Hedley. There are also two unlocalised specimens and one 

 from Herbert River, North-east Queensland. 



L. olivaceus differs from L. tasmaniensis which it 

 replaces on the north and central coast of Queensland,, 

 by the following characters : — The toes are cylindrical, 

 generally devoid of a basal web or any trace of fringe ; 

 the sub-articular tubercles are very prominent and conical ;. 

 only one metatarsal tubercle always ; the back has promin- 

 ent warts ; the snout is more pointed ; and more or less 

 by the broken up nature of the markings of the back, and 

 their tendency to distribution in characteristic bands. 



The four species of Limnodynastes so far noticed, 

 e.g., L. tasmaniensis, platycephdlus, fletcheri, and olivaceus,. 

 form a natural group more or less distinct from the rest 

 of the genus. They are closely allied to each other, and 

 it becomes a question whether we should regard them as 

 distinct species ,or as geographical varieties of one, L. 

 tasmaniensis. Of all but L. platycephalus I have examined 

 a series of specimens, but of that species I have only seen 

 one. This, however, certainly supports its separation from 

 L. tasmaniensis. The distinguishing characters of the 

 four species are of relative value, and although to an extent 

 variable, do not merge completely with one another. The 

 habitat of each, with the exception of L. platycephalus, 

 is distinct. While at present their vaHdity as species 

 is perhaps a matter of opinion, I am inchned to beheve 

 that they are correctly regarded as such.

L. dorsalis, v. dumerilii, Ptrs. (part). Fry, Rec. Austr. 

 Mus., X, 1913, pp. 26-28, 30, pi. iii, fig. 2. 



A variety proposed for north and central coastal 

 Queensland examples, differing from L. dorsalis v. dumerilii 

 confined to South Australia, Victoria, Tasmania, New 

 South Wales and Southern Queensland, in the following 

 characters : — The habit is excessively stout and the size 

 very large ; the hind-limb is very short being 1.1 to 1.25
