Anomalornis is shown by the compressed centrum of the 

 anterior vertebra, and by its anterior pneumatic foramina 

 not descending below the rib-facet. The lower surfaces of 

 the centra of the three pre-sacral vertebrae are hollowed 

 longitudinally, as in the last species.

The type skeleton is in the Auckland Museum. 



The following are the measurements of the largest and 

 smallest of the leg-bones in the Canterbury Museum — the 

 smallest are rather larger than the types : — 



The femur has not the characters of the typical Anomal- 

 ornis, but is short and straight, with a rather deep popliteal 

 depression. The tibia has the distal extremity much expanded 

 inwards, as in ^. parvus. The metatarsus has deep lateral 

 pits on the middle trochlea, and generally on the anterior 

 surface at its base. 



The skull is very like that of A. didiformis, but is rather 

 smaller. The lacerate fossa is distinct from the optic foramen, 

 and there appears to have been a pre-sphenoidal shelf below 

 the optic foramen ; but this part of the skull is much damaged. 

 The width at the squamosals is 62mm. ; width at the temporal 

 fossae, 42mm. ; and the distance between the temporal ridges 

 is 29mm. The height of the cranium is 33mm. Distance 

 between optic foramina, 6mm. ; length of body of pre-maxilla, 

 20mm. ; width of the same, 18mm. ; greatest height of the 

 mandible, 14mm. ; length of mandibular symphysis, 6mra. ; 

 width of the same, 8mm. 



The width of the pelvis at the antitrochanters is (from the 

 figure) 102mm. The whole of the posterior portion is absent,
