Tabular List of Species, with Distribution 



In the table showing the distribution of species the Kaibab and Moen- 

 kopi sections are each grouped separately. Only in section h were both 

 Moenkopi and Kaibab fossils collected from the same section; thus the 

 two fossils found here in the Moenkopi (Leda ohesa E, and Bakewellia 

 parva, c) are not listed in the table below. 



The following abbreviations are used: 



C = very common, c = common, r = rare, E = very rare. The names 

 of the lettered sections are given in the table of contents.
