LYGOSOMA (SIAPHOS) ^QUALE, Gray. 
Some years ago this was doubtfully recorded for Queensland in our register, 
but there was some difficulty as to locality. Three specimens, however, were 
recently secured at Mount Tambourine by Mr. H. Hacker. 
HEMISPHiERIODON GERRARDII. Gray. 
Living specimens of this large skink-lizard demonstrate the somewhat 
surprising fact that the caudal extremity is prehensile. The animal is able to 
<3ircle its long tail around a suitable object and can hang thereby. This muscular 
flexibility is in marked contrast to the brittleness of the tails of most skinks. 
Tiliqua longicmida, He Vis,* is a synonym of this species. It should be noted 
that the colour characteristics as stated by Boulenger'" are not constant and 
occasionally the throat markings are absent.
