386 OVIPOSITION AND HABITS OF CERTAIN BATRACHIANS, 



them to have been H. freycineti. In the middle of last April I 

 found a number of tadpoles just about completing their metamor- 

 phoses, about 35 mm. long, the body 15x7 mm. Towards the 

 end of March in the previous year numbers of young frogs which 

 had only recently taken to land were common about the edges of 

 swamps at Botany. Three males taken as late as the beginning 

 of April have a brownish rugosity on the first finger of each hand. 

 There can I think be little doubt that this species breeds in spring 

 and summer, and oviposits in water in the ordinary way. This 

 species may possibly hibernate buried in the mud, as unless the 

 frogs travel some distance in some localities there is a dearth of 

 suitable shelter. 



23. Hyla dimolops. Cope. 



This species, mentioned in the British Museum Catalogue as 

 from Sydney, I have never met with. 



24. Hylella bicolor, Gr., sp. 



I have never met with this frog. Krefft gives as localities " 30 

 miles from Sydney, and Blue Mts." In Professor Parker's third 

 memoir " On the Development of the Skull of the Batrachia " 

 {Phil. Trans. 1881, p. 158) the locality Dogtrap Road, Parramatta 

 is mentioned for it. 



In regard to the foregoing list the following points may be 

 noticed : — Limnodynastes ornatus occurs in Keferstein's list * 

 under the two names Platyplectrum inarmoratum and F. 

 ornatum, for each of which the locality Sydney is given. In 

 Steindachner's list f Sydney is given as a locality for Cryptotis 

 hrevis. 1 have specimens of the former from Mudgee collected by 

 Mr. A. G. Hamilton, and I have found examples of the latter in 

 gullies in the Blue Mts.; but I have not found them in the 

 County of Cumberland nor have I met with any who has. These 

 two, and a similar remark possibly applies to Helioporus alho-
