Judging from the much smaller size of the Warburton River 
fossils in comparison with those from the Condamine River 
deposits, they appear to belong to a much smaller and _ hitherto 
undescribed species, for which I propose the name Varanus 
W ARBURTONENSIS. 
In the following table measurements are given of one of the 
two vertebre under consideration, and also one of those described 
by Prof. Owen from the Condamine River, Queensland.
