Austroliasis amethystinus clarki (Barbour, 1914)
The type locality is the relatively isolated Murray Island in Torres Strait, which is in Australian territory and about midway between the Australian and New Guinean mainlands.
Snakes from this area share the same characteristics as specimens from southern New Guinea and north-east Australia, which McDowell (1975) found to be essentially similar in most respects. Australian snakes referred to as Austroliasis amethystinus kinghorni (Stull, 1932) are herein referred to this subspecies as a junior synonym.
There is some doubt as to the origins of the type specimen for Austroliasis amethystinus. If it is of the same race as the form herein designated as clarki then clarki itself will be a junior synonym and therefore an invalid name. Until this is properly established it is probably best to regard Australian and southern New Guinea specimens as being of the subspecies clarki.
