The great amount of variation w^ithin this form is to be 

 expedited purely to its diversified environment. Where condi- 

 tions are so unvarying as they are in Western Australia, we 

 do not find nearly the same amount of variation in the typical 

 variety. The tliickly timbered gullies of the Great Dividing 

 Range, the sandstone country around Sydney, and the rich, 

 sub-tropical, well-watei'ed districts of the Northern Rivers and 

 Queensland, all facilitate the development of specialised 

 variations. But, just why examples from the Great Dividing 

 Range should have a greater extent of webbing to the toes, or 

 why Sydney specimens should, on the whole, be smaller than 

 most others, is only to be accounted for by some local influence, 

 the character of which has yet to be observed. 



The brilliant colours which occur in the bi-eeding season are 

 due, as pointed out to me by Mr. Fletcher, to the abounding 

 vitality at this period, which in L. durstilis affects also the 

 mucous glands, causing them to become enlarged and to exude 

 freely. With regard to breeding coloui's I have two intei'esting
