The genera and species of the family Draconina are as follows : 

 1. Draco. Head small. Nostril in a scale, rather tubular on the side 

 of the face-ridge. Tympanum of the ear visible, opaque, white. They 

 live on trees, walking with agility with their wings folded on their 

 fides, but they expand them and use them as a parachute when they 

 throw themselves from the tops of trees. They spread out their 

 pouches as they lie on the trunks of the trees. Scales unequal, some 

 larger, keeled. Nape crested.

I), rolam, Linn., the Flying Lizard. It is the/), major of Lamarck, 

 O. viridit of Daudin, 1). liowonienit of Lesson, and the D. Datidini of 

 iJnmc'ril. The scales of the back are nither broad, generally smooth ; of 



the throat granular, of the same size ; the lateral pouches of the males 

 moderate, rounded at the end, covered with ovate keeled scales ; the

 marbled with black, sometimes forming four or five oblique black 

 bands near the outer edge : the sides with a series of large broad 

 keeled scales.
