refer them to Anomalopteryx. The species makes a near 

 approach to the specimen No. 2 of .4. didiformis from Takaka, 

 in the Nelson Museum ; but it is smaller, and I think it 

 advisable to keep it separate from that species, partly on this 

 account and partly because of its far greater age. It is, no 

 doubt, the ancestor of A. didiformis. 



Genus CELA. 



Dinornis (part) and Palapteryx (part) of Owen ; Cela of 

 Eeichenbach, not of Moehring (1752), which is a synonym of 

 Casuarinus. 



Shell convex, the temporal fossse very large. Breadth at 

 the squamosals, about 1-6 or 1-7 times the height at the basi- 

 temporal. Length from the supra-occipital to the nasals 

 rather less than the breadth at the squamosals ; occipital 

 condyle hidden by the supra-occipital. Eidge between temporal 

 fossae and supra-occipital narrow. Beak short, slightly com- 

 pressed and rounded at the tip (but more pointed than in 

 Anomaloptcryx) ; the length of the premaxillae to the maxillary 

 suture about one and a half times the breadth. Lower 

 mandible nearly straight, and rather slighter than ii\ Anomalo- 

 ptcryx. Plate XVI., fig. 5. 



Sternum with the coracoid pits faintly indicated or alto- 

 gether absent ; length of the body less than the breadth ; 

 costal processes well developed ; lateral processes diverging 

 at diiferent angles. 



Pelvis rather broader, in proportion, than in Dinornis, and 

 the acetabula set more forward. The greatest breadth at the 

 anti-trochanters is 1-1 times the length of the pre- acetabular 

 portion of the ilia; the length of the ilium is from 2-4 to 2-5 

 times the length of the pre-acetabular portion. Metatarsus 

 shorter than the femur ; its length between 1-7 and 2-25 times 

 the girth at the middle of the shaft. Tibia about 2-2 times 

 the length of the metatarsus ; its length between 3'8 and 4-4 

 times the girth of the shaft. Fevmr with a length of 1-2 times 

 that of the metatarsus, and between 1-8 and 2*4 times the 

 girth of the shaft. The presence of a hind-toe has not been 

 proved. 



This genus contains the smallest species of moa, and is 

 confined to the North Island. 



Cela geranoid.es. 



Palapteryx geranoides, Owen, Trans. Zool. Soc, vol. iii., 

 p. 345 (1848) ; metatarsus and cranium as of dro7nioides, 

 not that of geranoides. 

 Figxircs. — Metatarsus, Ext. Birds of N.Z., pi. Ixx., figs. 5, 6; 

 cranium, pi. xxxi., figs. 4, 5, and pi. xlvi., figs. 1-3.
