lower jaw, the throat, the abdominal and subcaudal regions. The 

 upper region of the body and tail is likewise yellowish, but, since 

 each scale is provided with a chestnut-brown margin, the entire sur-

 band. 



LOG. This species was found under the bark of a tree, at Upper 

 Hunter, near Sydney, Australia.
