“The extreme depth from which any Polyzoa were procured was 3125 fathoms, at 
Station 253 in the North Pacific. In this haul there were four species attached to a 
manganese nodule, from a bottom of red clay, and associated with them were two or three 
minute specimens of a species of Stephanoscyphus. Of the four species thus living at a 
depth of about 3^ miles, only one perhaps can be regarded as belonging to a decidedly or 
almost exclusively deep-water family — the Bifaxariadse ; for although the Bicellariadse 
include many abyssal forms, one, Bugula (Halophila) johnstonice has usually occurred in 
comparatively shallow depths, whilst of the other two species, one, Cribrilina monoceros is 
very generally distributed in the southern hemisphere, and apparently occurs at various 
depths from 5 to 1350 fathoms; the fourth is too fragmentary to admit of complete 
diagnosis, but it belongs to the family Escharidse, and probably to only moderately deep 
water. 
“ It will be seen that by far the greater number of the deep-sea forms belong to families 
characterised by having the zoarium of great flexibility, rooted by a dense bundle 
of extremely delicate radical fibres, most of which are attached to separate Globigerince 
or other solid particles in the ooze or mud of which the bottom at these depths is usually 
formed.
