The neigliborliood of Sydney is very rich in BatracMans, and 

 I have found, besides several new species, many forms 

 which previously were only known from the north-east and 

 west coasts. There are altogether 19 species, namely : — 



Pteroplirynus varius 

 Limnodynastes dorsalis 



• Krefftii 



TJperoleia marmorata 

 Pseudophryne Australis 



Bihronii 



Hyperolius licolor, 30 miles from Sydney.

Believing that the habits of our Batrachians have never been 

 properly recorded, I will give some of my observations ; — If 

 we except a few species, we find that by far the larger number 

 of them are nocturnal ; those observed in the day time are 

 generally asleep, though some are active, but perhaps 

 disturbed only. During the breeding season, however (about 

 November), many otherwise nocturnal frogs may be seen in 

 broad daylight in search of their mates, the males calling in 

 their loud, often not unpleasing, voice, which at the beginning 

 of dusk is always loudest. The greater number of species 

 have deposited their ova in the beginning of December, 

 though I have reason to believe that some species breed at all 

 seasons, for I have taken Pseudojphryne Australis in midwinter 

 full of ova, and have obsf i ved larva of this and of several 

 other species in pools of x\ '^er about the same time. All the 

 Sylidce, however, deposit ' ! ' iir ova only once a year, generally 

 in November and Deceml 



The localities in which ■ le different species are found vary 

 considerably. Of Myxojphyc^s fasciolatus I know little, but 

 what I have seen of the single living specimen once in my 

 possession I believe that this frog is remarkably fond of lying 

 buried under moss in water, never making its appearance 

 before dark. The members of the family Cystignafhidce 

 frequent the water much more than the land, whilst such
