DESCRIPTIONS OF FOSSILS FROM THE CINCINNATI 
GROUP. 
By U. P. James. 
Genus Lineuta, Bruguire. 
LINGULA NoRWooDI, James (Pl. X., fig. 1). 
Lingula norwoodi, James. Cin. Quar. Jour. of Science, vol. ii., p. 
10, Jan. 1879. 
Shell long, suboval in outline ; beak obtusely pointed ; outward 
rounding slopes, rather sudden at first from the beak, then more gentle 
at the sides, to about #ths of the entire length, where the curve is more 
abrupt but even around the front margin. Regularly and evenly con- 
vex transversely; surface marked by distinct but delicate concentric 
lines of growth. Length of the specimen used for this description a 
little over two lines, breadth about one line. 
Found by the writer embedded in subcrystalline limestene on the 
left bank of the Ohio river, opposite the lower part of Cincinnati, about 
30 feet abovelow water mark. Other specimens have been found simi- 
larly embedded, about the same average size, none larger. 
Named in honor of Prof. J. G. Norwood, of Columbia College, Mo. 
The object in republishing this species is to give a fuller description 
and better figure than the originals. 
Genus Monticuripora, D’Orbigny.

The corallum of the type specimen of this species is subfusiform in 
general outline, with rough, nodular swellings, and low compressed 
ridges, and annular constrictions: parasitic, acrinoid stem the central, 
or subcentral object, upon and around which it is grown: tapering at 
each end to a little more than the size of the stem—about three eighths 
of an inch at one end, and one fourth of an inch at the other. When 
found, the spevimen was broken into five pieces, exhibiting clearly the 
parasitic habit, the stem seen as passing entirely through, from end to 
end. The corallites radiate from the central object, and have a slight 
upward inclination at first, then curve directly in a slightly wavy 
course to the outer surface. Slightly raised, rounded monticules,
