sandstone and small gravel evidently of stream origin, near the middle

 spreading and moderately heavy. The sagittal crest is quite high and 

 thin. The superior wings of the occiput are also thin. The brain- 

 case is small ; the outward projecting zygomatic processes of the 

 squamosals shelf-like, and broad antero-posteriorly. The paroccipital
