Mr. Bell on a new Genus of Scincide, 393 
brushwood, or even under the surface of the ground, where it would 
force a passage in the pursuit of insects and worms, on which all these 
animals probably feed. 
The arrangement of the scales in the Amphisbenide generally, is 
calculated to afford in an equal degree the power of progression and retro- 
gression; as they are in no case imbricated, but placed side by side, 
with the posterior as well as the anterior and lateral margins closely con- 
nected with the skin. They are the only Reptilia which can with strict 
propriety be termed double marcheurs.
