139 Devonian op Southern Indiana ii 



Statw7i iB. — At an old quarry on the south side of Sand creek 

 three-fourths of a mile above Kelt's mill about ei^ht feet of lime- 

 stone is exposed, containing an abundance of fossils. Those ob- 

 tained were: 



Oiiychodiis sigmoidesf , Pleurodiclyon problcmaticum, Polypora 

 sp?, Proetus canaliadatus f , Spiri/ei^ acumiiiafiis, Stropheodonta 

 deviissa, Stropheodonta peiplatia, Tcntaculites bclluhis. 



Spirifer anmiinatiis is the predominant species and is very abund- 

 ant here. 



Below the quarry a hard grey magnesian limestone, which is 

 probably of Niagara age, is exposed. No fossils were found in it. 



Statio7i I A. — At Kelt's Mill the broken dam gives access to 

 the Black Shale, which outcrops above it in the bed of the stream 

 and rises a few inches above the water level. The shale forms 

 the bed of the mill-race and has an outcrop of several square 

 yards on the south side of the creek diredlly below the dam. On 

 the opposite side of the stream, however, there is an exposure of 

 hard dark blue to black limestone instead of the shale. The fol- 

 lowing fossils were colle(5led from the Black shale: 



Cardiopsis s^ . , Chonetes lepida (a), Leiorhynchiis limitaris (a), 

 Tcntaculites fissurella (a). 



Station 4.A.~ hXiOvX three and one-half miles west of North 

 Vernon, along the Seymour and North Vernon road, limestone is 

 well exposed along the banks of a small stream. The fos.sils 

 found here are: 



Chonetes yandellanus'f {x), Pleurodictyon problematicnm (a), 

 Spirifer aaiminatiis (c), Spirifer varicosus (r). Streptorhynchjis 

 chenningensis var. arflostriatzis, StrophcodoJita demissa (a), 

 Stropheodonta hemispherica (c), Stropheodonta pcrplana (c), 

 Tcntaculites scalariformis (c). 



About eight miles below the mouth of Sand creek at Rockford 

 the Rockford limestone outcrops in the bed of the river, but no 

 fossils were obtained at the time of my visit owing to the stage 

 of the water. This is the type locality of the Kinderhook fauna 

 and the following is a list of the species which have been de- 

 scribed or reported from it.
