 to 6-8in. Total length of the head, from 8m. to 7'8in. Length 

 of scapulo-coracoid, 7'5m. Length of ilium, 20in. to 19-5in. ;

Distrihution. — Found all down the east side of the South 

 Island from Motunau to Southland, but most common in 

 Otago. No. 1 is from Heathcote, near Christchurch ; No. 2 

 from a cave at Castle Rock, Southland (it is now in the pos- 

 session of Mr. Mitchell) ; No. 3 is the leg from the Knobby 

 Eanges, Otago, with integument attached ;'•' No. 4 from Tiger 

 Hill, Manuherikia, Otago. For the measurements of this last 

 specimen I am indebted to Mr. H. M. Platnauer, curator of 

 the York Museum. I am not aware of any bones having been 

 obtained from Maori cooking-places. 



This species is more robust than D. ingens and smaller than 

 D. robustus. 



Sub-Genus Tylopteeyx.I 



Top of the skull more or less elevated. Breadth of the 

 temporal fossse about two-thirds that of the orbits. Breadth 

 of the skull at the squamosals about 1"3 times the length to the 

 nasals. Length of the basi-sphenoid, from the basi-occipital 

 to the end of the rostrum, about two and three-quarter times 

 the breadth at the basi-pterygoid processes. Occipital condyle 

 hidden by the supra-occipital. Beak rather narrower and not 

 so obtuse at the tip as in Dinornis ; length of the premaxillse 

 to the maxillary suture about one and a quarter times the 

 breadth. Plate XV., fig. 2.
