Fig. XLIV. The distribution of Cladocarpus integer in the northern Atlantic. In the hatched regions the literature denotes a scattered occurrence. The species is a typical warm atlantic form, which appears to have its chief occurrence in the western Atlantic, in the lower part of the littoral region and the upper part of the abyssal. In northern waters, it has long been known from the west coast of Norway, and is also found to be a not alto- gether infrequent visitor to Greenland, both in Davis Strait and up towards Daumark Strait (fig. XLIV). On one occasion, it was met with off the east coast of Iceland, at the boundary of the arctic deep region. That it has not yet been located with certainty between the British Isles and Iceland must be due to accident. Ritchie (1912 p. 228) had before him a specimen brought home by Hull trawlers, and we may doubtless presume that it would then have originated from the northern slope of the North vSea plateau or from the Faroe Islands Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Danish Ingolf-Expedition, 1895-1896; Wandel, C
