In 1858, Fritz Müller published an account of a number of annelids collected by him on Santa Catarina Island, off the southern coast of Brasil (Müller, 1858). Among others, Müller presented the description of a new genus, Magelona. The observations reported by Müller were of a quite general nature and were confined to comments on the prostomium and the palps, the number of segments and the presence of simple setae in the anterior region, the presence of hooks and lamelliform structures on posterior segments, and the presence of a pair of anal cirri and an eversible proboscis. The latter half of the original description dealt with the blood, its circulation, and the structure of curious segmental vascular loops provided with pulsatile ampullae, since considered elsewhere (McIntosh, 1878b, pp . 447-448, Pl. 36, Figs. 3 and 4; 1879, pp. 341-342; 1915, pp. 221-222. Jones, 1968, pp. 285-287, Figs . 23, 25). Müller's accompanying illustrations are of a vascular loop, along with the lateral lamellae of that segment (Müller, 1858, Fig. 10) and of a single hooded hook which shows no details of its dentition (Müller, 1858, Fig . 11) . While the description is adequate to define the genus, it offers little which might be used to diagnose Müller's species, M. papillicornis. Further, no specific type locality is given, merely "Insel Santa Catharina."
