The spicula of this species resemble most those of IF. tubigera., but 

 while the branches are much smaller, the spicula are absolutely much 

 larger. They are also rougher, with larger spinules, and the small 

 spicula are much less abundant and more regular in form. Its thin 

 canienchyma, and long, clavate, tubular cells, with slender projecting 

 spicula, will at once separate it from all other species, except, perhaps,

 cylindratis, obtusis. Ca-nenchyma sjiiculis iiisiformibus, verrucosis, 

 fulvis suflultum." 



This species, as described and figured by Mobius, forms an openly 

 and loosely branched corallum, with slender divergent branches, cov- 

 ered with loosely arranged, tubular, and somewhat clavate verrucse, 

 which are obtuse or truncate and eight-rayed at summit, the sides and 

 upper margin with a few slightly projecting points of long and large 

 spicula. The ccenenchyma is thin and the verrucse are about equal in 

 length to the diameter of the branchlets and smaller branches. The 

 long spindles are stout fusiform, with distantly arranged, rough, une- 

 qual warts. The two figured would measure I •45'""^ by -30""", and 

 1-07 by •23.

Corallum dichotomous, the branches subdividing two or three times, 

 branching nearly in a plane. The trunk usually divides close to the 

 base into two or more main branches, each of which usually forks 

 again within half an inch. Some of the central secondary branches 

 rise nearly perpendicularly and do not subdivide for one or two inches, 

 or even more, but the outer ones often fork two or three times more, 

 at distances of about half an inch. The terminal branches and branch- 

 lets are from one to four inches long, round, subparallel in large speci- 

 mens, tapering but little, usually obtuse at the ends, and nearly as 

 large as the main branches. The branches usually spread at a large
