Station 8B. — The following species were obtained from the 

 three and one-half feet of Black shale outcropping above the 

 limestone: 



Chonetes lepidiis a, Lingula spatulata a, Tcntaciilites fissiirella a. 



Station yA. — At the wagon bridge over the Muscatatuck one 

 mile below Crothersville the New Albany shale outcrops in the 

 bed of the stream, and Lingjila spatulata was found here 

 abundantly. 



Station jB. — Just below the bridge the Rockford limestone is 

 well exposed above the shale. It has here a thickness of five 

 feet, and afforded the following fossils: 



Anibocirlia gr'cgaria a, Athyris nov. sp., Chonetes genicidatus 

 White? a, Chonetes illinoisensis Win. c, Chonetes logani N. and P?

Five or six miles west of the last station the flat country, which 

 is underlaid by the Black shale and Rockford limestone, gives 

 way to the belt of knobs, which is here about twenty miles wide. 



Station 22 A. — At Low Gap ridge, near Lesterville, Washing- 

 ton county, fossils were found abundantly in the Riverside sand- 

 stone. At the "gap," which is about one mile north of the 

 school house, the following fossils were obtained: 



Camarotcechia sappho c, Chonetes logani a, Derbya kcoktik c, 

 Myalina keokiik c, Orthothetes crenistria f r, Plenrodiflyo7i prob- 

 Icmaticiim r, Productus neivberryi a, Prodiictus semireticulatus c, 

 Spirifer keokjck r, Syringothyris texta a, Tentaculites sp. r. 



Station 22B. — A quarter of a mile s. E. of the school hou.se on 

 Low Gap ridge some of the strata exposed at the roadside are 

 very fos.siliferous and furnished the following species:
