in places is coarse and resembles the preceding. It is very hard and 

 contains few fossils. Edriocrinus pocilliformis Hall 

 rand Leptaena rhomboidalis (Wilckens) were the only 

 species identified 3 feet 



L5b Shaly, rather friable, finely grained limestone. Exceedingly 

 fossiliferous 9 inches 



From here the following fossils were obtained :

Spirifer concinnus is in places so abundant that it makes 

 up almost the entire rock mass. 



L5C Limestone similar to L5a, usually in one bed. It is very 

 hard and contains few fossils. The only species identified were 

 Edriocrinus sacculus Hall r and Leptaena rhom- 

 boidalis (Wilckens) c 2 feet 



L6 Finely grained, bluish gray limestone. At the base and in the 

 middle are 4 inch friable, shaly bands similar to L5b and as we 

 would expect, since the fossils are fairly abundant throughout the 

 entire bed, many forms are similar to those in L5b, yet there is a 

 great decrease in the abundance of Spirifer concinnus and 

 an entire absence of Nucleospira elegans and Edrio- 

 crinus pocilliformis which were abundant in the lower 

 bed. This is placed in the Becraft on account of the abundance of 

 Spirifer concinnus. The other abundant fossils also are 

 those which were specially noticeable in the Gypidula pseudogaleata 

 beds 8 feet
