HuTTON. — On the Moas of Neiu Zealand. 



123 



breadth at the squamosals ; occipital condyle hidden by the 

 supra-occipital, but exposed laterally. Length of the basi- 

 sphenoid to the end of the rostrum about two and a half 

 times the breadth at the basi-pterygoid processes. The 

 maxillo-jugal bones curved, concave outwards. Temporal 

 fossae very broad, about equal to the orbits. Beak short, 

 slightly compressed, and rounded at the tip. Length of the 

 premaxillffi to the maxillary suture rather more than one and 

 a quarter times the breadth. Lower mandible strong and 

 nearly straight. Plate XV., fig. 4. 



Sternum with well-marked coracoid pits, the length of the 

 body equal to the breadth. Costal processes moderately 

 developed ; the lateral processes diverging at an angle of about 

 20° with the middle line ; the posterior median process long. 

 Breadth across the ends of the lateral processes, from 1-2 to 

 1-4 times the breadth of the body. Three pairs of sternal 

 ribs articulating with the sternum. 



Pelvis narrow, like that of Dinornis ; the greatest breadth 

 at the anti-trochanters is rather less than the length of the 

 pre-acetabular portion of the ilium. The position of the ace- 

 tabula varies; the length of the ilium being from 2 to 1-8 

 times the length of the pre-acetabular portion. Metatarsus 

 shorter than the femur; its length between 2 and 2-3 times 



the girth of the shaft. 



Tlhia between 2-1 and 2-2 times the 



length of the metatarsus ; its length between 4-2 and 5-1 times 

 the girth. Length of the femur 1-25 times that of the meta- 

 tarsus, and between 2 and 2-5 times the girth of the shaft. 

 A hind-toe was present.
