So many of the specimens of these curious pseudo-zoophytes procured 
during these researches were transmitted to Dr. Johnston for publication in 
his most valuable ‘ History of British Zoophytes,’ that the few memoranda 
made in the dredging papers of the more striking species at the time of 
capture, can give but little insight into their distribution. The following 
notes of depth may serve as contributions to future histories of them.
