 V. DER HOEVEN en DE VRIESE, Tijdschr. voor not. Gesch. I. 1834, PI. viz. 

 fig. 2, DUM. et BIBR. Erpet. V. PI. 56. This animal, discovered by the 

 traveller S. MUELLER on the west coast of New Guinea, is justly sepa-

 many. 



Tribe I. Lacertce. Maxillary teeth with a hollow base, 

 growing to the inner margin of jaws, anterior subulate, posterior 

 obsoletely bicuspid or tricuspid, subcompressed. Head scutate. 

 Ventral scales mostly quadrangular, arranged in transverse rows. 

 Tail long, fusiform, sometimes rotundato-quadrangular at the base, 

 elsewhere round. Tongue oblong and triangular, beset with scale- 

 like papillae, divided at the apex into two short, acuminate, smooth 

 slips.
