31 8 Wright — Foraminifera of Down and Antrim. 



no doubt, is the reason why so few additions to the Foraminifera of our 

 North-East Coast were obtained from the "Protector" gatherings. S. M. 

 Malcomson, M.D., had also made a most exhaustive search for Foraminifera 

 in shore sand and rock pools in the vicinity of Rockport, Belfast Lough. At 

 this place he found 87 different species, two of them — viz., Spiroplecta 

 biformis and Placopsilina cenomana — being new to Britain. At my request, 

 Dr. Malcomson very kindly furnished me with a list of the species which he 

 had found, and also their relative abundance. I have given the record of his 

 discoveries in Column 5 of the table of geographical distribution. 



For the sake of completeness, I have given in the last column a list of the 

 Foraminifera recorded in my former paper (loc. cit.),* and at the end of the 

 table the names of three species which had not been met with in either the 

 "Protector" gatherings or at Rockport. The present list, therefore, com- 

 prises all the species that are now known from this part of our coast. t 



In conclusion, I have to thank Mr. H. B. Brady, F.R.S., for his kind 

 help and advice in the identification of some of the critical species. I am also 

 much indebted to S. M. Malcomson, M.D., for the very accurate and artistic 

 drawings which accompany this memoir.

 Club, app. 1876-7. 



+ Of late years our increased knowledge of Foraminifera has necessitated many 

 changes both in the names of the genera and species, and, in consequence of these altera- 

 tions, a number of the species given in my paper on Foraminifera of Down and Antrim 

 (1876-7) are now known by other names. The following is a list of the species which 

 have been so altered, the names by which they had been recorded being given in italics. 

 I have not , however, thought it necessary to note any changes which may have been made 

 in the generic names, as such will be sufficiently obvious to the reader. 



Comuspira involvens, Hs.—Cornuspirafoliacea, Phil. 



Haplophragmium pseudospirale, Will.— Lituola nautiloidea, Lamk. 



Bolivina dilatata, Rs.= Textularia pygmcea, d'Orb. 



Lagena lineata, "Will. =Lagena caudata, d'Orb. 



Lagena aspera, Ess. =*Lagena hispida, Ess. 



Lagena hispida, Hss.=Lagena Jeffreysii, Brady. 



Lagena laevigata, Ess. =Lagena lucida, "Will. 



Lagena lagenoides, Will.— Lagena yrnata, "Will. 



Marginulina costata, Ba,tsch.=DentaIina obfiquestriata, Ess. 



Polymorphina gibba, d'Orb., fistulose iorm^-Polymorphina Orbignyi, Zbor. 



Gypsina versicularis, P. and Z.—Tinoporu& Isevis, P. and J. 



Gypsina inhserens, Schultze. =Tinoporus lucidus, Brady MS. 

 The following names have been excluded from the present memoir, as they are not 

 now considered good species, viz. :- Biloculina elongata, d'Orb; Spiroloculina canalicu- 

 lata, d'Orb. ; Triloculina Brongniartii, d'Orb. ; Lagena Lyellii, Seg.; Lagena trigono-margi= 

 nata, P. and J. ; Lagena oblonga, Seg. ; Dentalina guttifera, d'Orb. ; Textularia variabilis, 

 "Will. ; and Discorbina ochracea, "Will. I have also thought it best to omit the following, 

 as the specimens found were not typical, and, in consequence, their identification not as 

 reliable as could have been wished, viz. :— Miliolina agglutinans, d'Orb. ; Textularia 

 trochus, d'Orb. ; Lagena distoma, P. and J. ; Lagena gracillima, Seg. ; and Nodosaria 

 raphanus, Linn.
