LOWER CARBONIFEROUS FOSSILS. 489 



lington, Iowa, which have been referred to the same age." The following- 

 species are described as "Fossils of the Waverly group:" Michelina sp., 

 Streptorhynclius equivalvis, S. inflatus, Strophomena rhomboidalis, Chonetes 

 loganensis, Spirifera centronata, 8. alba-pinensis, Atliyris clayioni, A. planosul- 

 cata (?), Bhynchonellapustulosa (?), Terebrahda utah, Euomphalus (Straparollus) 

 utahensis, E. laxus, E. (Straparollus) ophirensis, Proetus peroccidens, P. 

 loganensis. The following may be mentioned as identical or cognate forms 

 occurring in the Madison limestone: Michelinia placenta (probably the same 

 as Michelinia sp. of Hall and Whitfield's report), Orthothetes incequalis (the 

 same as Streptorhynclius equivalvis), Leptcena rhomboidalis, Chonetes loganensis, 

 Spirifer centronatus (S. alba-pinensis seems to be only an insignificant varia- 

 tion from this form), Martinia rostrata n. sp. (the same as Atliyris planosid- 

 cata (?) of Hall and Whitfield), Camarotcechia metallica (the same form which 

 Hall and Whitfield identify as Bhynchonella pustulosa (?) ), Bielasma utah, 

 Straparollus utahensis, Proetus peroccidens, and P. loganensis. Of the forms 

 grouped under the heading "Fossils of the Lower Carboniferous" (p. 265), 

 Productus semireticidatus, P. Icevicosta, and Spirifera setigera (probably the 

 form recognized below as Iieticularia cooperensis var.) are found in the 

 Madison limestone. 



Meek' cites a fauna from various localities in Montana and one in Idaho 

 which is probably identical with that of the Madison limestone. The lists 

 which accompany this notice are of a preliminary character, and but few 

 species are identified specifically. Still, the genera involved, together with 

 such brief descriptions as are appended, as well as the close relation geo- 

 graphically of his localities to the Yellowstone National Park, render it 

 probable that he was dealing with the Madison limestone fauna. Meek 

 expresses himself as being impressed with the similarity of its general facies 

 to that of the Waverly group of Olii<>. 



The fauna! lists given by Peale 2 constitute essentially the same fauna 



the Bedford shale and ascending to its latest stratum, is undoubtedly Carboniferous. Tho fauna of 

 the Cuyahoga shale, using the term to include the outcrops at Lodi, Medina, Bagdad, Weymouth, and 

 the lower ( ?) beds at Richfield, which Herriek wishes to refer to the Devonian, is certainly the same 

 as that of the Chouteau limestone, which Meek includes as typical ir his description of the Kinderhook 

 period (Am. .Jour. Sci. (2), Vol. XXXII, 1861. pp. 169 et seq., 288). Above the Cuyahoga shale follow 

 representatives of the Burlington and Keokuk horizons. 



It is probably that portion of the Waverly faunas which is found in the Cuyahoga shale that 

 Hall and Whitfield have in mind in this reference, as they mention the yellow sandstones of Burling- 

 ton, which, with the Chouteau limestone, are supposed to be typical Kinderhook.
