Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. E. Nakkady 1950 | Test almost equally biconvex, wall clearly perforate, periphery broadly rounded, lobulated, umbilical region deeply depressed. All chambers visible from dorsal side, which shows two whorls with six to seven chambers in last whorl. Chambers increase very rapidly in size as added, the last two forming about half the test. Sutures very distinct, depressed. Aperture a large arched opening situated in the median line at base of last formed chamber.
This species is very similar to to A. subbadensis Pijpers, but the chambers are more inflated, the last chamber is invariably large and rounded, and the aperture is characteristically large and arched, whereas it is indistinct in the other species. |
