In this I muft agree with him ; becaafe his fir ft 
Coralline, which he calls Corallina Pavonia, is truly 
of that genus of plants: this mo ft elegant bucus I 
have particularly defcribed and figured (liffiy on. 
Corail. p. 88. T. 33. fig. c, d, e,)-, it is well known 
by the name of Turky- feather Fucus, and is called, 
in the Species Plant, p. 1630, Fucus Pavonius. 
What could have led Dr. Pallas into this miftake ? 
moft probably thofe beautiful farinaceous femi-circulai 
ftripes on it, which he muft have taken foi a lapi- 
defcent or calcareous fubftance ", one of the nroa 
diftinguifhing characters of a Coralline, even ac- 
cording to his own defcription of tnis genus. Il Ire 
had tried this farinaceous fubftance with an acid, he 
might obferve, that it would not ferment; it is of the 
fame nature with the farina that covers many plants, 
for inftance the Primula Auricula, and aimoft all the 
Lichenes foliacei and fruticulofi, or Liverworts. As 
to their fimilitude to the Conferva, tne conti ary will 
appear, as icon as I come to give the propei^ defini- 
tions to both thefe, and the Corallines. In tne faniu 
paragraph he fays, that the Corallines do not come 
near to any genus of Zoophytes. 
How far 'he is miftaken in this affertion, I will 
endeavour to prove from the following expeii- 
ments.
