The individual calyces are about 4 mm. high and 1.5 mm. in diameter. They are strictly 

 tubular, enlareinof somewhat toward their summits. Their walls are rilled with heavy tuberculate 

 spindles irregularly disposed, but tending to be vertical. There are eight marginal points, 

 formed by the main opercular spindles which are more slender than in A. aurca. They are 

 formed by two large spindles with their proximal ends divaricated and their distal ends approximated. 

 A third spindle is laid across outside of the basal ends of the two already mentioned. Below 

 these the polyp is surrounded by a circlet, more or less incomplete, of spindles. There seem 

 to be two layers of spindles in the calicular walls and ccenenchyma, but they do not imbricate. 

 The marginal points of the calyx project well above the folded tentacles, which do not form 

 an elevated dome, as in the next species. 



S p i c u 1 e s. The spicules are all rather stout, gently curved and tuberculate spindles, 

 with the tuberculations not very close. 



C o 1 o r. The colony is light brown throughout, without any golden or orange tinge. The 

 spicules are colorless.

Colony flabellate in form, attaining a height of 24 cm. and a diameter of 15 cm. The 

 main stem has a diameter of 4 mm., and branches about 3 cm. from its base. The branches 

 are irregularly alternate, and the branching continues until branches of the fifth order are 

 produced. There are no terminal calyces; but they are lateral in position, and tend to be 

 subopposite. Sometimes, however, there is a tendency to form spirals of three, particularly on 

 the distal branchlets. The calyces on a given side are not in the same plane, but are inclined 

 alternately to the front and back of the stem or branch. They are very irregularly spaced, but 

 are usually rather distant, those on a given side being from 1.5 to 4 mm. apart. 



The individual calyces are cylindrical in form, and are often curved. A typical one 

 measures 4 mm. in length, and 2 mm. in diameter, and is of nearly the same diameter 

 throughout. Their walls are filled with large fusiform spindles irregularly disposed, but most 

 often lengthwi.se. On the margin there is a series of eight blunt points, each corresponding to 

 a tentacle base. The retracted tentacles form a dome-shaped mass resting within the margin. 

 The upper surfaces of the tentacles are filled with small spindles arranged en chevron, and 

 the collaret is inconspicuous, represented by an ill defined ring of slender spindles. 



Spicules. These are all large, stout, straight or curved, very warty spindles. The 

 tubercles are thickly and evenly packed on the surface, but are small. Those on the stem and 

 branches are longitudinally disposed. 



Color. The colony is a rather bright orange brown, the calyces being somewhat lighter, 

 and the stem darker. Many of the spicules are of this golden or orange color.
