ECTENOGLOSSA ? SCULPTA Cooper, new species 
Plate 4, C, figures 9-13 
Shell fairly large, light bluish gray in color on the outer surface but with inner 
layers grayish brown; outline longitudinally and narrowly elliptical; sides sub- 
parallel, gently convex ; widest at about the middle; anterior narrowly rounded ; 
posterior bluntly pointed but apical angle unknown; surface marked by closely 
crowded, elevated concentric lines and ridges, most prominent on the lateral 
slopes; concentric ornamentation crossed by fine radial striae which are most 
prominent in the median region. 
Pedicle valve slightly deeper than the brachial one; greatest depth at about 
the middle with long, gentle anterior and posterior slopes; anterior profile fairly 
strongly convex with moderately steep lateral slopes. Brachial valve with nar- 
rowly rounded posterior margin; lateral profile flattened in the median half and 
with the anterior and posterior quarters sloping to the extremities. Anterior pro- 
file slightly less convex than that of the pedicle valve. 
Measurements in mm.—Holotype, length 25.7, width 14.9, thickness 7.7. 
Types.—Holotype: 109302b; figured paratype: 109302a; unfigured paratype: 
109302c. 
Horizon and locality—Bromide formation (Pooleville member-O xoplecia 
gouldi zone) in Carter County, Okla.: Rock Crossing of Hickory Creek, about 
center sec. 35, T. 5 S., R. 1 E., Criner Hills; on a branch of Hickory Creek in 
NW43 sec. 26, T. 5 S., R. 1 E., Crier Hills. 
Discussion.—This species is doubtfully referred to the genus Ectenoglossa 
because of its long and slender form, but the “teeth” referred to by Sinclair, 
author of the genus, were not seen. The species is further distinguished by the 
radial elements on an otherwise Lingula-like ornament. It differs from E. nym- 
phoidea by its more slender dimensions and details of the ornamentation. 
ECTENOGLOSSA sp. 1 
Plate 8, B, figures 4, 5 
Shell thin, large for the genus, oval in outline, width about two-thirds the 
length; posterior margin somewhat narrowly rounded; sides gently curved; an- 
terior margin slightly more broadly rounded than the posterior margin. Great- 
est width at the middle. Surface marked by fine concentric lines and broad con- 
centric undulations.
