Immediately above these beds appear 11 feet, 3 inches of chert 

 beds, followed by 18 feet, 7 inches of a fine quartz pebble conglom- 

 erate (=29 feet, 10 inches). Then comes in a silicious and quite fossil- 

 iferous limestone 5 feet, 6 inches in thickness (no. 29 of the section) 

 and over it about 36 feet of chert bands containing a few fossils. 

 The entire thickness of the deposits from the top of the Kingston 

 beds to the base of the Esopus shale is about 60 feet. 



The fauna of this part of the section is essentially contained in 

 the calcareous layer, and is the following: 



Dalmanites cf. stemmatus 

 Phacops logani 

 Proetus conradi 

 Tentaculites elongatus 

 Diaphorostoma ventricosum 

 D. desmatum 

 Cyrtolites sp.% 

 Platyceras tortuosum 

 Cryptonella fausta 

 Megalanteris ovalis 

 Camarotoecliia pliopleura 



Camarotoechia barrandii 

 Eatonia peculiaris 

 Meristella lentiformis 

 Spirifer murchisoni 

 Leptocoelia flabellites 

 Chonetes hudsonica 

 Chonostrophia complanata 

 Leptostrophia oriskaijia 

 Edriocrinus sacculus 

 Cladopora smicra 



All of these species with the exception of Edriocrinus sac- 

 culus are observed in the Becraf t mountain Oriskany fauna. No 

 species occur in the chert bands which are not represented here. 



At Gknerie, 7 miles north of Kingston, the same calcareous beds 

 of the Oriskany are finely fossiliferous, probably affording a more 

 complete representation of this fauna. The following are among the 

 species identified : 



Dalmanites cf. stemmatus 

 Phacops logani 

 Tentaculites elongatus 

 Diaphorostoma ventricosum 

 D. desmatum 

 Cyrtolites sp. n. 

 Platyceras gebhardi 

 P. reflexum 



Meristella lentiformis 



Spirifer arenosus 



S. murchisoni 



Trematospira sj). n. 



Anoplia nucleata 



Leptaena rhomboid alls, va/r. ventricoBa 



Leptostrophia magniiica 



L. oriskania
