Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. R. Loeblich and H. Tappan 1984 | Test a low conical spire, proloculus immediately followed by rounded chambers, two to three or four in the first whorl, and lacking a tubular nonseptate second chamber, later whorls may be reduced to fewer chambers per whorl; chambers with secondary partitions as in Patellina.
M. Jurassic to L. Cretaceous, Holocene. Type genus: Ashbrookia McCulloch, 1977. Remarks: Differs from the Placentulininae in having secondary partitions, and from the Patellininae in lacking an undivided tubular second chamber. |
