CLASSIFICATION, AND PHYLOGENT OF THE DINOENITHID^. 375 



2. DmoENis ROBUSTUS, Owen. 



a. The skull belonging to the very fine individual skeleton found at Tiger Hill, Otago, 



and novp in the Museum of the Philosophical Society, York. 



This specimen is referred by Hutton to his I), potens, but I am more than 

 doubtful whether the distinction from robustus can be maintained, and prefer to 

 place it in the present species. 



b. The skull belonging to an individual skeleton found at Highley Hill, Otago, the 



property of Dr. T. M. Hocken. (Otago University Museum.) 



c. An imperfect and partly restored skull from Hamilton Swamp, Otago. (Otago Univ. 



Mus.) 



d. Mandible belonging to an individual skeleton found at Shag Valley, Otago. (Otago 



Univ. Mus.) 



e. Associated premaxillse, maxillo-jugal arch, quadrate, and mandible from Maun- 



gatua, Otago. (Otago Univ. Mus.) 

 /. A cranium from Enfield, Otago. (Dr. H. O. Forbes's collection.) 



This species is figured by Owen, Trans. Zool. Soc. vol. v. pis. liii. & liv. (Ext. 

 Birds of N. Z. pis. Ixii. & Ixiii.). 



3. DmoRNis TOKOSUS, Hutton. 



a. Skull belonging to a nearly perfect skeleton, the type of the species, found in the 



Takaka district. Nelson. (Mr. R. J. Kingsley's collection.) 



b. A nearly complete skull from Hamilton Swamp, (Otago Univ. Mus.) 



Captain Hutton considers that this skull is probably referable to B. struthioides, 

 but I can see no differences of any importance between it and the previous 

 specimen. 



This species is figured by Owen as I), ingens, Trans. Zool. Soc. vol. vii. pi. xv. 

 (Ext. Birds of N. Z. pi. Ixxxii.) ; also by Jaeger, as Palapteryx ingens, Reise der 

 Novara, Palaontologie, pis. xxv. & xxvi. 



4. DiNOKNis, species a. 



A damaged cranium of the same size as that of D. torosus, but differing from it in 

 having the temporal and lambdoidal ridges in contact. (Coll. H. O. Forbes.) 



Genus Pachtornis, Lydekker. 

 1. Pachyornis elephantopus, Owen. 



a. Six crania with separate premaxillse, maxillo-jugal arches, quadrates, and mandibles, 



from Enfield; in one instance (Plate LX. fig. 22) premaxillse and maxillo-jugal 

 arches were found which exactly fitted a cranium, and I have no doubt that they 

 belonged to the same individual. (Coll. H. O. Forbes & Cant. Mus.) 



b. Two crania, one with ("? associated) premaxillse and mandible ; locality unknown. 



(Coll. Mus. Wellington.) 



c. An imperfect cranium with associated premaxillse and mandible from Hamilton 



Swamp. (Otago Univ. Mus.)
