Observations recorded by Messrs. Swallow and Hawn 

 and Meek and Hayden in northern Kansas, and others made 

 by the writer in southern Kansas, indicate that Athyru 

 suhtilita and several other Carboniferous species of fossils 

 may occasionally range up into the basal part of the Geuda; 

 but the fossils thus referred to should perhaps be regarded 

 as more or less varietal representatives of their types. 



Several years ago, Mr. E. F. Osborne informed the 

 writer of an early discovery of reptilian footprints near 

 Salina in rocks which must be referred to this division. 

 About four miles east of Salina, at a point about half a mile 

 south of the Smoky Hill river and west of north of Iron 

 mound, is an abandoned quarry. The upper stratum is a 

 ten inch ledge of so-called "bastard limestone" that was 

 used by the settlers in the earlier days of Salina's history 

 for walling wells, etc.f- It is upon this stratum that the 

 footprints were found. It is possible that the reptilian 

 footprints discovered many years ago by Prof. Mudge on 

 rocks of the bluffs of the Republican river in northern Kan- 

 sas should also be referred to this formation. 



Frairments of a charcoal-like sort of fossil wood that oc- 

 cur in the salt mines at Kingman, in rock-salt-bearing shale

tWells on the old Osborne place and on the Snyder place were 

 walled with this stone, and some of the stone i)robably remains in foun- 

 dations of old buildings in the vicinity.
