The student familiar with the western Portage or Buchiola 

 retrostriata 1 fauna will at once recognize in this faunule a repre- 

 sentative of that fauna. Its occurrence at a definite horizon in 

 Virginia and Pennsylvania has been previously noted by the 

 author. 2 Clarke 3 and Swartz 4 have recognized the same fauna 

 in western Maryland. It should be noted here that the Buchiola 

 retrostriata (G. speciosa) fauna listed by the author from the 

 White Sulphur Springs, Virginia, 5 section is not the faunal equiva- 

 lent of the B. retrostriata (G. speciosa) fauna of Williams, 6 but 

 comprises only the upper portion of Williams' fauna. As the 

 term is used by Professor Williams in Bulletin 244 it includes at 

 least three distinct faunas, each of which has a fairly definite posi- 

 tion in the sections. The writer's past and present usage makes it 

 include only the latest of these three — the Portage — thus making 

 it synonymous with the western Portage or Naples fauna of New 

 York. The recorded range of this species makes it permissible 

 to use the name in Professor Williams' comprehensive manner if 

 it is desirable to consider these several faunas collectively. But 

 the writer prefers the more restricted usage adopted by Professor 

 Williams in an earlier paper, 7 according to which it includes only 

 the western phase of the Portage fauna. The Portage fauna 

 appears to characterize about 600 feet of the Mountain Grove 

 section. Although the section is mostly exposed and the order 

 of succession of the different parts is clear, the local buckling of 



1 This fauna has also been called the Manticoceras intumescence fauna and Naples 

 fauna in New York.
