Pleiirophorus occidentalis M. & H. (aa). Many of the specimens are 

 external impressions, showing only the concentric lines ; one shows radiating 

 lines somewhat indistinctly and there are a number of internal impressions 

 which show very clearly the furrow made by the interior ridge. 



Myalina perattenuata M. & H. (a). 



Aclis Swalloviana (Geinitz) M. & H. (?) (rr). 



The yellow shales above the quarr}' stone are quite fossil- 

 iferous, No. lO especially. From these shales of Nos. 8 and 

 10 the following species were collected, the larger number, 

 however, coming from No. lO: 



Chojtetes granulifera Owen (aa) 



Chonetes Icsvis 'Keye.s={Chottetes glabra Geinitz) (c). Some of the speci- 

 mens are worn and show the radiating fibrous shell structure. 



Hiistcdia mormonii (Marcou) H. & C. (c). 



Sfiirifer {Aiartiiiia^ planoconvexns Shum. (aa). 



Spirifer cavie7-atus Morton (c). 



Spiriferi7ia ketittickensis Shum. (rr). 



Athyris [Seniifiicla) subtilita (Hall) Newb. 



Productus longispiiius Sowb.=(/'. spleiidens N. & P.)(r). 



Prodiictns cora d'Orbigny (c). 



Productus iiebrascensis Owen (rr). 



Productus semireticulatis (Martin) de Kon. (c). 



Productus syminetrictis McChesney (rr). 



Enteletes hemiplicatus {Yi-dXX) H. & C. ={SyntreIasma hemiplicatus (Hall) 

 Meek) (rr). 



Orthis carbonaria Swallow (?) (rr). Small specimen that seems to be 

 Orthis instead of Enteletes. 



Derbya crassa (M. & H.) H. & C. (rr).

Spirifer cameratiis Morton as well as numerous other Upper 

 Coal Measure shells are common in these upper yellow shales. 

 The faunal and lithologic characters of the section agree 

 closely with those of the Wabaunsee formation, to which it is 

 referred. Inasmuch as the rocks of this section are still his/her than
