Ctenophorus clayi, also known commonly as the black-collared dragon,[1] the black-shouldered ground-dragon, and Clay's dragon, is a species of lizard in the family Agamidae. The species is endemic to Australia.
The specific name, clayi, is in honor of Australian herpetologist Brian T. Clay (1950–2004).[2]
C. clayi occurs in red sand-ridges with spinifex in the central and western deserts of Australia, with an isolated population existing in North West Cape in Western Australia.[1]
