Remarks
From Hall (1879, p. 275): “Shell robust, straight, regularly enlarging from the apex. Transverse section, allowing for the degree of compression, sub-circular. Apical angle eight to ten degrees. Air-chambers regular, increasing in depth from the apex, and varying in different individuals from six to ten mm.”
