446 DESCEIPTIVE GEOLOGY. 



and Waverly types have been obtained by our parties, and, since the com- 

 •pletion of our field-work, by Mr. J. E. Clayton. The vertical range of 

 the fossils obtained from this canon, which have all a Sub-Carboniferous or 

 Waverly aspect, shows a much greater development of these beds in the 

 Oquirrh Mountains than in the Wahsatch. From the westerly-dipping beds 

 near the mouth of the canon, in a blue limestone, were obtained the follow- 

 ing Waverly forms : 



Streptorhjnclms wflatus.' 



StropJiomena rJiomboidalis/ 

 Spirifer alba-pinensis. 

 Spirifer centronatus. 

 Rliynclionella pmtulosa. 

 ■ Euomphalus UtaJiensis/ 

 Euomphalus (StraparoUus) OpMrensis. 

 MicJielina, sp.? 

 Zaplirentls, sp.? 



By Mr. J. E. Clayton, from the ridge above, between Dry Cafion and 



East Cafion, in a close-grained black limestone, were obtained some of the 



same species, and: 



Proctus 2>6f0ccidens. 



Ortliis resttpinata. 



JEnomphalus latus var. laxns. 



From the northern side of Dry Canon, at a horizon, according to Mr. 

 Clayton, about 1,200 feet higher, he obtained: 



Trematopora. 



Fenestella. 



Polypora. 



While farther to the north, on the ridge toward Soldier Canon, and 

 still higher geologically, he found: 



Productus Icovicostus, 



Productus elegans, 



Productus semireticidatus, 



Productus Flemingi var. Burlingtonensis,
