Upper jaw toothed; diapophyses of sacral vertebra not, or but 
very slightly, dilated. 
The members of this family show no great differences in the 
structure of the sternal apparatus. The precoracoids are always 
present, their axis being parallel with that of the coracoids, and 
their distal extremity resting upon that of the latter. The preco- 
racolds are much weaker than the coracoids. In most genera an 
omosternum and a sternum are well developed and furnished with 
a bony style. In Oxyglossus, Hyliwalus, and Prostherapis the 
sternum lacks the bony style, and so does also the omosternum in 
Nannophrys and Phyllodromus. In Colosiethus, according to Cope, 
the omosternum is totally absent. 
The vertebree are proceelian. The coccyx is attached to two con- 
dyles. There are no ribs. 
A fronto-parietal fontanelle is constantly apnea 
The distal phalanges may be simple, pointed, or subtriangular, 
T-shaped, Y-shaped, or even claw-shaped (Hylambates), the latter 
structure being met with in the Hylide, Amphignathodontide, and 
Hemiphractide only.
