This remarkable foraminifer, 'bristling with borrowed spicules', as Brady remarked, was originally regarded as a sponge before its true affinities were recognized by Carter. Carter's description includes these interesting details about the soft parts, 'Animal occupying the cavity of the test, consisting of semitransparent yellowish sarcode charged with granules and oil globules, frustules of Diatomaceae, especially Melosira, dark brown bits of Fucus, and reproductive cells'.

This remarkable foraminifer, 'bristling with borrowed spicules', as Brady remarked, was originally regarded as a sponge before its true affinities were recognized by Carter. Carter's description includes these interesting details about the soft parts, 'Animal occupying the cavity of the test, consisting of semitransparent yellowish sarcode charged with granules and oil globules, frustules of Diatomaceae, especially Melosira, dark brown bits of Fucus, and reproductive cells'. Details of the wall are shown in PI. 1, fig. 6. It will be noted that in some cases it is the pointed tip in other cases the rounded base of the sponge spicule that sticks out. Hedley & Wakefield (1967) have shown that the inner lining of the test is of fibrous protein, possibly collagen, imparting a flexibility that may be of adaptive value in the turbulent zone. Distribution. This species occurs as a fixed form among weeds in the Laminarian zone. It is possibly widespread around Great Britain and it appeared as a juvenile form on weed covered cobbles gathered from Sarn Cynfelyn and kept in a tank for some months. The original specimens were from Hastings (Sussex) and Carter's specimens came from Budleigh Salterton, Devon, found on Laminarian holdfasts and the fronds of Phyllophora. Other British records are Wembury, Devon (Hedley & Wakefield, 1967); Torbay, Devon (Parfitt, 1878); Jersey (Kent, 1878); Dublin Bay (Haddon, 1886); Colwyn Bay and Dee (Siddall, 1878, 1886); Clare Island (Heron-Allen & Earland, 1913b). Diagnosis. A species of Hippocrepina with subovate to elongate ovate test, slightly irregular but tending to be widest at the apertural end which is slightly produced and truncate with the aperture within a depression. Genus HIPPOCREPINA Parker, 1870 Hippocrepina species A (PL 2, fig. 4; Text-fig. 2, nos 1-4). 00 Fig. 2, 1-4. Hippocrepina species A.
