When well grown this is one of the most elegant corals of these 
waters. It grows taller, with a stouter trunk than the last, and 
branches more sparingly and in a more tree-like manner, with stouter 
and longer branches. The calicles are larger and more prominent

and much swollen at base, or even mammiform, and on the large 
branches are often surrounded by a depression and ridge. The 
coral, when dried and bleached, becomes pure white, but in life it is 
usually light yellow. The polyps are translucent and rise much 
above the calicles in full expansion. The tentacles are slightly 
knobbed at the tip and specked with white.

These Trans., xi, p. 175, pl. xxx, fig. 3, 1901. 
This singular variety has the corallets much more elevated, swollen 
or mammiform at base, with the calicles smaller than usual. The 
surface is nearly smooth. It is rather rare. The best examples that 
I have seen were from deep water in Harrington Sound.
