From the foregoing facts the following conclusions may be 

 drawn : — ■ 



(1) Of about thirty-four species with which N.S.W. may at 

 present be credited, all but five are to be found inhabiting the strip 

 of coast east of the Dividing Range extending from the northern 

 border to Jervis Bay (the district to the south of this being left 

 out of consideration at present), the majority of which are more or 

 less universally or widely distributed (Australian) species, several 

 are species better represented in Queensland which appear to reach 

 their southern limit in the northern part of the district in ques- 

 tion (e.g. Chiroleptes australis, Pseucloijhryne coriacea, perhaps 

 also Phanerotis) while at least four (Hyla dentata, H. citroipns, 

 H. jervisiensis, and H. dimolops) are not at present known to 

 occur out of it. 



(2) Of the thirty-four species above-mentioned eighteen (com- 

 prising representatives of the three dominant Australian families) 

 are now recorded as occurring in the districts of the colony west 

 of the Dividing Range, of which five (Chiroleptes 2^i(itycephcdus, 

 Limnodynastes fietcheri, Helioporus pictus, Notaden hennettii, and 

 Uyla Tidyella,) are not known to occur in the coast region of 

 N.S.W. ; the remainder being more or less widely distributed 

 species. The common frogs of the interior of the colony thus 

 include such species as Limnodynastes tasmaniensis, L. dorsalis, 

 Crinia signifera, Hyperolia marmo7-ata, Notaden hennettii, Hyla 

 ccertdea, H. aurea, and H. peronii. The rest, or some of them, 

 may perhaps be widely distributed but appear to be rarer ; or have 

 not been collected from sufliciently numerous localities to furnish 

 data for any very definite statements about them, 



A few species occurring in the Richmond and Clarence district, 

 or further to the north, shade off into the interior, though not 

 known to occur much further to the south, or only sparingly ; 

 such are Limnodynastes ornatus, L. sahninii, and Id. rubella ; a 

 glance at the map is suggestive of a possible derivation arising 

 out of the proximity of the sources of the eastei'n and western 

 waters in this part of the colony.
