Phoenix limestone, 300 ft. ; Tilden limestone lentil, 100 ft. ; Yampa 

 limestone, 300-400 ft. ; Highland Boy limestone, 400 ft. ; Commer- 

 cial limestone, 200 ft. ; Jordan limestone, 300 ft. ; Lenox limestone, 

 200 ft. ; Butterfield limestone, 300 ft. In the Wasatch and Uintah 

 Mountains, the Weber conglomerate of the same age, overlies the 

 upper Wasatch limestone which is Carbonic and is succeeded by 

 Permo-Carbonic shales and limestones. Both the Weber and 

 Bingham series have been correlated with the Hueconian of Texas, 

 and the Aubrey of northern Arizona. 



In Nevada, the White Pine shale possibly of lower Carbonic 

 age (with a fauna according to Girty like that of the Caney shales) 

 is succeeded by the Diamond Peak Quartzite, this by the " Lower 

 Coal Measure " limestone, this by Weber conglomerate and this by 

 the " Upper Coal Measure " beds. In the Canadian Rockies, the 

 Banjf limestone is in part at least of Carbonic age. Finally in 

 northern California, the lowest Carbonic beds are the Baird shales, 

 followed by the McCloud limestone which is correlated by J. P. 

 Smith with the entire Carbonic series of central Texas from the 

 Bend to the Cisco inclusive. The McCloud shales are correlated 

 with the Wichita-Albany beds or the Artinskian of Europe. 



Carbonic deposits are extensively developed in northwestern 

 America including Alaska. In the different Alaskan provinces, the 

 following formations have been assigned to the Carbonic (including 

 Permic and Mississippic). In western British Columbia and 

 Yukon territory : Cache Creek group, partly perhaps Devonic. In 

 southeastern Alaska, Ketchikan series, probably in part Triassic. 

 In Prince William Sound and lower Copper River basin: Chiti- 

 stO'ne limestone. In the upper Copper and the upper Tanana basin : 

 Mankomen group (Permic) Nabesna limestone, and Suslota lime- 

 stone. In northwestern Alaska: Lisburne, Stuver and Fickett 

 series, the first Permic, the last partly Devonic. 



In Nova Scotia and elsewhere in eastern Canada, the Coal 

 measure series (including the Permic), have been divided in de- 

 scending order into:*^ Cape John Sandstone; Pictou Freestone; 

 Smelt Brook shale; Merigomish limestone; New Glascow con- 

 glomerate; Coal measures or Stellarton formation; Westville beds 

 or Millstone grit; Hopewell sandstone and Windsor formation,
