Remarks. This is one of the commoner bathyal species in the waters around Japan. The protruding neck of A. separans is annulated, whereas that of A. scalaris is smooth and elongate; for this reason, previous records of A. scalaris from Japan are in fact A. separans as listed, in part, in the synonymy by Loeblich and Tappan (1994). Separation of chambers is not a prime feature in the identification of this species, irrespective of the specific name. In addition, we here show a broken and separated unilocular specimen to illustrate that such specimens may induce erroneous identification as a unilocular species.
Occurrence. Common in all the formations of the present study.
