Origin, developmental changes and homologies of the stage morphostructures were considered according to their location in three morphogenetic fields. The first, or central, field forms at the prodissoconch I stage. It can be inherited by prodissoconch II and nepioconch stages in one taxa, or PD-II, N and dissoconch stages in others. The second, or postero-dorsal, field appears at the N stage, and the third field, or antero-dorsal, at the D stage.

主要对3个形态发生区域的阶段形态结构的起源、发育变化和同源性做了研究，其一，即中央区域，开始形成于前双壳I期，在某个分类单元它可以在前双壳II期和幼贝期形成，而在其它分类单元则在前双壳II期、幼贝期和双壳期形成；第二区域，即背部后区，在幼贝期出现；第三区域，即背部前区，出现于双壳期。
