Remarks

Maynard (1920d:116) reported this taxon to be abund­ant, but mostly dead.  Out of 1500 specimens collected only 70 were living.  Maynard (1924a:167) contradicted this number, stating that of 953 collected, 70 were living, and provided more detailed descriptions of the shell, ecology and anatomy of this taxon.  Clench & Aguayo (1951) considered Cerion asperum to be a valid species and the senior synonym of Strophiops scalariformis.
