Zoarium forming large tufts of dichotomously divided branches. 

 Internodes of moderate length, slightly arcuate, almost entirely 

 occupied on one side by a biserial cluster of 6-9 pairs of zocecia, 

 which usually slightly diminish in height from the proximal to 

 the distal extremity.

"When I previously described this species as A. inarmata T had 

 not seen Krauss' work, and could not procure a copy of it. 

 After seeing his description and figure, I am satisfied that the 

 Australian and South African species are identical. The amount 

 of curvature of the internodes varies, some being almost straight. 

 From A. Brogniarfii, it differs in the ai'ching and shortness of 

 the internodes, and the small number of zocecia, and from 

 A. JVoodsii in the absence of the confervoid filaments, the 

 smaller numl)er and greater thickness of the zocecia and their not 

 diminishing in size distally in the very marked manner they do 

 in the latter species. 



ft With filamentous or confervoid appendages.
