I should think that the fragment figured in Van Heurck's Synopsis 

 as Actiniscus pennatus, is the same form as known as Corethron hispi- 

 dum Castr. (inch C. Murrayanum which only differs from the typical C. 

 hispidum in the smooth valves), and consequently the name pennatus has 

 the priority.
