On the other hand, its bright colour will make it be easily 
detected, when specially sought for. 
By comparing the figure now given with that of Bangia cera- 
micola (Plate CCCXVIL.), the differences between these species 
may readily be seen; differences which preclude us from re- 
garding them as states of the same plant, as Kiitzing supposes. 
Possibly that acute author, not havig seen any specimen of 
our British plant, first described by Capt. Carmichael, has 
mistaken some other plant for it.
