24 KENTUCKY GEOLOGICAL SURVEY. 



Fragments of Tri nucleus concentric us are rather common and 

 those of Asaphus glgas very common. 

 The bryozoa include the following: 



Aspidopora calynda (James). 



Comtellaria fischeri Ulrich. 



Comtellaria emaciata Ulrich and Bassler. 



Crepipwa spatiosa Ulrich. 



Eridotrypa briarens (Nicholson). 

 Eridotrypa miitabilis Ulrich. 

 Eschar opora ponder osa Ulrich. 



Eeterotypa parmilipora Ulrich and Bassler. 



Homotrypella norwoodi n. sp. 



Peronopora miller i n. sp. 



Of these Eridotrypa briareus is very common and a charac- 

 teristic speciesi 



The principal localities where exposures were examined were 

 Lexington ( cut on L. & E. R. R. ) , Winchester ( several railroad 

 cuts, showing from 30 to 40 feet vertically) ; a small, abandoned 

 quarry on Big Stoner Creek, near the Wmchester~Mt. Sterling 

 pike; several railroad cuts on the L. & N., between Pleasant 

 Valley and Park's Ferry station; Lair station (railroad cuts) ; 

 Cynthiana; Boyd's station; Falmouth (several small quarries 

 and other exposures) ; Moscow (quarries for several miles along 

 the Kentucky bank of the Ohio river) ; Point Pleasant, Ohio (sev- 

 eral quarries) ; and Covington. The abandoned quarry on Indian 

 Creek, a short distance east of Point Pleasant, proved the best 

 collecting ground for fossils. One-quarter mile west of Point 

 Pleasant is a ravine which gives a complete measurable sec- 

 tion of the Point Pleasant beds, though the contact between 

 the Lexington and the Winchester is concealed. The section 

 here gives the thickness of the Winchester as about 60 feet, its 

 base being taken at 60 feet above low water. At Covington and 

 Ludlow the top of the Winchester is about 50 feet above low 

 water mark.
