Erroneous— Henricia sanguinolenta (Müller, 1776)

Reports for the Azores:

Henricia sanguinolenta (M̹ller, 1776)— Koehler 1921b: 31, fig. 23; Mortensen 1927a: 118–121; Nobre 1938: 39–40, fig. 14.

Type locality: south coast of Norway .

See: Madsen (1987: 209–218, figs. 1, 2a–b, 4–9); A.M. Clark & Downey (1992: 396–397, figs. 60o–p, pl. 93, fig. F, pl. 95, figs. H, I).

Occurrence: Northeast Atlantic, from north boreal and arctic waters south to Northumberland (c. 55°N) and Kattegat in the east and to Cape Cod in the west ( Madsen 1987); reported elsewhere from the Canaries ( Hernández et al. 2013); possibly extending the North Pacific waters ( Madsen 1987).

Depth: 0–200 m, though rarely below 50 m (A.M. Clark & Downey 1992).

Habitat: mainly on hard substrata (A.M. Clark & Downey 1992).

Larval stage: lecithotrophic (brooder; A.M. Clark & Downey 1992).

Remarks: in the historical literature, the inclusion of Henricia sanguinolenta in the Azorean marina fauna was based on the assumption that H. oculata was a junior synonymous of the former species (see remarks under Henricia oculata ).
