240 MESSES. E. HERON-ALLEN AND A. EAELAND ON THE 



141. Bolivina tortuosa, Brady. 



Bo/ivbia tortuosa, Brady, 1879, etc., RRC. 1881, p. 57. 



„ „ Brady, 1884, PC. p. 420, pi. lii. figs. 31-34. 



2 Stations. 



A single specimen, referable to Brady's species, at Stns. 4 and 6. The question of the 

 specific value of this so-called species is very doubtful. Tortuose specimens clearly 

 referable to other species, such as B. dilatata and B.eenariensis, occur in the dredgings. 

 This species has only been recorded as a recent British form by ourselves (H.-A. & E. 

 1908, etc., SB. 191.1, p. 317; and 1913, CI. p. 66, pi. v. fig. 1). 



142. Bolivina plicata, d'Orbigny. 



Bolivina plicata, d'Orbigny, 1839, FAM. p. 62, pi. viii. figs. 4-7. 

 Goes, 1894, ASF. p. 51, pi. ix. figs. 487, 488. 



23 Stations. 



Almost universally distributed, generally common. Good typical specimens at most 

 Stns., the best at 4, 9, 10, 16, and 20. There are, as usual, at most Stns. a number of 

 specimens intermediate between this species and B. variabilis. 



143. Bolivina variabilis (Williamson). 



Textularia variabilis {typica), Williamson, 1858, RFGB. p. 7o, pi. vi. figs. 162, 163 (not 161 & 162). 

 Bolivina variabilis, Heron-Allen & Earlaud, 1913, CI. p. 68. 



20 Stations. 



Generally distributed, often abundant. This not very satisfactory species is, as usual, 

 subject to great variation, the specimens running in a more or less complete series 

 between B. plicata and B. punctata. 



141. Bolivina illflata, Heron-Allen & Earlaud. 

 Bolivina infiata, Heron-Allen & Earland, 1913, CI. p. 68, pi. iv. figs. 16-19; 1915, FKA. p. 648. 

 9 Stations. 



Poorly represented, the specimens being few and not very typical, the best at Stns. 11 

 and 18. This species, first recorded by us nt supra, is probably widely distributed. 



Subfamily Cassoulinina 

 Cassidulina, d'Orbigny.

Cassidulina laevigata, d'Orbigny, 1826, TMC. p. 282. No. 1, pi. xv. figs. 4, 5, Modele No. 41.

Almost universally distributed. At all the Stns. but four where the species was
