sils are usually abundant. The following list embraces the 

 species of bryozoa which have been recorded as occurring in. 

 (he Lexington in Kentucky: 



Callopora multitabulata (Ulrich). 



Constellaria teres Ulrich and Bassler. 



Cypliotrypa acervulosa (Ulrich). 



Cypliotrypa franJcfortensis Ulrich and Bassler. 



Dckayella foliacca Ulrich and Bassler. 



Delcayella trcn tonen sis ( Ulrich ) . 



Eridotrypa mutabilis Ulrich. 



Eridotrypa tren toncnsls ( Nicholson ) . 



Homotrypa callosa Ulrich. 



Homotrypclla granulijera (Ulrich). 



Mesotrypa angularis Ulrich and Bassler. 



Mesotrypa echinata Ulrich and Bassler. 



Mesotrypa quebecensis Ami. 



Monticulipora arborea Ulrich. 



Prasopora simulatri% Ulrich. 



The commonest and most easily recognizable forms are Pra- 

 sopora simiilatrix, Callopora multitabulata, and DeJcayella 

 trentonensis. 



Exposures of these beds were examined at Frankfort and sev- 

 eral other points in Franklin county^ at Lexington; at Lair, 

 Berry and Claysville in Harrison county; at Falmouth; and 

 along the Ohio river at Carntown, Moscow, and Point Pleasant. 

 The best section seen was at the road leading up from the Crow 

 Distillery, Squire P. O., five miles southeast of Frankfort. At 

 Lair the contact between the Lexington and the Winchester is 

 well shown. The upper beds (uppermost ?) are seen in the banks 

 of the Licking river and its branches at a number of points. 

 Those examined were at Claysville, Berry, and Falmouth. At 

 Carntown, Moscow and Point Pleasant, the Lexington extends 

 to about 40 or 50 feet above low water mark, but only a few feet 

 were exposed at each of these places, enough to prove that the 

 rocks are Lexington, though few fossils were to be had.
