snake, and a small non-dcsii^naled si)ccies, a specimen of which he sent to 

 Adelaide. 



The first-named may l)e the python; the jumping snake is a legless lizard 

 ( Lialis btirtonii. Gray), a specimen of which was secured hy Professor \\'ood 

 ]ones during his recent visit. It derives its local name from the peculiar and 

 rapid action with which it escapes from a grass tussock during the periodic 

 hurning of the scrub. 



What the black and brown snakes are we cannot yet say ; they may be 

 merely colour phases of a single species. The small unnamed snake presented 

 to the Museum (numbered R. 1157) by Professor \\^ood Jones proves to be an 

 example of 



Denisonia coronoides, Giinther. 



Hoploccplialiis coronoides, Giinther, Cat. Colubrine Snakes, Brit. Mus., 1858, p. 215. 



Denisonia coronoides, Boulenger, Cat. Snakes, Brit. Mus., iii., 1896, p. 336 (synonomy). 



The island specimen of this common South Australian species is quite 

 typical. It may be noted that the striations on the scales, said to be distinct, are 

 so fine that thev cannot be detected with the unaided eve.
