Spring Creek, N} sec. 17, T. 2 S., R. 1 W., Murray County. 
Discussion.—This species is represented by four specimens. Two of the speci- 
mens are apparently young. The species is characterized by its nearly smooth 
umbo, the densely granulated median region and the more distant well-aligned 
pustules on the flanks and anterior. It differs from G. papillosa from the Pratt 
Ferry Formation in its much larger size, less tapering sides and proportions. 
GLOSSELLA PAPILLOSA Cooper, new species 
Plate 5, G, figure 19; plate 9, J, figures 26, 27; plate 11, G, figures 12-14 
Shell of about medium size for the genus, wider than long, the length about 
twice the width; beak pointed, forming an angle of about 70°. Anterior margin 
narrowly rounded; sides subparallel ; surface marked by extremely fine pustules 
densely matted in the median region but forming closely spaced rows on the 
flanks and anterior region. Umbonal region marked by concentric undulations 
and growth lines only. 
Pedicle valve gently convex in lateral profile and broadly convex in anterior 
profile. Brachial valve considerably deeper than the pedicle one; lateral profile 
gently convex but most convex in the umbonal region; anterior profile moder- 
ately convex with a well-rounded median region and moderately long, steep 
lateral slopes. 
Measurements in mm.—Holotype, length 11.3, width 7.0. 
Types—Holotype: 116787b; figured paratypes: 116787d,e, 123305; unfigured 
paratypes : 116787a,c. 
Horizon and locality.—Pratt Ferry formation in Alabama: 0.2 mile southeast 
of Pratt Ferry, Blocton (15’) Quadrangle. 
Discussion—This is a much smaller species than G. liumbona from the Poole- 
ville member of the Bromide formation and is much more oval in outline. 
GLOSSELLA sp. 1 
Plate 3, A, figure 1 
This is the impression of about the posterior half of a linguloid having a prob- 
able length of about 12 mm. and a width of 5 mm. The specimen is an impres- 
sion of the exterior showing numerous wavy lines and a mat of fine pustules. 
Figured specimen.—109319. 
Horizon and locality—Botetourt formation in Virginia: Junction Virginia 
Highways 114 and 311, 4 mile southwest of Catawba, Salem (15’) Quadrangle. 
Superfamily TRIMERELLACEA Schuchert, 1929 
Family TRIMERELLIDAE Davidson and King, 1874 
Large, thick calcareous brachiopods usually subcircular to broadly oval in 
outline and lenticular in profile; pedicle attachment area large, triangular and 
transversely striated. Muscle scars of both valves large, and often elevated on 
thickened or hollow platforms.
