Busk says that the shallower-water species ai)pear to have the widest geographical distribution. That is apparently not the case with the species collected by the " ; According to Professor Smitt's Reports we may mention among the " Blake " Bryozoa the cosmopolitan Crisia eburnea, the form known as C. denticulata (Figs. 323, 323 a), and, from 306 fathoms, the Scandinavian Diastopora repens (Figs. 324, 324 a), a well-known ramified form creeping on Terehratula cii- bensis. This species is also characteristic of the crag, and per- haps identical with a cretaceous form. It seems as if the species of this group assumed a somewhat more elongate and simpler form in proportion to their bathymetrical range. Busk, from an examination of the extensive collection of the " Challene'er," considers the species of Farciminaria (Figs. 325, 325 a) as the most characteristic of the abyssal bryozoans, the preeminent forms of the delicate and flexible types inhabiting the tranquil depths of the ocean.
