FIGURE 6. Eucidaris metularia (SAMC-A28226): A . Map showing distribution. B . Side view of preserved specimen. C . Apical system of preserved specimen. Identification. Test with well-defined plate outline, conspicuous apical disc, flat or evenly sunken, naked ocular usually exsert, but in some cases ocular I, IV and V may be insert; apical disc smaller than protruding peristome. Interporiferous zone of ambulacra somewhat naked. Spines short, stout, distally crown-shaped and sometimes tapered, distinctively banded, with longitudinal ridges distally. Global maximum size. Maximum test diameter 30 mm . Global distribution. Mozambique, East coast region of South Africa ( Filander & Griffiths 2014 ), and Red Sea to Fiji, Gilbert and Hawaiian Islands, and from South Japan to north coast of Australia, at 5 – 570 m depth ( Mortensen 1928a ; Schultz 2010 ). Remarks. Marshall & Hodgons (1991) reported on a specimen collected in Presley Bay housed in the East London Museum, but gives no accession number for it. Seven records have been logged in the Royal Museum of Central Africa database and these form part of the samples collected by Samyn & Thandar (2003) . Mortensen (1928a) highlights variations within the species, which include spines of some specimens being stout and blunt, whereas in other cases spines are fusiform, latter usually a feature of deep-water specimens. Moreover, color variation amongst adults and juveniles may also exist; young specimens being more vividly colored than adults. The number of longitudinal ridges may also vary with age, being greater in adults than in juveniles. However, none of the above variations where observed in specimens analysed by the authors.
