6. The Australian Eegiok. 



Besides Australia, this Region comprises Tasmania, New Zealand, 

 New Guinea, and the islands of the Pacific. Three well-marked 

 Subregions maybe distinguished : — 1. the Austromalayan, comprising 

 New Guinea and neighbouring islands, Cape York, and Polynesia ; 

 2. the Australian, comprising the continent of Australia and 

 Tasmania ; and 3. New Zealand. 



The general character of the Australian fauna is negative, and 

 consists in the absence of Apoda, Gaudata, Bufo, and liana (except 

 in the Austromalayan or transitional subregion). The fauna consists 

 mainly of the two families Cystignathidaz and Hylldce, which are 

 likewise most developed in Tropical America. 



The Austromalayan Subregion presents an interesting blending of 

 the Indian and Australian faunas. To the former must be reckoned 

 12 Firmisternia, belonging to 6 genera of the families Ranidce and 

 Engystomalidce, and 3 Pelobatidce, each of which is the type of a 

 genus restricted to the subregion. Eleven Hylidce (Ryla and 

 Hylella) are Australian types. A curious fact is the occurrence 

 (according to Peters) of a third species of the African genus Phry- 

 nomantis in Amboyna and Batanta. The small islands of the Pacific 

 are inhabited by but few species, viz. a Bana and a Hyla in the 

 Solomon Islands, and 3 Cornuferi in the Caroline and Fiji Islands ;
