The individual are conical or dome-shaped, a typical one measuring 1 mm. in

and the tentacles are heavily armed with spindles which are arranged en chevron on the

Spicules. The superficial spicules of tin- coenenchyma are oval, very densely tuber- 

 culate forms, th'- real surfaces being concealed by the crowding of the tubercles. Under these

This handsome species is quite different in habit from any other of the genus in the 

 collection.

and posterior faces of all branches. The specimen is 46 cm. high and has a spread of about 



50 cm. The main stem forks 4.2 cm. above its base and is very strongly laterally compressed, 



having a cross section of 2.3 cm. v 1.2 cm. The two main branches are directed outward and 



then curve upward and their basal parts are very strongly laterally compressed, further out 



they become round and their distal portions are flattened. They are irregularly enlarged in 



-, the enlargements being due to symbiotic barnacles. The main branches give off a few 



short branchlets from their lower sides and a number of branchlets, both simple and compound, 



fnun their upper sides -. and these give off lateral branchlets until branchings of the 6 rt order 



attained. The distance between branches, as well as their arrangement, is very irregular.

The individual calyces are quite low verrucae on proximal parts (although more prominent
