I have two specimens of what I have no doubt is this species, 

 one from Katow, the other from Hall Sound. The ridge on the 

 tail is very feeble for a Hydrosaurus.

 This active little Lizard was very abundant on the rocky shores 

 of Darnley Island. It seems to be of all the Lizard tribe the 

 most subject to variety in colouring. I have specimens from 

 almost every place visited by the Expedition, and each place 

 seems to have its peculiar variety. The Darnley Island speci- 

 mens are of a sombre brown, with the white lateral line indis- 

 tinct. The Hall So and specimens are of a beautiful golden green 

 on the back, with conspicuous silvery white lateral streaks. Those 

 from Cape York, Cape Grenville, and other places, all differ more 

 or less, and yet there are no good grounds for supposing that they 

 are not all of the same species.
