376 OVIPOSITION AIsD HABITS OF CERTAIN BATRACHIANS, 



similar spawn was noticed. About Sydney I have met with it in 

 different years in February, May, and July, 



At Mt. Wilson at the end of December I found a pair in coitu 

 under a stone near the water. Possibly this species breeds more 

 than once a year. 



7. Hyperolia marmorata, Gr., sp. 



Common under stones in the cool months. Females distended 

 with ova may be found in June ; once early in June a day or 

 two after bringing home some specimens three were observed in 

 coitu^ a second male clasping the first; of a number of speci- 

 mens kept in confinement for two months (July and August) two 

 on one occasion in August were noticed in coitu, but no ova 

 were deposited in either case. Of three specimens kept for some 

 days in September one female deposited over 200 separate ova in 

 a dry saucer, but they did not develop and probably had not been 

 fertilised. The ova had the pigmented pole black, the other 

 cream-coloured. 



8. Helioporus albopunctatus, Gr. 



Sydney is mentioned as a locality by both Boulenger and 

 Keferstein. I have never met with it, but have a very large old 

 male specimen in which the shagreening of the skin is more than 

 usually developed, given me by Mr. A. G. Hamilton, whose son 

 found it in a creek-bed at Hartley, Blue Mts. 



BUFONID^. 



9-10. Pseudophryne australis, Gr., sp., and P. bibronii, Gthr. 



Mr. Boulenger suggests that the latter may prove to be a mere 

 variety of the former ] but this view will not I think commend 

 itself to anyone who is familiar with the frogs in their natural 

 conditions. Not only is there the well-marked and very constant 

 difference in colour and pattern, but the frogs differ more or less 

 in temperament, in habits, and in regard to the breeding season.
