Cistenides granulata (Linnaeus, 1767) Figs 1C, 2C, 3C, 4 C–D, 8 – 9 Sabella granulata Linnaeus, 1767: 1268. Pectinaria granulata – Hessle 1917: 77. Pectinaria (Cistenides) granulata – Nilsson 1928: 28. — Pettibone 1954: 312, fig. 35i–k. — Holthe 1986: 24. — Hartmann-Schröder 1996: 482. Material examined (23 specimens, 2.2% of total specimens identified, in three samples) ICELAND – North and North East coast • 7 specs; BIOICE station 30, sample 2042; 65º49′56″ N, 14º32′94″ W; 24 Jul. 1991; 3.1ºC; salinity unknown; 105 m depth; sediment unknown; MNCN 16.01/17988 • 9 specs; BIOICE station 27, sample 2126; 66º59′51″ N, 18º49′82″ W; 8 Jul. 1992; 2.7ºC; 34.86 ppm; 208 m depth; sandy gravel and stones; IINH-40466 • 7 specs; BIOICE station 23, sample 3249; 65º50′34″ N, 12º01′27″ W; 14 Jul. 2001; 1.92ºC; 34.87 ppm; 192 m depth; sediment unknown; IINH-40467. Occurrence From off northern and north-eastern coast of Iceland. Depth range: 105 to 208 m (Fig. 1C); bottom temperature range: 1.92 to 3.10°C (Fig. 2C). Water mass/es: MEIW. Remarks All diagnostic characters for this species – type locality: Northern Europe (Holthe 1986) – as stated by Holthe (1986) are present in BIOICE material: shape and number of paleae and cephalic veil (Figs 4C, 8A, 9A), scaphal shape, anal lobe and anal papilla (Fig. 8F). Ventral uncini agree well with those present in the genus, not showing variations within uncinigers nor along the body both in large (Fig. 8 B–E) and small (Fig. 9 B–F) specimens; there is only one row of teeth becoming progressively smaller in size from the uncinus base (at the level of the subrostral process) towards the distal end. This lack of variation, which has been considered the typical pattern in the family, was only found in C. granulata among the four pectinariid species in BIOICE samples.
