_Pachyornis immanis_ Lydekker, Cat. Foss. Birds Brit. Mus., p. 343
(1891).
This is the most bulky and largest member of the genus, and also of all
_Dinornithidae_. Its living parallel to-day is _Casuarius philipi_
Rothschild, which, though by no means the tallest species of _Casuarius_,
is the most bulky, and has the shortest and stoutest legs--the
tarso-metatarsus is specially short and stout.
The type tarso-metatarsus measures 228 mm. = 8.9 inches, and in width
(shaft) 84 mm. = 3.3 inches, while the type tarso-metatarsus of
_elephantopus_ measures 239 mm. = 9.4 inches and 65 mm. = 2.55 inches.
The skull is much more depressed than in _elephantopus_ and with deeper
temporal fossae and a shorter post orbital region.
Type: No. A168 British Museum.
Habitat: Middle Island, New Zealand.
