Remarks. Chauliodoniscus armadilloides was found at seven stations. Six of these stations were located near the type locality (63°08’N, 15°40’W, 1301 m, Hansen 1916) in the Iceland basin south of the Iceland-Faeroe Ridge , and the seventh locality is in the southwestern part of the Iceland basin, somewhat deeper (2537 m) than the other stations ( Fig. 12 B). Other records are from the Rockall Trough and the Porcupine Seabight in depth down to 3550 m ( Lincoln 1985b) and from the North Atlantic at 36°to 45°N, at depths between 3663 and 5240 m ( Chardy 1974). Harrison (1989) found this species to be the second most common species at the Permanent station in the southern Rockall Trough .
