The principal dimensions of this species can be got at with con- 

 siderable certainty. Although two of the wing-phalanges and the 

 bones of the foot are wanting, yet the relative proportions of those 

 present agree so closely with those of the corresponding bones in 

 Pteranodo7i, that there can be but little possibility of error in assum- 

 ing the same proportions for the missing ones. The position of the
