R. cuboides type identical with R. intermedia Barris, and a 

 large Choneies which I propose to call C. cancellata. . 



I have said that Spirifera -pennata does not range through 

 the entire series of beds to which its name is here attached. It 

 is in reality confined chiefly to the upper portion of the beds. 

 In the quarry at the west end of the bluffs described above, 

 the uppermost layers exposed are lower than the horizon of 

 this large spirifer. A quarrj' recently opened near tlie eastern 

 end of the bluff includes spirifer-bsaring layers that are geo- 

 loofically higher than an}^ layers in the west quarry. 



The pennata beds are well developed in quarries within the 

 city limits of Independence, about a quarter of a mile east of 

 the court house. The same beds are exposed in a number of 

 quarries from a mile to a mile and a half farther east. It 

 was in one of these quarries about a mile east of the city that 

 the Independence shales were penetrated in an unintelligent 

 search for coal. The first shaft that reached the shales was 

 made by Mr. Kilduff, m the bottom of a quarry that had 

 previously been worked well down into the Barren beds. The 

 shaft before it reached the shales passed through the Gyro- 

 ceras beds, but at the point where the excavation w^as made 

 these beds appear not to have been brecciated. 



In all the quarries about Independence the S. pennata beds 

 pass up into harder layers containing few brachiopods, but 

 holding numberless specimens, unsatisfactory for cabinet pur- 

 poses, of CystiphyUuni americamun Ed. and H. A few other 

 corals, as for example Favosiies dwnostis Winchell, Favosites 

 plaeenta Rominger, Alveolites minima Davis, and very ^^^x- 

 mg\y Ileliopliylliini kaUi Ed. and H., are associated wath Cysti- 

 phyllum. In some of the quarries east of Independence, beds 

 containing Acervularia profunda Hall, are found to occupy a 

 position immediately over the horizon of CystiphyUiim\ and 

 the whole assemblage of coral- bearing layers, from the 

 horizon at which the Cystiphyllums begin to the summit of 

 the layers containing Acervularia profunda, has been called 

 Acervularia profunda beds. That magnificent coral, Phillip-
