water. The other feems to be the fame with yours, 
and is, no doubt on it, Linnsus’s Pennatula Phof- 
phorea , fo that heconcludes them to be two diftindfc 
fpecies, and calls them by the following names, viz. 
Penna f Rubra J pinnis falciformibus , tentaculis in 
pinnarum facie concava denfiffime difpojitis. 
Penna ( Rofea ) pinnis falciformibus , tentaculis in 
pinnarum facie concava laxe difpoftis. 
In the three following chapters Dr. Bo- 
hadfch defcribes three other kinds of Sea-Pens. 
One he calls Penna Grifea or the Grey Sea-Pen 
with crenated fins ; this is figured and defcribed 
from a dry fpecimen in Seba’s Mufeum, Tom. III. 
The next is a very lingular one without fins, 
having a fquare bony ftem 2 feet 10 inches long, 
covered with a fkin, and furnifhed on 3 fides with 
tentacula or fuckers : but this was unfortunately 
broken off at the bottom before he received it : he 
fays, the fifhermen call it Penna del Pefche de Pa - 
vone , or the Feather of the Peacock- fifh. To thefe 
he has added the Alcyoniurn called, Manus marina ; 
he calls it Penna ramofa pi tints carens , tentaculis 
in ramis poftis y and in another place, Penna Exos. 
In order to give you and the reft of the Royal 
Society fome idea of thefe extraordinary Animals, 
I have copied his figures, and alfo the 'figures of the 
three laft fpecies of Linnasus’s Pennatula, viz. his 
Pennatula fFilofdj Pennatula (Sagitta) and Pen- 
natula f Mirabilis J from the authors which he refers 
us to, and have added an exadt delineation of our 
Alcyoniurn ( Manus marina J or Dead mans hand, with 
fome microfcopial drawings of different fedtions of 
it, to fhew that although the fubffance of it is 
flefhy, yet that it approaches much nearer to the 
Madre*
