13. Dark gray, thin bedded, pure limestone 

 which weathers so as to show bands about an inch 

 in width. Bottom foot shaly. Fossils not com- 

 mon. The Rafinisqitinas found here are a small 

 but strongly marked variety, never exceeding three- 

 eighths of an inch in width. This variety occurs 

 also in C 10, where it is again associated with Cam- 

 arella longirostris, C. varians and Triplecia gracilis, 

 which are the most common species of the two 

 zones. 5 ft.
