resembles that of Anomaloj^ti'ri/.v, but the pelvis is ranch wider and 

 approaches that oi Paclujornis. The tibio-tarsus and tarso-metatarsus 

 are relatively shorter and thicker than in Anonudopttriix, but less 

 stout than in Vachijornis ; the distal extremity of the tibio-tarsiis 

 not being inflected. A hallux is present. The length of the tarso- 

 metatarsus is considerably less than that of the femur, and than half 

 that of the tibio-tarsus, its width at the middle of the shaft being 

 rather more than one fourth of the length. The femur is relatively 

 shorter and more flattened from front to back in E. gravipes than 

 in the larger species of Anomaloptert/x, but that of E, crassus does 

 not present any well-marked generic featiu-es. In the relative 

 length of the neck the femur of E. gravipes is intermediate between 

 Dinoj'nis and Pach}jornis. The vertebriB are of the type of 

 Anomalopteryx. 



The species are larger than anj- forms of Anomalopteryx. 



As additional cranial characters it may be observed that the skull 

 usually has very broad and blunt paroccipital processes ; there is 

 no distinct supraoccipital prominence, and no well-marked depression 

 upon the frontal aspect of the squamosal above the head of the 

 quadrate ; the basioccipital tubercles are prominent, and give an 

 arched posterior profile to this bone. The quadrate is elongated, 

 with a long anterior bar ; and the cavity of the squamosal for the 

 reception of its head is inclined much more outwardly than in either 

 of the other genera.

The type species of Euryapteryx. 



The Dinornis gravis, Owen % having been founded upon a skull 

 indistinguishable from the one referred to E. crassvs, and which is 

 apparently too large for the limb-bones subsequently described under 

 the former name, it would seem that the one name is a synonym 

 of the other. Consequently the form represented by the limb-bones 

 appears to require a new name, unless the specific term r7icidcs be 

 adopted for this form. There is, however, no evidence whatever to
