Some wise men have told us that the common green lizard, the moko kakariki (Naultinus elegans) did not originate on earth, it just appeared from space. This looks like an offshoot of the myth concerning flying lizards. The Tuhoe folk have explained to me that the tree lizard develops from a kind of iro (maggot or worm) that is found in the nest of the tihe bird (Pogonornis cincta), while the iro from which the koeau species of lizard is developed is found in the nests of the kaka (Nestor meridionalis), and this iro is light-coloured. This koeau is said to be a species of lizard that grows to about the size of a young tuatara, a statement that does not tell us much. The name resembles kaweau, said to be another name for the tuatara; the koeau is said to be of a reddish colour, and to see one is ominous of coming evil and of death. This fact was proved to my satisfaction by my informant, who said: "Te Rangiua once saw a koeau, and now all his elders are dead." Some of the Tuhoe natives maintained that the koeau and tuatara are two distinct species. Bay of Plenty natives tell us that the tuatara on the Rurima islets develops from iro seen in nests of the kuia or petrel. The Tuhoe folk say that the cuckoo is in some way the offspring of the tree lizard.
