 Akock in his Deep Sea Madreporaria of the Siboga Hxpedition, p. 85, lists some 

 "fine specimens" as 'M. minen Mueller sp." 



in this connection the availaltility of the speciti • name rainea should l)e considered. 

 O. F. Midler in liis /oologia' Danica- Prodroums, ITT*!, p. 2.52, cites under Mndn'pora, 

 M. ramca, and credits it to Linnaeus, Systema Natune, 12th edition, 1707. The 

 Mudrepora rumeii Limueus, 1758, Is according to subsequent authorities the Den- 

 drophijUiaramea (Limneus) Blainville, of the Meditei'ranean. Linnseus in his original 

 description of Miidnpora ramea refei's to twt) previously published figures, one by 

 Petiver which I iiave not seen, the other by Marsigli,' which I have seen. The latter 

 reference is given by Milne Edwards and Hainie in their synonymy of the species, 

 and represents the conunon I)<mdroph>/Uia ramea. There is no reason to doubt the 

 correctness of the identification of Pallas, Ellis and Solander, and Milne Edwards and 

 Ilaime. It seems that Midler never proposed 2tadrepora ramea as a new specific 

 name. If he had, his name would be a homonym of the previously established 

 Madrepf/ra ramea Linnauis, and therefore invalid.' 



The I)lphdii'I!a]>rofirnda Pourtairs is an Eupsannnid coral and not a Dipltdtelia, 

 as Pourtales himself discovered and published in lfS78. Should the other forms cited 

 by Duncan under the synonymy of Dlphdielia ram<-a really belong together, as 

 he contends, the name would be Madrepora miorenica (Seguenza), but Duncan's 

 discussion of the forms is not satisfactory, and until someone carefully studies the 

 Porcupine collection and makes comparisons with Italian Tertiary material, it is not 

 possible to reach any decision regarding the affinities of the recent species to those 

 from the Tertiaries of Italy. 



Duncan in his article in the eighth xoiumc of the Transactions of the Zoological 

 Society of London, redefines the genus ^l///y>/(//)(^//(^, stating that "'the coi'allites do 

 not fill up from below." I have looked the matter up on specimens of .1. neulata 

 and find that the corallite cavities in their lower portion may be practically obliterated 

 by stereoplasmic d(>i)osif. 



The coral that I am here denominating Madrejjora hiua/'ensifi apparently ditiers 

 from the material that Duncan had by having the bottoms of the corallite cavities
