ANTIPATHA.EIAN CORALS OP MADEIRA.

scattered microscopic hairs, which are seated on thick bases aud 

 taper to a fine point. They sometimes fork near the tip (fig. III. B). 



A single specimen has been in my possession for many years. 

 It is without a base, and may possibly be only a branch of the entire 

 corallum. It has a length of about 205 millim. (8 inches) and 

 measures 180 millim. (7 in.) through. 



Should other specimens occur, a careful examination of them 

 might lead to the conclusion that this form is entitled to rank as 

 a species.
