to the generalization made by Professor Kolliker, in his report 
on the Challenger Pennatulacea, p. 38, that only the simpler 
forms of Pennatulacea occur in deep water, for our new genus 
is a very highly organized and specialized ‘form, of large size, 
with complex lateral groups of very large polyps. But our 
two species of Pennatula(P. aculeata and P. borealis) both 
range downward to 1255 fathoms, and the generalization re

American coast, were taken this year in 1054 to 1060 fathoms. 
Two of these were of very large size. Curiously enoug 
another species of this genus was obtained at about the same 
time by one of the Gloucester fishing vessels off Nova Scotia 
and was sent to the Fish ee ing at Wood’s Holl by Capt 
J. W. Collins. This is a very large and handsome species
