the quill to the extremity : from each fide of this 
upper part of the ftem proceed little parallel fea- 
ther- like fins; thefe begin at the top of the quill 
part, very fmall on each fide at firft, but lengthen 
as they advance towards the middle; from hence 
they fhorten gradually on each fide, till they end at 
a point at the top ; their terminations preferving 
on each fide the figure of the fegment of a circlet 
I come now to confidermore minutely thofe Pinnulse, 
or feather-like fins, that projedt on each fide and 
form the upper part of this animal. Thefe are 
evidently defigned by nature to move the animal 
backward or forward in the fea, confequently to do 
tne office of fins, while at the fame time, by the 
appearance of the fuckers or mouths furnifhed with 
filaments or claws, they were certainly intended to 
pi ovide food for its fupport ; for notwithstanding 
what Dr. Linnaeus has faid in regard to its mouth 
in his fyftem of nature, viz. Os bafeos commune ro~ 
tnndum , I could not, with the help of the befl 
glaffies, difcover that the point of the bafe was pene- 
tiated in the lead, fo that I am. clearly of opinion, 
that this animal, like the Hydra Ardtica or Green- 
land Polype, which I have defcribed in my Effiay on 
Corallines, nouriffies and fupports itfelf by thefe 
fuckers or Polype-like figures; that by thefe, both, 
kinds taKe in their food, and have no other vifible 
means of difcharging the exuviae of the animals 
they feed upon, than by the fame way which they 
take them in ; and that, from attentively confiderino- 
the ftrudlure and manner of living of both thefe' 
animals, I ffiall make no doubt in claffing them in 
the fame genus of Pennatula, though they vary
