Squares—relict sites, crosses—modern sites. diatomaceous mud belt, this species seems relatively tolerant of oxygen-depleted water, in which ostracod assemblages are generally sparse and of low diversity. In addition, its southward modern limit lies in the vicinity of the maximum southerly intrusion of warm, saline Angola Current water ( Shannon 1985). Palmoconcha? walvisridgensis sp. nov.
