In some places,—as, for example, at Station 54, between Scotland and Fieroe, and Station 15, between the west coast of Ireland and the Porcupine Bank,—there seem to be regular banks of it, the dredge coming up loaded with fragments, living and dead. Five allied species of the genus Amphihelia oc- curred more Fig. G8.— Flabelhtmdistinctum Twice the natural size. (No. 2S, 1870.) Allopora oculina, Ehrenberg, a very beautiful form, of which a few specimens were procured in the ' cold area,' at depths a little over 300 fathoms. Thccopsammia socialis, Pourtales (Fig. 09), a form closely allied to Balanophyllia, and resembling some crag species. It had been previously dredged by Count Pourtales in the Gulf of Florida. Thcco- psammia is tolerably common in deep water in the ' cold area,' growing in patches, five or six examples sometimes coming' up on one 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 Thomson, C.
