Original Description
Test almost equally biconvex, wall clearly perforate, periphery broadly rounded, lobulated, umbilical region deeply depressed. All chambers visible from the dorsal side, wich shows two whorls with six to seven chambers in the 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 opening situated in the median line at base of last formed chamber.

Size: Length of holotype, 0.25 mm; thickness, 0.15 mm.; breadth, 0.20 mm.

Extra details from original publication
This species is very similar 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.

This species has been found in four sections. It is best represented and flooding in the top shale sample at Abu Durba. Elsewhere it is rare to frequent. It has not been found at Wadi Danili.

You are certainly right but we do not refer to the same publication?

Thanks, but actually it looks like I was completely wrong and the 1951 was a typo, corrected now.
