Siphonogorgia asperula, n. sp. 



To this new species we refer two colonies which, though differing in certain 

 respects, e.g., the grouping of the verrucse, and in the details of the spicules, yet 

 present certain well-marked affinities, e.g., the architecture of the anthocodiaj. 

 The essential specific distinctions as well as the differences inter se may best 

 be summarised in a table.
