Maxillary teeth none ; diapophyses of sacral vertebra dilated. 



The first two genera of this family approach the Cystignathida — 

 Migystomops resembling Paliidicola, and Pseudojpiryne resembling 

 Crinia ; whilst the last two, viz. Myohatrachus and Bhinophynus, 

 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 Migystomops 

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



The vertebrae are proooelian and without ribs. The diapophyses 

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

 degree as in the Pelohatidce. The coccyx is attached to two condyles. 



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

 phryne, 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.
