No ethmoid bone. Vomeropalatine bones, witli posterior separate 

 processes, «'xtending over the i»arasphenoid, and having teeth on their 

 inner margins. Prefrontals and pterygoids present. Parietals not 

 entbraiting the broad frontals. No dentigerous plates on the parasphe- 

 noid bone. An osseous pcstfrontosquamosal arch. Ceratohyal iree, 

 (M)nne<!ted with quadrate by ligament. Carpus and tarsas osseous. Ver- 

 tebra', opisthoccelous. No otoglossal caitilage. (Plate 34, ligs. 2-7). 



This family differs from the Salamandrida) oJily in its post fronto- 

 squamosal arch. Kiuliments of it already appear in some members of 

 the latter. 



The geneni of this family are all found in the Old World. One of 

 them is represented by two species in North America. They are dis- 

 tinguished as follows : 



I. Maxillary bone not reachinjj; quadrate. 

 (X, Ribs not pertoratinj; the skin.
