No. 2] NOTES ON TWO LITHOTHAMNIA FROM FUNAFUTI. 



somewhat stunted form of L. Philippii. It vvill be pictured on a 

 SLibsequent occasion. 



The other specimen mentioned is according to the label from 

 .,the Consolidated Rock, forming platform Hurrican Beach, Funa- 

 futi". Also this specimen has stucls; to corals. It is infested with 

 some fragments of green algae showing that it has grown in the 

 litoral or uppermost part of the sublitoral region, as the labels 

 appears to indicate. It is to be referred to 



Goniolithon oncodes (Hej^dr.) Fosl. 



The specimen agrees in habit with that species, the longest 

 diameter being about 5.5 cm., but the thickness rather var^dng and 

 apparently not exeeding 7 mm., with a smooth surface or nearty 

 so. • It is somewhat sparingly furnished with conceptacles of 

 sporangia about 200 jj- in diameter. 



This specimen corresponds with the said species also in struc- 

 ture except that the perithallus is not so continuous as in typical 

 specimens, but gets here and there overgrown with a new and 

 irregular hypothallus, which, however, as a rule is due to external 

 circumstances. Therefore the structure is less regular than in the 

 typical form. Besides being quite burdened with inferior animals, 

 especially with numerous passages produced by worms, the plant 

 is in part interpenetrated with perforating green algae.
