in diameter and 4-0-4-5/^ in length in the minor branches. The 

 figures of F. Hillebrandii given by Bokghshn have no marked 

 difference from ours. Ile^^ states the slenderness of his specimen 

 when compared with the measurement given by Dk Toni for 

 F. Hillehrandii, and also tliat it agrees well with the sj)ecimens 

 from Bermuda Islands. Falkenberg'' remarks: — "Was die 

 specihschen Untersehiede der australischen Formen gegeniiber der 

 atlantiseh-mediterranen Art begrifft, so erscheint F. rufolanosa 

 den getrockneten Exemplaren nach als getreues, aber schlankeres 

 Abbild von F. Hillebrandii." I have paid special attention 

 respecting this point and can by no means be convinced by 

 Falkenberg's supposition. Whether the form under the present 

 species may vary in its thickness of filaments as tc^ approach 

 F. Hillebrandii or not, is a different question.

The specimen shows all characters of the 2nd. section ot 

 the genus. The ramulets are corticated at the septa and have 

 the apices spinulated. In some of them the spine is simple and 

 in others bifurcated. In the latter case the one which ter- 

 minates the ramulet is larger than the other in a lateral 

 position. Tetrasporcs are mostly found at the base of ramulets 

 as shown in Tab. Phyc. XII, Taf. 51, fig. G. 



Locality. Satsuma Prov. (Prof. vS. Ikeda). 



Distribution. West Indies; Atlantic coast of south-western 

 Europe; Mediterranenn sea; Red Sea.
