posterus, Hall and Clarke; OrtJiis impressa, Hall, and Ormoid segments are 

 the most abundant species. The complete list is : 



1. Orthis impressa, Hall. (aa) 



Large form as reported by Clarke from southeast of Greene 

 (Thirteenth Annual Report, p. 543). 



2. P rod iictella lachrymosa (Con.), Hall. (aa) 



Probably some of these specimens should be cf. P. speciosa of 

 Ithaca, but the pustules are coarser than in this species. So 

 identified by Clarke in Thirteenth Annual Report, p. 543. 



3. Spi/rifer mucronatus (Con.), Bill., var. postern*, Hall and Clarke, (aa) 



Many of these specimens agree exactly with the figures of the 

 mucronate forms of this species. These are undoubtedly the 

 same as those from Chenango identified as Sp. mucronatus var. by 

 Professor II. S. Williams and figured in Bulletin Geological 

 Society of America Vol. L, pi. 12, f. 13.
