14. Hyla dentata, Kef. 



A rare frog. I have only taken two specimens and these not 

 full grown. I know nothing of the habits of this species. 



15. Hyla citropus, P. & L., sp. 



Not common. Mr, Krefft gives Ryde and Hunter's Hill as 

 localities. I have not found it nearer than Waterfall j also in the 

 gullies at Mt. Wilson. In September last at Waterfall a pair of 

 this species were found in coitu on the damp rocky bed of the 

 creek close to water. They were caught without difficulty and 

 spawned in a dish containing water 24 hours later, the male never 

 relaxing his hold as far as observed. The male has a blackish 

 rugosity on the first finger of each hand. 



16. Hyla ewingii var. calliscelis, Peters. 



One of our commonest frogs, whose shrill notes may be heard 

 all the year round when the weather is not too dry. This species 

 probably breeds pretty nearly throughout the year. On June 

 16th, 1885, under a large stone about a yard from the edge of a 

 pond I took a pair in coitu, which allowed themselves to be caught 

 without trouble ; the female spawned on the evening of the 19th 

 the male so far as observed not having relaxed his position on the 

 female's back. The male is much smaller than the female, and 

 has a brownish rugosity on the first finger of each hand. The 

 ova have the pigmented pole orange. Similar ova in bunches 

 attached to twigs, blades of glass, &c., I have found in from May 

 to September, but some of it may have been laid by H. krefftii. 



What I take to be this species also sometimes (in different 

 years I have noted it in November, December, January and 

 February) spawns in the water-casks under similar conditions to 

 H. phyllochroa. The gardener has frequently seen them ; I have 

 seen the spawn, but have always been too late to see the fro^s 

 themselves ; from his description, and from the characters of the 

 spawn there can be I think little doubt about the species. In the 

 middle of November 1885 I found hundreds of advanced tadpoles
