The brown four-fingered skink is one of the commonest lizards encountered in new Guinea and is relatively common in all habitats on Karkar Island. The presence of four fingers, on the forefeet, is a derived characteristic demonstrating that Carlia is an advanced genus. Reduction and loss of digits and limbs is considered an evolutionary advancement within all lizard groups so four fingers is more advanced than five in skinks. This is a highly active diurnal skink which is also quite variable in pattern. Eventually it may be determined that more than one species is represented in the taxa.
