EUKYAPTEHYX CRASSA. 



Dinornis crassus, Oweu. 



E^neus crassus, Lydekker. 



Syornis crassus, Button (not Palapteryx crassus, Haast). 



The number of leg-bones measured was — metatarsi, 108; 

 tibisB, 99; femora, 101. This species, although so difficult to 

 disentangle from M. casuarinus, is distinguished by its greater 

 robustness, and by having a shorter tibia but longer femur. 

 Here again the diagrams show only one point of concentration 

 for each bone, so that there could not have been a difference 

 in size between the sexes. 



The width of the sternum below the costal border is about 

 o-8in., and the length of the body is oin. The length of the 

 pelvis is 16in. to 17"oin., and its width at the antitrochanters 

 is 8-5in. to 9in. 



EURYAPTERYX PONDEROSA. 



Palapteryx elephantopus (part), Haast. 

 Emeus, sp. a, Lydekker. 



Euryapteryx ponderosa and E. elephantopus (part), 

 Hutton. 



The number of leg-bones measured was — metatarsi, 25 ; 

 tibiae, 15 ; femora, 23. The width of the sternum below the 

 costal border is Gin. to 6-5in., and the length of the body 4-5in. 

 to 4-7in. The length of the pelvis is 18in. to 19in., and its 

 width at the antitrochanters is 10-5in. to ll-Sin. ; the depth 

 of the antacetabular part of the ilium is 5in. to Gin. 



The diagrams show a single point of concentration in the 

 metatarsi and tibiae, but the femora are diffused. The leg- 

 bones differ from those of E. crassa more in thickness than in 

 length, but as a species it is well marked off, especially by 

 its relatively longer and stouter tibia. 



Euryapteryx gravis. 



Dinornis gravis, Owen. 



Euryapteryx gravis, Haast. 



Emeus gravipes, Lydekker. 



Eurya2)teryx gravis and E. compacta, Hutton. 



The number of leg-bones measured was — metatarsi, 23 ; 

 tibiae, 12; femora, 16. The width of the sternum below the 

 costal border is about 5in., and the length of the body 4in. 

 The length of the ^jeto/s is about 14-5in., and its width at the 

 antitrochanters is 7in. to 8in. 



In this species none of the bones show a decided concentra- 

 tion. It is very closely allied to E. crassa, the limb-bones 

 having the same proportionate lengths, but it is smaller,
