to the kindness of M. Lenormand, who procured them at Gran- 
ville, on the French coast, where Codium Bursa is common. 
The station on the Sussex coast, quoted from Pallas, is not pro- 
lific in modern times, nor have I ever seen any British specimen 
except a small one obtained by Mrs. Griffiths, in Devonshire. 
No one has met with this plant near Belfast but Mr. Templeton, 
and I have not seen his specimens.
