A armata, Gray, 

 Body covered with small rough granular scales, larger scales 

 each terminating in a small spine. A vertebral crest, slightly 

 interrupted on the neck. Spines of crest long anteriorly, trian- 

 gular behind. A fold before each shoulder not extending across 

 the throat. Ventral scales keeled. The scales- in the preeanal 

 region larger than the ventrals. Tail slightly compressed. Scales 

 below strongly keeled, longer than broad, each terminating in a 

 small spine. Colour greenish brown with roundish light spots. 

 Five or six black lines radiate from the orbit over the lip. 



Length, body 5-50 ; tail 700 = 12-50 inches. 



Inhabits Tenasserim, Singapore, Pinang and Kochin China. 

 This genus is hardly represented in British India, save in 

 Tenasserim. I once, however, procured a lizard in Rangoon, with 

 an orange vertebral line, which I doubtfully referred to A capra 

 Gunther. 



TiARis, Gray. 



Back and sides covered with small imbricate scales with 

 scattered larger ones. No spine behind the superciliary margin. 

 Dorsal crest of non-united spines, A gular sack in males and 

 fold before the shoulder in both sexes. 



T. subcristata, Blyth. 



Coryphophylax Maximiliani Fitz. 

 Scales of the body very small, intermixed with some larger 

 ones. Some enlarged tubercles at the base of the tail. Subcaudals 

 in two rows very sharply keeled. Nuchal crest small save in 

 old males, in whom it is higher than the dorsal. Dorsal crest con- 

 tinued to the end of the tail which is considerably compressed. 

 Limbs and tail very long. Colour in adults uniform greenish with 

 some dark stripes in front of the shoulder. Males reticulated and 

 obliquely striped with dark brown on the sides, the light in" 

 terspaces variegated with yellow and red. Sometimes the whole 

 vertebral region purplish red. The gular sack is reticulated 

 with reddish yellow, and black. Numerous black streaks radiate
