BEEDE : FAUNAL STUDIES, II. 177 



Bennett collection contains the following specimens taken from 

 this thin limestone : 



Fusulina secalica ( Say) Fischer. 



Meekella striaticostata (Cox) White and St. John. 



Productus semireticulatus ( Martin) d'Orbigny. 



Bellerophon, sp. 



31. Chocolate Limestone. This name, as well as the one 

 preceding and the one following, are used merely for conven- 

 ience here, as they have been used before for the designation of 

 these rocks, knowing that with further study and careful tracing 

 they will be found to be the equivalents of similar rocks on the 

 Neosho river section. This limestone is buff brown in color, 

 varying from seven to ten feet in thickness, composed princi- 

 pally of two layers of massive stone, the upper of which is com- 

 posed largely of the large variety of Fusulina secalica. In the 

 Kansas river region it always forms high escarpments with 

 rocky edges. It is not rich in any fossils except the Fusulinas. 



Fusulina secalica (Say). 



Lophophyllum profundum{ Milne-Edwards and Haime) Foerste. 



Chonetes granulifer Owen. 



Enteletes hemiplicata (Hall) Hall and Clarke. 



Meekella striaticostata (Cox) White and St. John. 



Productus cora d'Orbigny. 



Productus nebraskensis Owen. 



Seminula argentia (Shepard) Hall. 



32. Shales and sandstones shown near Dover, eighty-five 

 feet in thickness, varying from light yellow to brownish red. 



33. Dover Limestone. A limestone about four feet in 

 thickness and of grayish color. 



34. Somewhere from forty to seventy feet of shales, with oc- 

 casional thin limestones with Myalina perattenuata. 



35. Ten to twelve inches of very fossiliferous limestone in 

 thin layers. Numbers 32 to 35 are as exposed on Mission creek 

 and its tributaries near Dover. Number 35 is shown in ravines 

 southwest of Dover, in the high region east and south of Mis- 

 sion creek.
