The fact that even in the Persian material these processes are sporadic (even on the same specimen) suggests that this is a variable character within this species. The degree of protrusion of these processes, and hence their conspicuousness may depend on the degree of contraction of the specimen. It is possible that these processes move in and out under coelomic pressure. We believe this to be the same species as those specimens observed from
