54 Vaughan — Nomenclature of West Indian Corals. 



Corals of the Porto Rican Waters",* I attempted to determine 

 the proper names so far as the material included in those re- 

 ports seemed to justify, and made many changes. Prof. A. E. 

 Verrill has written an extremely valuable paper, "Variations 

 and Nomenclature of Bermudian, West Indian, and Brazilian 

 Reef Corals, with Notes on Various Indo-Pacitic Corals", f now 

 appearing, treating of the same subject. In this paper some 

 additional changes are made. In the paper just mentioned and 

 in a review of ray "Stony Corals of the Porto Rican Waters", J 

 Prof. Verrill has given reasons for dissenting from some of 

 the conclusions reached by myself, and as we had had an ex- 

 tended corresi^ondence concerning the differences between us, 

 he inserted a foot-note stating wherein I agreed with him after 

 further consideration. 



Too many changes have been made in the nomenclature for 

 all of them to be i-eviewed here, but as it seems desirable that 

 the following additional data, largely of a bibliographic nature, 

 be laid before the students of stony corals the following notes 

 have been prepared. The names discussed are those used by 

 Prof. Verrill in his memoir cited above and in his review of my 

 Porto Rican corals in place of the ones used by myself. In 

 tabulating the following notes the name employed by Prof. 

 Verrill is placed first, versus the one employed by myself, 

 which is placed second. Five cases are discussed, in three of 

 which Prof. Verrill and I agree, but in the remaining two we 

 still hold different opinions. 



1. Acropora, Oken, 1815, versus Isojwra, Studer, 1878. I 

 overlooked the availability of Oken's Acropora, for the La- 

 marckian, not Linnean, JIach'epora. Prof. Verrill is correct, 

 Acro2)ora is the proper generic name. 



2. Maeandra, 1815, versus Platygyra, 1834, 3fanicina (areo- 

 lata as type), 1834, and Diploria, 1848. I selected as the type 

 of Maeandra the species figured by Oken, the maeandrites of
