May, 190'9.] The Bedford Fauna at Indian Fields, Ky. 5 1 9 



stratigraphy of the Lower Waverly of Kentucky was unravelled. 

 Schuchertella niorsei is closely related to Orihothetes niinutus, 

 Clarke, from the lower limestone in the Marcellus shales of New 

 York, and may be a diminutive descendant of Streptorkynchiis 

 flabellum, Whitfield, from the Columbus limestone of Ohio. Its 

 relations to Orthothetes minuUts, Cummings, from the Salem 

 lioestone of Indiana, are less evident. Septa and dental plates 

 are absent in the pedicel valve, the hinge area is rather high, but 

 the beak is not distorted and there is no evidence of attachment 

 of the shell by cementation. 



Schuchertella herricki, sp. nov. (Fig. 16). 



Shell usually transversely elongate, but sometimes attaining a length 

 which is almost as great as the width. The valves were thin and are 

 preserved as strongly flattened specimens which suggest that originally 

 the brachial valve was gently convex and the pedicel valve either flat or 

 slightly concave. In one pedicel valve the arching deltidium and the 

 moderately elevated cardinal area are preserved. The casts of the 

 brachial valve show the impressions made by the crural plates, the pos- 

 terior border of the flattened cardinal process, and a trace of a inedian 

 ridge traversing the space occupied by the muscular impressions. Radiat- 

 ing striae narrow and numerous, varying between 5 and 7 in a width of 

 2 mm., counting both the more prominent striae and those which evi- 

 dently have been intercalated later. While the difference in size of the 

 radiating striae is readily perceptible under a lens, they appear subequal 

 to the unaided eye. Concentric striae very fine and visible only under 

 a lens. Width of an average specimen, 22 mm.; length, 16 mm.; height 

 of cardinal area, a little over 1 mm. 



Abundant in the thin representative of the Bedford-Berea 

 about a mile northeast of Indian Fields, Kentucky, along the 

 road running from the Brownlow Bruner farm on Lulbegrud 

 Creek northwestward toward Kiddville. Named in honor of 

 Prof. C. L. Herrick, whose investigations, on the Paleontology of 

 the Waverly of Ohio contributed materially to our knowledge. 



Chonetes sp. (Fig. 10). 



A small species, 6.2 mm. in width and 4.5 mm. in length, with 5 to 6 

 radiating striations in a width of 1 mm. In one specimen, a narrow 

 median striation extends along the base of a narrow median groove from 

 near the beak to within a short distance of the anterior margin of the 

 shell, somewhat resembling a figure of Chonetes coronaia, published by 

 Hall and Clarke (Volume VIII, Paleontology of New York). Traces of 

 the brachial ridges may be seen, but not enough is known for identification. 



In the thin representative of the Bedford-Berea at Indian 

 Fields, Kentucky. Apparently the same species is found in the 

 corresponding la^^er at Irvine, Kentucky. 



Productella sp. Very much flattened impressions of the 

 interiors of the brachial valves of a small species of Productella, 

 usually not over 8 mm. in length are not uncommon in the thin 

 representative of the Bedford-Berea at Indian Fields, Kentucky. 

 Much smaller specimens, not exceeding 2.5 mm. in length, found 

 at the same horizon at Irvine, Kentucky, may belong to the 

 genus Strophalosia.
