Anoplotheca saffordi. 
{Plate /, Fig. 6) 
Length, 5 mm.; convexity, 2.8 mm. Pedicel valve strongly con- 
vex, v^ith the 3 median radiating plications (the middle one nar- 
rower) forming an indistinct elevation, with 4 distinct and one 
indistinct plication on each side; the beak projecting but slightly 
beyond that of the brachial valve. Brachial valve concave, espe- 
cially anteriorly along the shallow median depression; depression 
occupied by 2 radiating plications placed close together and sepa- 
rated by a short space from the lateral plications of which 4 are 
distinct and one indistinct. 
Brownsport bed; in the massive limestone near the top of the 
Brownsport exposure, northeast of the stables on the Gant place, 
northeast of Martins Mills; Bath Springs; east of George Wilson, 
seven and one-half miles east of Savannah; all in Tennessee. The 
same species, described as Anoplotheca congregata^ by E. M. Kin- 
dle, occurs in the Kokomo limestone at Logansport, Indiana. 
Homoeospira schucherti. 
{Plate I, Figs. 10 A, B.) 
Shell broadly ovate; length of one of the type specimens, 1 1 mm. ; 
width, 10.3 mm.; thickness, 6.8 mm. Both valves with a shallow 
median groove or depression most distinct anteriorly, usuallv occu- 
pied by one or two plications originating in the groove a short 
distance anterior to the beak, less distinct than the remainder; 
about 7 distinct and i indistinct radiating plications on each side 
of the median groove. Length of largest specimen seen, 13 mm.; 
named in honor of Mr. Charles Schuchert. 
Brownsport bed: Brownsport Furnace, Tennessee. 
Homoeospira schucherti-elongata, var. nov. 
{Plate I, Figs, g A, B.) 
Shell smaller, narrower, median groove more distinct, radiating 
plications usually narrower and closer together', as in fig. 9 B; 
about 8 distinct plications on each side of the median groove, with 
one or two less distinct plications within or along the walls of the 
groove. Shell narrower and more convex from side to side, the 
beak of the pedicel valve more incurved over that of the brachial
