Compared with Li)igiila iiielie, this species is distinctly 

 broader and more oval in form; moreover, all specimens found 

 so far are considerably smaller. Compared with Lingtila meeki 

 Herrick, the shell is distinctly smaller, the beak is less prominent, 

 appears less attenuated, and the horizon is considerably lower. 

 Rare in the thin representative of the Bedford-Berea at Irvine, 

 Kentucky. 



Orbiculoidea sp. (Fig. 12). Compared with Orhiculoidea 

 newherryi the apex of the brachial valve appears to be nearer the 

 center; and the pedicel area, though supplied with a strongly 

 elevated, sharp, median ridge, is not supported on a distinctly 

 elevated oval platform, as figured by Hall and Clarke (Volume 

 VIII of the Paleontology of New York) in a typical specimen of 

 Orbiculoidea neivberryi obtained from the type locality, at 

 Cuyahoga Falls, Ohio. Our shell appears to be related more 

 closely to Orbiculoidea herzeri, but the apex of the brachial valve 

 is too central. A small median striation or septum extends for- 

 ward a short distance from the apex of the pedicel valve along its 

 interior. This is probably a new species, but too imperfectly 

 characterized as yet to receive a name. Concentric striae fine 

 and numerous; some of them, at various intervals, more strongly 

 elevated than others. Outline nearly circular. Lateral diameter 

 about 8 mm. Height of the brachial valve, a little less than 3 mm. 

 In the thin representative of the Bedford-Berea at Indian Fields, 

 Kentucky; not rare. 



Orbiculoidea sp. (Fig. 13). The apex of the brachial valve of 

 this species is too far from the center to make it at all likely that 

 this species is identical with the one found at Indian Fields, 

 mentioned above. It is a smaller species apparently, and the 

 concentric striae are less distinct. The largest specimen found 

 has a length of 5 mm. In the thin representative of the Bedford- 

 Berea at Irvine, Kentucky. 



Schuchertella inorsei, sp. nov. (Fig. 1). 



Species of pensistently small size. Valves lransver.sely elongate, 

 with the greatest width at the hinge-line. Pedicel valve with a high 

 cardinal area and a prominent deltiditim; surface sloping rather evenly 

 from the beak to the margins of the .shell, but appearing convex owing to 

 the elevation of the beak. Brachial valve either flat or slightly concave, 

 usually elevated at the beak into a tiny knob. Radiating striae 25 to 30, 

 of which only the alternate striae may be considered as primary, although 

 some of the secondary striae originate near the beak; radiating striae 

 narrow, with wide interspaces, crossed by finer concentric lines, visible 

 only under a lens. Length, 2.6 mm. ; width 4.5 mm. ; elevation of cardinal 

 area 1 mm. 



Abundant in the thin representative of the Bedford-Bcrca in 

 the northeastern part of Irvine, Kentucky; rare at the same 

 horizon northeast of Indian Fields, Kentucky. Named in honor 

 of Mr. W. C. Morse, in whose delightful companionship the
