Only known by a tarso-metatarsus, femur and tibio-tarsus from the Middle
Island, New Zealand. The bones at once noticeable by their great length,
and are more slender than the same bones in _D. maximus_. This form must
therefore, till further material comes to hand, be treated as a separate
species.
