CARBONIFEROUS AND PERMIAN FORMA TIONS I 5 I 



a practically complete list of the fossils of that region. No 

 attempt was made to duplicate his work, and only the few species 

 noted below were collected : 



Productus {Marginifera) sp/endens Nor. & Pratt (c). Meek referred 

 this to P. longispinus Sow. with which identification Keyes agrees, and prob- 

 ably this is correct. 



Productus costatus Sowb. (rr). 



Producius punctatus (Martin) Sowb. (rr). 



Spirifer cameratus Morton (?) (rr). Imperfectly preserved specimen. 



Chonetes grcutulifera Owen (rr). 



E?iieletes hemipiicatus (Hall) H. & C. (rr). Formerly Syntrilasma hemi- 

 plicatiis (Hall) Meek & Worthen. 



Edmondia sp. (rr). The specimen has rather high beak but is narrower 

 than the figures compared, with quite sharp concentric lines. 



Macrocheilus mtercalaris M. & W. (rr) v2.r. pulchellus M. & W. changed 

 by Keyes to Sphcrrodoma mcdialis (M. & W.) Keyes. 



Fusulina cylindrica Fischer (c). 



Cy there nebrascensis Geinitz (?) (c). 



Meek found Spirifer cameratus in the limestone above the 

 coal associated with plenty of other fossils characteristic of the 

 Upper Coal Measures, so that it is clearly shown by the stratig- 

 raphy and paleontology that all of the Palaeozoic rocks in the 

 vicinity of Nebraska City belong in the Upper Coal Measures 

 (Missourian) instead of in the Dyas (Permian) as claimed by 

 Marcou. The writer is not confident whether the Nebraska 

 City beds should be referred to the upper part of the Missouri 

 formation or to the Wabaunsee formation of the Missourian 

 series. However, the faunal and lithologic characters of the 

 beds near Nebraska City agree quite closely with those of the 

 lower half of the Wabaunsee formation as shown along the Kan- 

 sas River above Topeka, and so the writer refers them pro- 

 visionally to it. 



Dunbar.— TVx^ station on the B. & M. R. R. R. is eleven miles 

 west of Nebraska City and nearly 150 feet higher than the Mis- 

 souri River at that point. One mile south and one and one- 

 half miles east, or about two miles southeast of Dunbar, on the 

 south side of the B. & M. R. R. R., is the McCartney quarry.
