Length of snout about equal to distance from eye to ear- 

 opening. Upper-surface slate-coloured ; a vertebral line and two 

 lateral lines of a darker shade. The dark vertebral line divides 

 into two separate lines on the neck, which unite again at about 

 two-thirds of the distance between the eyes and tip of the snout. 

 A white labial band is prolonged along the sides of the body; 

 this band is bordered on each side by minute white spots. Under- 

 surface light grey; a white line along the middle of the throat, 

 which bifurcates at about 20 mm. distance from snout, and the 

 two branches extend over the tail. 



The measurements of the second specimen are as follows : —

Film. AGAMID^E. 



Ampjiiboluhus maculatus, Gray. 



Tliree specimens — two apparently adult and one young — of 

 this beautiful lizard were obtained in the Barrow Ranges, and a 

 fourth in the Victoria Desert near Queen Victoria Springs. 



All these agree with Bouleuger's description except in respect 

 of their markings, which are as follows : — Above brick-red with 

 a series of small bluish-grey spots along the vertebral line. The 

 lateral lines are composed of similar spots, which are partly 

 confluent. Four bluish-grey lines mark the upper-surface of the 

 anterior third of the base of the tail ; the two median then 

 becoming confluent, three lines are continued to the tip. The 

 remainder of the tail, sides of body, head, throat as well as a 

 large patch, which covers most of the under-surface and the 

 inner-surface of the hindlimbs are deep-black, but a narrow 

 yellowish uncoloured streak on each side of the body is left, 

 which connects the forelimbs with the hindlimbs. The remainder 

 of the under-surface as well as the lips are yellowish-white.
