Doria's Forest Dragon

Doria's angle-headed lizard, or Peter's forest dragon, is an arboreal lizard in the family Agamidae. The account used here gives it as endemic to Borneo, so its Sumatran and Malaysian listings should be checked. It is usually green on top with dark and light flecks and an indistinct wavy grey pattern, and sometimes has large orange patches. The dewlap is yellow with greyish-blue stripes (Wikipedia, general species account).
