Description. Among the collection of Lower Mercer fossils at 

 hand are several fragments of a large species of Conularia. The re- 

 semblance to C. newberryi of the Waverly formation of Ohio is so close 

 that identification with that species might be made with considerable 

 confidence were it not for the different stratigraphic position of the 

 forms and the fragmentary condition of the material at hand. The 

 size is approximately the same as that of C. newberryi and the surface 

 is marked by sharply elevated, finely crenulated, transverse costae 

 separated by wide furrows. The costae are arched forward and are 

 either continuous across the median line or terminate abruptly so 

 that the ends alternate in position; about ten to twelve costae occupy a 

 space of 10 mm. A similar form was figured by Herrick from the 

 Lower Mercer limestone at Flint Ridge. Our forms do not show the 

 thickening at the inner ends or in the middle of the costae which char- 

 acterizes the form from the Kanawha Black Flint of West Virginia 

 referred to by Price as C. crustula ?. x

Meek s description. "The only specimens of this shell that I have 

 seen are flattened by accidental pressure. The most nearly perfect 

 specimen in the collection is 2.80 inches in length, with a breadth (as 

 seen flattened in the matrix), at the larger broken end, of about 0.95 

 inch, and with sides diverging from the smaller, rather bluntly pointed 

 extremity, at an angle of about 18 degrees. At and near the smaller end 

 the surface is marked by very minute, crowded, transverse, or annular 

 striae. About three-fourths of an inch farther up, these striae gradually
