This tribe belongs, i^ar excellence, to the Old World. Two of the fami- 

 lies, Avhicli include but few species, belong to the New, viz, the Den- 

 drobatida) and the Colostethidte, and a few species of the Engystomidae 

 and Phryniscidai also occur in tropical America. The Eanidai have a 

 number of representatives in North A merica. The Cophylidai and Dys- 

 cophi{]a3 exist only in Madagascar, excepting one species of the latter 

 in India. The geographical distribution of the families is as follows : 





Anatia- 

 lian. 



Neotrop- 

 ical. 



Nearctic. 



Ethiopian. 



Patearctic. 



Palajotrop- 

 ical.

The resemblance to the Neotropical fauna displayed by Madagascar 

 in its lizards and snakes is also seen in the Batrachia in the presence of 

 a genus and four species of the family Dendrobatidse.
