224 AKTHUR EARLAND ON THE FORAMINIFERA OF 



Discorbina tuberculata, Balkwill <fe Wright. 



Discorbina tuberculata, Balkwill & Wright, 1885, Trans. R. Irish 



Acad., vol. xxviii. {Science), p. 350, 

 pi. xiii., figs. 28 — 30. 

 A single weak specimen found by Mr. Wright. 



Discorbina vesicularis, Lamarck, sp. 



JJ/scorbites vesicularis, Lamarck, 1804, Ann. Mils., v., p. 183 ; 



and/. 7, pi. 62, viii., 1806. 

 Discorbina vesicularis, Brady, 1884, Report " Challenger" p. 651, 



pi. lxxxvii., fig. 2, a, b, c. 

 ., ,, Halkyard, 1889, "Recent Foraminifera of 



Jersey," Trans. Manchester Mic. Soc, 



1889, p. 15, pi. ii., fig. 8. 



Frequent. Not previously recorded in Great Britain. The 

 specimens are very small compared with those found in Australian 

 shore-sands ; but they are quite typical, and the asterigerine fiaps 

 are well developed. (Plate 12, Figs. 9 and 10, and Plate 14, Fig. 6.) 



Halkyard's specimens from the shore-sand of St. Catherine's 

 Bay, Jersey, must have been identical with the Bognor specimens, 

 to judge by his figure. Mr. Wright informs me that he has met 

 with the species in shore-sand from North Donegal (rare) ; also 

 at Rockfort, Belfast Lough, between tides, where it was 

 abundant. Mr. Millett has also found it on the south coast of 

 England. 



Discorbina turbo, d'Orbigny. 



Rotalia (Trochidina) turbo, d'Orbigny, 1826, Ann. Sci. Nat.^ 



vol. vii., p. 274, No. 29 ; Modele, 

 No. 73. 



Discorbina turbo, Brady, 1884, Report " Challenger" p. 642, 



pi. lxxxvii., fig. 8, a, b, c. 



Two specimens (one attached) were found, which are probably 

 referable to this species, which does not appear to have been 

 previously recorded in Great Britain. Mr. Wright, on examining 

 them, wrote : " Your specimens, I think, come nearer to turbo 

 than anything else. At the same time, it might be advisable to 

 mark it with a query, as the specimens are not sufficiently typical 

 to name with certainty."
