188 ARTHUR EARLAND ON THE FORAMINIFERA OF 



absolutely exhaustive. Probably a local rhizopodist would be 

 able to add many species to it by varying his methods of 

 collecting and extending the area of research, as the whole of 

 my material was obtained from about fifty yards of the foreshore 

 between tide-marks. 



The gathering is primarily a Milioline one. The genus 

 Miliolina in various species occurs in an abundance quite out 

 of proportion to other forms, and gives a characteristic por- 

 cellaneous appearance to the coarse material. The finer material 

 is, however, very varied in the character of its contents, and 

 is principally responsible for the very long list of species 

 observed. 



The total number of species identified, exclusive of a few 

 doubtful forms, is 140, and is made up as follows : — 



Miliolidae . . 28 Lagenidae . . 38 



Astrorhizidae . 1 Globigerinidae . 3 



Lituolidae . .10 Rotalidae . . 28 



Textularidae . 24 Nummulinidae . 8 



Many of the species now recorded are of very rare occurrence 

 in Great Britain, and, in addition, the list contains one new 

 species, Spiroplecta fitsca, and one new variety, Massilina secans, 

 var. tenuistriata. There are also the following species, 15 in 

 number, which, to the best of my knowledge, have not previously 

 been recorded in Great Britain : — 



Sjnroloculina antillarum, d'Orbigny. 



Sigmoilina costata, Schlumberger. 



Massilina secans, d'Orbigny, var. denticidata, Costa. 



Gaudryina subrotundata, Sch wager. 



Bolivina tortuosa, Brady. 



,, 7iobilis, Hantken. 

 Lagena stelligera, Brady. 

 Nodosaria soluta, Reuss. 

 Cristellaria acideata, d'Orbigny. 

 Polymorphina regina, Brady, Parker & Jones. 

 Uvigerina porrecla, Brady. 

 Discorbina vesicidaris, Lamarck. 

 Anomalina grosserugosa, Giimbel. 

 Pulvimdina hauerii, d'Orbigny. 

 liotalia calcar, d'Orbigny.
