Maxillary teeth none ; diapophyses of sacral vertebra dilated. 



The first two genera of this family ajjproach the Cystignatliidcti — 

 Euf/i/stomojys resembling Paludicola, and Fseudoi^Tiryne resembling 

 Crinia ; whilst the last two, viz. Myohatracluis and Rlihioplirynus, 

 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 vertebrae are procoelian and without ribs. The diapoph5"ses 

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

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



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

 phrync, and a few species of Bvfo ; and in a few other species of the 

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

 cation. 



In two genera the pupil is erect. 



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