Form. This species closely resembles Draco lineatus, Daudin, (Dra- 

 cunculus lineatus, Wiegmann,) from which it differs in the following 

 particulars. The adult male carries a very elongated, pointed gular 

 pouch, double the length of the head, and a slightly elevated cervical 

 crest, consisting of 6 to 8 pointed tubercular scales, and continued 

 along the anterior half of the back in the shape of a ridge composed 

 of a raised fold of the skin. The female has neither cervical crest nor 

 dorsal ridge, and her gular pouch is much reduced, its length being 

 about one half of the length of the head. Both sexes have the follow- 

 ing characters in common. From each side of the neck commences a 

 series of spinous scales, sometimes close together on one side, distant 

 on the other, which, increasing in size and becoming more distant, 

 continue along the side of the body, where they deviate outwards, 

 marking the origin of the wings, and again converge towards the 

 root of the tail, where they terminate. The scales of the back are 

 generally smooth, consisting of smaller polygonal, mixed with some 

 larger rhombic, indistinctly keeled, imbricate scales. In some indivi- 

 duals the latter are disposed so as to form a series on each side of the 

 dorsal spine. The supraorbital margin has from 3 to 4 large pointed 

 tubercles, of which but the one situated at the posterior angle appears 



* "Grey, black-spotted; wing's blackspotted ; throat grey; poucli of the male 

 elongate ; scales of the back rather unequal, rhombic, keeled ; of the sides rather 

 smaller ; sides with a series of large keeled scales ; ears rather sunk, with unequal flat 

 scales ; tail slender, with a central keel above, and 5 more small ones on the sides, base 

 dilated, with 5 nearly equi-distant equal keels above." {Catalogue of the Specimens of 

 Lizards, &c. p. 236.)
