Recorded in nine AFEN samples from the Ymir Ridge, Hebrides Slope, Barra Fan, and North Rockall Trough, at depths 1312–2046 m; five samples from the BIOFAR survey, from the Lousy Bank, Iceland-Faroe Rise [South], and Iceland Basin, at depths 597–1157 m; 53 BIOICE samples, from the Denmark Strait, Iceland Basin, Iceland-Faroe Rise [South], Irminger Basin, and Reykjanes Ridge, at depths 497–2177 m. The highest abundance (sample count) was 677 specimens in BIOICE sample 2337 from the Iceland Basin, at 1099 m. Distribution elsewhere. From North Feni Ridge to the South Biscay Slope, 1160–2890 m (Bird & Holdich 1988). Also recorded from the Georges Bank (North-West Atlantic) at 2257–3236 m (Larsen 1999 a); Denmark and Davis Straits at 1441–2193 m (Hansen 1913), and the North Sea off Northumberland (NE England) at <200 m (Bamber 1986). Remarks. As with the previous study (Bird & Holdich 1988), in some samples this agathotanaid has proved to be one of the most abundant tanaidaceans, particularly those from the Iceland Basin. The new records also confirm that A. ingolfi is excluded from the ‘cold-water’ zone North of Iceland, the Faroes and the Wyville-Thomson Ridge (Fig. 1), and it is found where benthic temperatures average between 2 o to 6.5 o C (mode 4 o C).
