 When in Queensland a few years ago it was reported to me that 

 the animal could run supported upon its hind legs onl\'. By 

 others, however, this assertion was contradicted, and neither was 

 I successful in witnessing this most remarkable phenomenon of the 

 single living specimen I there had in my possession for a short 

 period. With examples obtained at Roebuck Bay, in the tropical 

 district of Western Australia, I was more fortunate, and was 

 enabled to fully satisfy myself that a bipedal mode of progression 

 represents its normal gait when the animal is traversing level

ground for any distance. In addition to having had the grati- 

 fication of securing other independent witnesses of the remarkable 

 method of locomotion exhibited by Chlamydosauriis, I have also 

 succeeded in obtaining several characteristic photographs, herewith 

 submitted, of this Lizard thus running. From one of the most 

 typical of these photographs the skilful taxidermist, Mr. Pickhai'dt, 

 has prepared the specimen likewise exhibited, and which will serve 

 to convey a yet more realistic impression of the aspect of the 

 running animal \ 



'^ By the kind courtesy of the proprietors of the ' Field ' the woodcut (Fig. 1 ) 

 executed in accord with one of these photographs, drawn from life at the 

 Zoological Gardens by Mr. Frohawk, and which appeared with a preliminary 

 notice of this lizard in that journal for August 3rd, is herewith reproduced. The 

 writer is likewise indebted to the same source for Fig. 2 (p. 717), representing 

 the animal in its ordinary resting attitude when on the ground.
