1927 Haplophragmoides excavatus ; Cushman and Waters, p. 82, pl. 10, fig. 3a-b.

2005 Haplophragmoides excavatus Cushman and Waters ; Kaminski and Gradstein, p. 360, pl. 82, figs. 1-7.

Material. Four specimens from three samples.

Description. Test free, subcircular in outline, planispirally involute coiled with depressed umbilicus, lobate and carinate periphery. Chambers (12–13 in the last whorl) increase very slowly in size. Sutures few incise. Wall finely agglutinated, surface smooth.

Distribution. Late Cretaceous–Oligocene ( Kaminski and Gradstein, 2005).

Remarks. Haplophragmoides excavatus differs from H. carinatus and H. walteri in having a more circular periphery, and a greater number of chambers in the last whorl.
