The large number of one hundred and sixteen specimens, 

 representing thirty-seven species, proves the abundance of this 

 class of animal life in the arid regions of Australia traversed by 

 the Expedition and also indicates the zeal and energy of the 

 collector under the peculiarly difficult circumstances of Austra- 

 lian exploration. 



Five species of this order have lieen hitherto undescribed ; of 

 these four were collected for the first time by the Elder 

 Expedition and a full description of them is here given. One 

 species having been previously collected by Dr. Stirling on the 

 occasion of His Excellency's transcontinental journey, its 

 description is reserved for the zoological report of that expedition 

 shortly to be published. 



The classification and details of measurement are those adopted 

 by Boulenger in the " Catalogue of Lizards in the British 

 Museum Collection." 



The following families are represented: — Geckonidas, 8 species; 

 Pygopodid<i>, 3 species; Agamidse, 10 species; Varanidie, 2 

 species ; Soincidie, 14 species.
