HuTTON. — On the Moas of the North Island. 547 



fig. A) of Anomalornis found in a cave at Waipu, north of 

 Auckland. The dimensions of these three bones are as fol- 

 lows : — 



No doubt the femur belonging to the leg from the Waipu 

 Cave would be larger, as its mid. width would be about 

 36mm. The tibia is specifically identical with that figured 

 by Owen, in 1844, as belonging to D. didifor^nis, but as that 

 name goes with the metatarsus, which belongs to a smaller 

 species, we fall back on the femur as giving the name. Mr. 

 Lydekker is of opinion that the tibia figured by Owen may 

 belong to A. dromaoides, but I think it is too large. No 

 doubt it belongs to one or other of these species. 



There is in the Canterbury Museum a pelvis from Pohui, 

 Hawke's Bay, presented by Mr. H. Hill, F.G.S., which I am 

 inclined to refer to this species. It is a typical Anovialornis 

 in shape, and has the following dimensions : Length of the 

 ilium, 355mm. ; length of pre-acetabular portion, 198mm ; 

 height of pre-acetabular portion of ilium, 83mm. ; width at 

 the antitrochanters, 160mm. The lower margin of the pos- 

 terior portion of the ilium descends as a sharp ridge. The 

 lower surfaces of the centra of the three pre-sacral vertebras 

 are hollowed longitudinally.

The type is a metatarsus from Poverty Bay, which (from 



the figure) has the follovv'ing dimensions : Length : 173 mm. ; 



prox. width, 55ram. ; mid. width, 31mm. ; distal width, 



76mm. In the Canterbury Museum there is a set of the 



three bones of the leg from a cave near Whangarei, the 



Not Meionornis didiformis, Haast, which is M. didinus.
