REMARKS

The investigated specimen collected off southern Madagascar corresponds well with the species Crania roseoradiata described by Jackson (1952) from South Africa. The shell is small, circular, with a low, subcentral apex. The muscle scars are well marked ( Fig. 2C View FIG ). The posterior adductor muscle scars are large, rounded, and widely separated, while the anterior muscle scars are elevated and kidney-shaped. In the anterior half of the shell impressions of branching mantle canals are observed.

In the character of the muscle scars this species shows similarity with Novocrania anomala (Müller, 1776) from the Mediterranean and northern Atlantic ( Logan & Long 2001). Emig (2014) regards N. anomala and N. turbinata (Poli, 1796) as synonyms, based mainly on molecular analyses (see Cohen et al. 2014). Jackson (1952: 9) advocated a revision of the two forms, which Emig (2014) has now done.
