Compared with Lingula melie, this species is distinctly 
broader and more oval in form; moreover, all specimens found 
so far are considerably smaller. Compared with Lingula nieeki 
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 Orbiculoidea 
newberryi the apex of the brachial valve appears to be nearer the 
center; and the pedicel afea, 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 
AH 11 of the Paleontology of New York) in a typical specimen of 
Orbiculoidea newberryi obtained from the type locality, at 
Cuyahoga Falls, Ohio. Our shell appears to be related more 
closely to Orbiculoidea lierzeri , 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 morsei, sp. nov. (Fig. 1). 
Species of persistently small size. Valves transversely elongate, 
with the greatest width at the hinge-line. Pedicel valve with a high 
cardinal area and a prominent deltidium; 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 liner 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-Berea in 
the northeastern part of Irvine, Kentucky; rare at the same 
horizon northeast of Indian Fields, Kentucky. Named in honor 
of Mr. AAA C. Morse, in whose delightful companionship the
