830 SYSTEMATIC SYNOPSIS OF FOSSIL BIBDS 



" In its main features, the present specimen resembles the skull of the Matitcc, more than 

 that of any existing birds. Other parts of the skeleton will doubtless show stUl stronger 

 reptilian characters. 



" In the matrix- attached to this skull, a single tooth was found, which most resembles the 

 teeth of birds, especially those of Ichthyornis. It is probable that Laopteryx possessed teeth, 

 and also biconcave vertebrae. 



" The specimen here described, and others ajjparently of the same species, were found in 

 the upper Jurassic of Wyoming Territory, in the horizon of the Atlantosaurus beds."
