Uncinulus schucherti. 
(Plate If Fig. ig.) 
Shell resembles Wtlsonia saffordi, but that part of the ventral 
valve occupying the fold projects far less beyond the lateral mar- 
gins of the shell. The dorsal valve is more evenly convex. The 
anterior face of the shell is not flattened, so that a profile view is 
less angular. Plications on the mesial fold vary from 4 to 5; of the 
lateral plications 7 to 10 are distinct, and 2 to 4 indistinct. Larg- 
est specimen, 15 mm. long. Globular or moderately elongated. 
Named in honor of Mr. Charles Schuchert. 
Linden bed; above the quarry north of Perryville, Tennessee. 
Stephanocrinus tennesseensis. 
(Plate I, Figs. 4 A, B.) 
Closely related to Stephanocrinus osgoodensts. Body approxi- 
mately inversely conical, the sides diverging at angles varying from 
50° to 60°; constriction at base usually slight; base usually sharply 
pointed and triangular in cross-section; some specimens less acute 
at the base; cavity for reception of stem either very minute or 
obsolete. Length to base of ambulacral grooves 6.5 to 7.5 mm.; 
length of interambulacral projections of the body, 2 mm. Surface 
granulose; the granules are arranged more or less serially in direc- 
tions corresponding to that of the striae of the distinctly striated 
species, and in these directions the granules are usually more or 
less elongated, but at first sight the granulation is more obvious 
than is the arrangement of the granules according to some design. 
In Stephanocrinus osgoodensis the surface is traversed by fine 
closely arranged striae, the base is less acute, more triangular below, 
and the cavity for the insertion of the stem is more distinct. 
Waldron bed: Iron City, at station; Clifton, three-quarters of a 
mile above landing, along the river; Swallow Bluff, along upper 
part of bluff south of landing; along road leading east from New 
Era, following the Waldron bed outcrop for a considerable dis- 
tance; all in Tennessee. 
Eucalyptocrinus springeri,. sp. nov. 
(Plate IV f Fig. 73.) > 
This species is closely related to Eucalyptocrinus elrodi, from 
the Waldron bed, at Waldron, Indiana, but differs in the charac-
