The other 3 figures in this plate are introduced to 
(hew the form of the Pennatula referred to by 
Dr. Linnaeus, in his Syft. Nat. 10 Ed. 
p. 819. 
15. Is the Pennatula Ftlofa , and is figured in 
Boccone’s Recherches, pi. 287, pag. 287. This 
animal infefls the Xiphias or Sword-fifh in the 
Mediterranean-Sea by fucking their blood, and is 
called by Boccone, Hirudo cauda utrincpue pen- 
nata . 
16. Is the Pennatula Sagitta ; it is defcribed in 
Linnaei Amcenit’s Vol. v. Chin. Lagerftr. p. 
14. f. 3. and faid to infefi: the Lophius Hijlrio 
or Sea-Bat, in the Chinefe Sea. 
17. Is the Pennatula Mirabilis. This is called 
the Polypus Mirabilis , and is defcribed in the 
Mufeum of Adolphus Frederick King of Sweden, 
p. 96. t 19. f. 4. 
ftrong fifhy fmell : Yet I much doubt whether Sponges have fiich 
polype-iike fuckers a3 the Corals, Alcyonia, and Pennatulae, 
or are even produced by Worms, as the late ingenious Dr. Pey- 
fonel informs us j for in the title to the fecond part of his ma- 
nufcript on this fubjeit, which he dedicates to the Royal Society, 
he fays, that Sponges, as well as Corals, Madreporas, &c. are 
produced by animals that are of a particular fpecies of Urtica 
marina or Purpura ; but I am inclined to believe he took this for 
granted from the fimilitude they bear to Corals, Alcyonia, &c. 
rather than from adlual experiment. I rather take thofe holes, 
which I have obferved in them, to be fo many mouths upon the 
furface of the animal ; and I am the more inclined to believe it, 
from a remark I made with Dr. Solander at the Sea-Coaft of 
SulTex in the fummer 1762, on the Spongia Medullam Panis re - 
ferens , while it was in a glafs veflel of Sea-Water ; where we 
obferved, that the Mamillas that were on the furface opened and 
fhut, but that no fucker or animal-like figure appeared to come 
out.
