PLATE VI 
Fig. L Schuchertia magna sp. nov. A poorly preserved specimen, enlarged 
1.7 diameters, photographed under water so as to bring out the individual plates. 
Most of these have been displaced. Near the tip of ray A most of the plates still 
occupy their original relative position; this is true also of some of the plates on 
the distal halves of rays B and E. Those of the central part of the specimen 
evidently have been much displaced. The specimen is valuable chiefly in pre- 
senting the general form and size of the species. About 5^ miles east of West 
Union, miles east of the Stone Church, where the pike crosses a small creek. 
Here the specimen was found in the Brassfield limestone, 30 feet below the base 
of the Dayton limestone, at the top of the limestone exposure immediately 
beneath the bridge. The horizon is regarded as approximately the same as 
that of H emipalaeaster schucherti, although the latter was found over 5 miles 
west of Hillsboro, Ohio. 
Fig. 2. Unknown crinoid. A, base of calyx with traces of the low ridges 
ornamenting the plates; in the figure these traces are emphasized. B, a second 
specimen, preserving better the articulating surface for the attachment of the 
column, C, several additional plates. D, one of the plates, preserving the sur- 
face ornamentation. From the area a mile and a half southeast of Byron, Ohio, 
at the top of the Brassfield formation. Figure 41 on plate 8, vol. 3, Bull. Sci. Lab. 
Denison Univ., appears to represent the same species. The same figure is seen 
on plate 27 of vol. 7 of the Ohio Geological Survey, published in 1895.
