of the species. In his ' Revision ' Duncan seems to have been puzzled 

 by this group of species, and left three of them in Plesiastrcea, 

 apparently with considerable hesitation. For the fourth he pro- 

 posed the genus Antillastrcea. I can see no difference whatever 

 between this and Steplianoccenia, and feel no doubt that had Prof. 

 Duncan compared the two he would have recognized their identity ; 

 but, as he placed them in different alliances, he probably did not 

 compare them. 



Plesiastrcea globosa, Duncan, is a Leptastrcea, and is probably 

 L. caribcea, Duch. & Mich. ; P. ramea, Duncan, appears to me to be 

 an Orbicella, as the structures regarded by Duncan as pali are 

 probably only paliform lobes.
