Fam. 3. UROPLATID^. 



Geckonidae, part., omn. auct. 



Uroplatidse, Boulenger, Ann. 8f Mag. N. H. (6) xiv. 1884. 



Tongue moderately elongate, simply papillose, slightly nicked 

 anteriorly. Dentition strictly pleurodont ; teeth numerous, small, 

 obtusely conical, with long cylindrical shafts. No pterygoid teeth. 

 Skull thin, much depressed ; a rather strong ligamentous postorbital 

 arch ; no frontosquamosal arch ; premaxillary single ; nasal single ; 

 frontal single ; parietals two. Vertebrae amphiccelian ; abdominal 

 ribs. Limbs well developed. Clavicles slender, not dilated prox- 

 imally ; interclavicle minute. Skin of head free from the skull ;

This family contains a single genus, the aberrant Uroplates of
