Numerous specimens of this small species were obtained which do 

 not exceed 10 mm. in height. Some of the specimens give rise to one or 

 two pinnately-disposed branches. Gronangia are present on several of 

 the colonies. 



Bemarl-)>. — Tliis species appears in Whitelegge's list as N. solidida, 

 Bale. Owing to the extreme range of A^aiiation exhibited by the forms 

 distinguished as S. iudlvisa, S. solidula, and S. van\(bilif<, all three arc 

 now generally i-egarded as a single variable .species ; this must be known 

 as S. iHdivisa, which name appears Hrst in the publication.
