilaginous plate, 

 which in a few cases is ossified along its centre ; in Engystomops 

 there is a well-defined bony style supporting a cartilaginous disk. 



The vertebra are proccelian and without ribs. The diapophyses 

 of the sacral vertebra are more or less dilated, but never to such a 

 degree as in the Pelobatidce. The coccyk is attached to two condyles. 



A fronto-parietal fontanelle is present in Engystomops, Pseudo- 

 pJiryne, and a few species of Bufo ; and in a few other species of the 

 latter genus the derm is completely involved in the cranial ossifi- 

 cation. 



In two genera the pupil is erect. 



The distal phalanges are simply obtuse, or T-shaped.
