A. JEJ. Verrill — Bermudian and West Indian Reef Corals. 161 



It is abundant both in shalloNV water and on the reefs at the Ber- 

 mndas. It also occurs even in Harrington Sound. It is still more 

 abundant on the Florida Reefs and throiighout the West Indies to 

 Colon, Columbia. A variety occurs at Pernambuco, Brazil. See 

 below, Revised List of Brazilian Corals. 



Quek'h (op. cit., p]). 181, 182) has recorded two of the forms 

 described by D. and Mich., as from the Cape Verde Islands. But 

 the identity of bis forms needs confirmation, by comparison of types. 

 The descriptions and figures of D. and M. are too poor for deter- 

 mination, 



I am not at all sure that all the forms described by Duch. and 

 Mich., and referred to this species by Vaugban, are one species, 

 though I have placed them among the synonyms on his authority. 

 If his opinion be correct, then this species is more variable in the 

 Antilles than it is at the Bermudas and Florida reefs, from whence 

 I have examined large series. 



There can be no doubt, however, that they have made too man}^ 

 species, b}^ far, in this group. I have seen only two or three forms 

 that could be recognized even as varieties, and doubt if more than 

 two massive species are included in their list, even if all be not forms 

 of P. astreoides. 



But I believe that Mr. Vaugban is wrong in uniting P. solida 

 \eY.=zP. VerriUii Rehb. to this species. Possibly he has not seen 

 the true P. VerriUii, for both species occur on the coast of Brazil.

Mr. Vaughan (op. cit.) considers this only a form of P. astreoides, 

 but as the latter occurs with it on the coast of Brazil, he may not 

 have studied a genuine example. I believe they are quite distinct. 

 I have, therefore, figured a portion of the original type. 



* The Porites solida (Forsk.)K]z., from the Red Sea, is a different, solid, 

 massive species, of which the Yale Museum now has an authentic example. 

 The use of the same name for the Brazilian coral was due to an oversight, on 

 my part, in overlooking Forskal's name, — not to any intention of uniting the 

 two species.
