668 GEOGRAPHICAL DISTRIBUTION OF AUSTRALIAN BATRACHIA, 



The broad facts relating to the geographical distribution of these 

 species may be summed up somewhat as follows : — 



(1) Certain species are apparently very widely distributed, 

 twelve of the fourteen species recorded from the West Coast 

 occurring also on the East Coast, as well as, in some cases, 

 in intermediate (coastal) districts. 



(2) Some species are widely distributed in, but as far as present 

 knowledge goes ajDpear to be confined to, one or other of these 

 regions, such species at present being more numerously repre- 

 sented in Eastern Australia (possibly in some measure due 

 to more systematic collecting in more accessible localities). 



(3) Other species are still less widely distributed, some being 

 remarkably local, or at least recorded only from single locali- 

 ties (e.g. Hyla jervisiensis, H. dimolofs). 



(4) Little is known of the Batrachia of districts remote from the 

 coast, the habitats recorded being with but very few excep- 

 tions and these for only few specimens (e.g. Chiroleptes flaty- 

 cejohalus, Notaden hennettii, Helioporus pictus) coastal. 



(5) The falling off in the number of species in the southern 

 colonies is possibly and very probably in some degree rather 

 apparent than real. 



As Batrachia are not confined to the coastal districts, and as 

 the species were originally described chiefly in instalments as 

 representatives of new species reached Europe or America, and 

 without I'eference to the general batrachian fauna of the particular 

 localities whence the types came, it is obvious that the subject of 

 geographical distribution is not yet exhausted. Indeed, Port 

 Jackson perhaps excepted, it is hardly possible at present to draw 

 up an exhaustive list of tbe frogs of any particular place, notwith- 

 standing that some species have been recorded from numerous 

 localities. 



As a first small contribution towards a more detailed knowledge 

 I now propose to record three collections from localities in this 

 colony sufficiently remote from one another to be of interest, two
