more robust is characterised by alternate pinnae. The cysto- 

 carps of E. Fergusonii are borne at the apices of special short 

 branches (modified pinnae), and by this character the plant is 

 separated from Rhodocallis, Kiitz.

One of Wright's original specimens exists at Kew, given by 

 Harvey to Hooker. An examination of this specimen was thought 

 to be advisable with the object of verifying the supposition of 

 Okamura, as to the genus in which the plant should be placed. 

 I he examination proves Okamura to be right, the structure of the 

 trond being that of Grateloupia and not that of Gigartina. 



Explanation of the Plate. 



All the figures refer to Euptilota Fergusonii, Cotton. 



I ig. 1 . Apex of a main branch showing arrangement of pinnae and 



pmnnlae. The pinnae (/>.) are alternate and bear pinnulae (pi.) 

 on both their upper and lower surfaces. Those pinnulae from 

 the lower surface arise first (pi. 1), those from the upper surface 

 appear later Qrf.2); the pinnulae from the upper surface arise 

 only from the two lowermost cells of the pinnae. The corticating 

 filaments (c./.) are also shown, x 180.
