162 0. CO. Marsh— On a New sub-class of Fossil Birds. 
When the remains of this species were first described, the 
portions of lower jaws found with them were regarded by the 
writer as reptilian ;* the possibility of their forming part of the 
same skeleton, although considered at the time, was not deemed 
sufficiently strong to be placed on record. On subsequently 
removing the surrounding shale, the skull and additional por- 
tions of both jaws were brought to light, so that there cannot 
now be a reasonable doubt that all are parts of the same bird.
