Prodtictus ivesi Newberry c 



Farther down the valley the gray, cross-bedded Coconino sandstone 

 conies in beneath the limestone of locality 7, which in turn rests npon the 

 red shales of the Snpai formation. Localities 7, 6, and 5 are respectively 

 the lower, middle, and npper Kaibab, 1 to 4 the lowest Moenkopi. 



From the upper Kaibab, at the eastern foot of Moimt Trumbull, were 

 collected :

 underlain by red, gypsiferous shales.
