To prove the morphological resemblance of Kerunia andBelosepia I have thought it best to figure two cross-sectionsrepresenting both organisms together (text-figs. 1 & 2).These exhibit the turned-back ventral lip, separated from thefirst spine by a deep transverse cleft, and beyond this firstspine in Belosepia rugosities are visible, Avhile in Kerunia Ann. i& May.
