118 BULLETIN OF THE 



Antipathes humilis Pourt. 



Plate III. Figs. 18, 19, and 3». 



The most densely spinous species which has come under my observation. 

 Range from 76 to 262 fathoms, in four stations, off Montserrat, Grenada, St. 

 Vincent, and Barbados. 



There are several species described by Duchassaing and Michelotti, 

 and by the former alone in his Revue des Zoophytes et Spongiaires des 

 Antilles, Paris, 1870, which are too briefly characterized for identifica- 

 tion. The large species which I had formerly referred to A. dissecta 

 D. & M. is il. glaberrima Esper.
