| Popis: | Eurhamphaea vexilligera Gegenbaur, 1856 (Table 1, Fig. 2) Synonym: Mnemia elegans M. Sars, 1856 Examined material: East coast of Ilh��u da Cal, Porto Santo Island, 33��00���18���N 16��22���13���W and 33��00���19���N 16��22���13.08���W. Several adults were observed during SCUBA diving, and two individuals were collected between 2 and 6 m depth. In Porto Santo harbour (33��3���45���N 16��18���59���W), one specimen was collected at the sea surface (0.5 m depth). Description: Overall, body length of the sampled specimens varied from three to six cm. The biggest specimen, around 10 cm, was observed in situ (West coast of Ilh��u da Cal, 33��00���13���N 16��23���34���W). The body was elongated, narrow with a noticeable compression in the tentacular axis (Fig. 2A). Two horn-shaped processes terminating in the long flexible filament are drawn out at the aboral apex (Fig. 2B). Subtentacular ctene rows extend onto these processes. Reddish-brown ink vesicles with bioluminescent properties follow the path of the substomodeal meridional canals (Fig. 2C).
