Three of the species recorded by Duncan from Antigua, in my 

 opinion, are incorrectly identified and their names are dropped 

 from the list. They are as follows: 



Favoidea jungJiuhni Reuss, according to Duncan. 



Heliastraea barbadensis Duncan. 



Solenastraea luronensis (Michelin), according to Duncan. 



Another species, Astraea megalaxoria Duncan, is based on uniden- 

 tifiable material, and its name is also dropped. The total number 

 of recorded species from Antigua, therefore, is 69, and 5 varieties are 

 recognized. Of the 33 species indicated as new, descriptions of 8 

 have been written and descriptions of 26 remain to be written at 

 the time of making out the preceding table. 



The number of species, 69, recognized is interesting for compari- 

 son with the number recorded for areas in which living reefs occur. 

 Von Marenzeller 1 records 71 species from the Red Sea in his report 

 on the Pola expedition corals Bedot 2 records a total of 74 species 

 + 5 varieties from Amboina — a number that should be reduced by 

 about 4, because of the reference of some names to the synonymy of 

 other species listed, leaving the number of valid species at about 70. 

 In my paper on the shoal-water corals from Murray Island, Austra- 

 lia, I list 63 species from Murray Island and its vicinity in water 

 not exceeding 18 fathoms deep, and report 51 species from Cocos-
