The three foUoivinr/ species, in those cases where it is Jcnotun, differ 

 from the iyjrical forms 0/ Anomalopteryx by the relatively larger 

 shull, in which the temporal fossa is only separated from the occiput 

 hi/ a narroiv ridge, the occipital ttdjercle is nmch less developed, and 

 the anterior process of the quadrate longer. It is therefore not 

 improbable that they shonld be regarded as representing a distinct 

 genus, in which event the name Cela shoidd be adopted.

Founded upon the entire skeleton, in which the tarso-metatarsus 

 is somewhat smaller than the type of A. didiformis, but has the 

 same relative proportions. The skull is of the relatively large size 

 of that of A. didina, but the hallux is proportionatelj' smaller. The 

 skull is characterized by the temporal fossfe being separated from 

 the occiput merely by a sharp ridge, instead of tlie flat space found 

 in A. didiformis. The tarso-metatarsus alone will scarcely serve to 

 distinguish this species from A. didiformis, although there is such a 

 wide difference between the skulls.

The limb-bones are rather larger and relatively more slender than 

 those of A. curia, and thus present the same relative proportions as 

 in the much smaller A. oweni. The present form (apart from its
