464 DR A. MILNES MARSHALL AND MR G. H. FOWLER ON PENNATULIDA. 



Note. 



A species described as new by Professor Marshall (5), p. 129, under the 

 name of Virgularia tuber culata, appears on close comparison to be identical 

 with the Cladiscus gracilis of Koren and Danielssen (7), p. 101, pi. ix. figs. 

 13-15. The latter name naturally has priority, and V. tuberculata ceases to 

 exist as a separate species. At the same time we consider the generic 

 characters as given by the Norwegian authors too slight to justify a separation 

 of the form from Virgularia.
