264 GEOGRAPHICAL DISTRIBUTION OF AUSTRALIAN JBATRACHIA, 



the same species from Grafton, collected and forwarded by the 

 Right Rev. the Bishop of Grafton. 



H. gracilenta appears to be another example of species like 

 Chiroleples australis and others whose stronghold according to 

 present knowledge is Queensland, and which find their southern 

 limit somewhere about the northern boundary of New South 

 Wales. It is a very beautiful frog when alive ; the iris has an 

 inner portion golden shading into a circumferential ring of bright 

 coppery -red (visible sometimes even in spirit specimens) ; the body 

 above green or yellowish-green ; in the males the throat, part of 

 upper arm, shoulders, a line along the flanks bright yellow; the 

 under surface of the body and limbs tinged with yellow ; the 

 back of thighs purplish. The " white line on canthus rostralis, 

 outer border of upper eyelid, and above the tympanum " of Mr. 

 Boulenger's description is absent in my specimens. 



Mr. Helms says " this species may almost be called arboreal ; 

 most of the specimens were found on the leaves of the -arrow-root 

 plant ; during the day time they sit quite still with their eyes 

 closed, probably asleep ; when kept in the dark they assume a 

 much darker colour." I kept some specimens alive for some time 

 in a vivarium along with specimens of //. ccerulea ; individuals of 

 both species during the day time were invariably asleep, either 

 perched on the leaves of an Arum, or adhering to the sides of the 

 vivarium — to glass or wood indifferently. 



(d bis). From the Blue Mts. 



Hyla aicrea. 



Four specimens of this species were found by me last month 

 near Springwood, the first time I have happened to meet with it 

 on the Blue Mts. In the same locality in December last Mr. 

 Sloane and myself found two couples of H. citropus in cop., in a 

 little pool overshadowed by a fallen tree-trunk in a gully. This 

 is the first time I have seen this species from anywhere on the 

 Blue Mts., except Mt. Wilson.
