Dr. von Haast (Sir Julius von Haast) took as his type of _Dinornis oweni_ the almost complete skeleton collected by Mr. Cheeseman in a cave at Patana, Whangarei, and now in the Auckland Museum. While referring my readers to the original diagnosis for the specific characters, I wish to specially draw attention to the fact that Dr. von Haast says that in the collections he examined, made by Mr. Thorne and Mr. Cheeseman, there are bones belonging to at least 20 skeletons of his _D. oweni_, and that some were even smaller than the type, and the only difference was the constant average difference due to sex. I draw special notice to this, as Captain Hutton has united this form with _curtus_, saying Haast's type is only a small individual of that species. The fact of bones of at least 20 different individuals, showing the same characters and the same differences from _curtus_, is quite sufficient evidence for me to consider Dr. von Haast's _D. oweni_ as a distinct species. I append measurements of the leg bones of the types of _Cela curtus_ and _C. oweni_:-- -------------+-------------------+----------------+--------------- | Tarso-metatarsus. | Tibio-tarsus. | Femur. -------------+-------------------+----------------+--------------- _Cela curtus_| 5.0 inches | 11.25 inches | 5.65 inches _Cela oweni_ | 4.4 " | 9.6 " | 6.5 " -------------+-------------------+----------------+--------------- Locality: Whangarei. Habitat: North Island, New Zealand. CELA GERANOIDES (OWEN.) _Palapteryx geranoides_ Owen, Trans. Zool. Soc. III, p. 345 (1848). _Cela geranoides_ Hutton, Trans. N.Z. Inst. XXIV, p. 126 (1892). This species is confined to the North Island. The type came from Waingongoro. It is most commonly found in the South of the Island. Habitat: North Island, New Zealand. {207} CELA RHEIDES (OWEN). _Dinornis rheides_ Owen, Trans. Zool. Soc. IV, p. 8 (1850--partim). _Syornis rheides_ Hutton, Trans. N.Z. Inst. XXIV, p. 131 (1892). This is a very difficult form to consider, as the type bones consisted of those of three different forms. Whether Professor Owen, were he now alive, would concur in Captain Hutton's treatment is very questionable, and I doubt if it ought not to be united to _Emeus crassus_, while Haast united it to _P. gravis_. I have kept it separate as no bones of a single individual united are known, and it might prove sufficiently distinct if a good skeleton were obtained. The type bones were sent from Waikawaite, Middle Island, by Colonel Wakefield, in 1849. Habitat: Middle Island, New Zealand. CELA CASUARINUS (OWEN). _Dinornis casuarinus_ Owen, Trans. Zool. Soc.
