Haast. — On the Extinct Genus Harpagornis. 75 



remarkable development of all the principal features to be observed in the 

 pelvis of the smaller recent Diurnal Raptores. 



Finally, I wish to observe that the pelvis of Harpagornis moorei, from 

 Otago, has still some of its integuments and ligaments attached, of which the 

 lining membrane on the walls of the acetabulum are best preserved ; whereas 

 the more fragmentary bone of If. assimilis is in the semi-fossil cocdition in 

 which all the bones from the remarkable turbary deposits of Glenmark are 

 usually found. 



Since my former paper a second ungual phalanx has been obtained, which, 

 applying the same mode of measurement previously used, is 2 '75 inches long, 

 and has a circumference of 2*92 inches at its proximal end. It is the third 

 phalanx, and belongs to the second or inner toe of the right foot. 



Amongst the smaller bones lately excavated I found also the second 

 phalanx, with which that latter ungual phalanx articulates. 



The pachydermal character, even in these toe-bones, is well sustained, and 

 the form and peculiarities of the articular ends, and the large concavity behind 

 and below the trochlear joints of the distal end, are developed in a sti-iking 

 degree. 



Of Harpagornis assimilis we possess, as previously observed, several 

 phalanges.
