at the old lead mills on the Esopus that bore the name 

 Glenerie. The basal conglomerate he termed the Con- 

 nelly conglomerate from its typical exposure on the hill 

 above South Rondout (Connelly post-office). In Orange 

 county the beds representing Oriskany were divided 

 (Shimer '05) into Lower Oriskany (30 feet), the Dal- 

 manites dent at us zone with Helderbergian and Oriskany 

 species; and the Upper Oriskany (150 feet), the zone of 

 Spirifer murchinsoni. The Dalmanites dentatus zone 

 has been called the Port Jervis limestone (Chadwick '08). 

 The Glenerie limestone is dark blue in color, silicious, 

 and weathers to gray and finally buff colors. Chert bands 

 occur more or less frequently and in places it becomes 

 very shaly. The characteristic Oriskany fossils are the 

 brachiopods, among which are conspicuous forms as 

 Spirifer arenosus and Spirifer murchinsoni, Rensselaeria 

 ovoides, Hipparionyx proximus, Megalanteris ovalis, 

 Leptostrophia magnifica, Plethorhyncha barrandei, and P. 

 pleiophleura, Camarotoechia oblata, C. pleio pleura, Rhipi- 

 domella musculosa and smaller forms as Meristella lata, 

 Eatonia peculiaris and Leptocoelia flabellites. Gastro- 

 pods are represented by Diaphorostoma ventricosum }] 

 Platyceras nodosum, Cyrtolites expansus, Strophystylus 

 expansus; pelecypods by Pterinea textilis var. arenaria, 

 Pterinea gebhardi. 



The deposits of Oriskany age in southeastern New 

 York (Port Jervis region) are considered as represent- 

 ing a deep-water or calcareous phase of the shallow- 

 water, typical Oriskany sandstone. As mentioned above, 

 the lower beds (Port Jervis) or Dalmanites dentatus 

 zone, have a mingled Helderbergian and Oriskanian 

 fauna, and they carry besides the especially abundant 

 D. dentatus, the trilobite Homalonotus vanuxemi. The
