BULIMININAE 353 



At these stations, typical specimens of the original compressed type of Egger occur. 

 His records are mainly from the South Pacific Ocean. 



141. Virgulina bradyi, Cushman. 



Virgulina subsquamosa, Brady (non Egger), 1884, FC, p. 415, pi. lii, figs. 9 a-c (? 7, 8). 

 Virgulina bradyi, Cushman, 1918, etc., FAO, 1922, p. 115, pi. xxiv, fig. i. 



Seven stations: 236; WS 77, 86, 221, 248, 408, 433. 



Moderately common. Cushman has separated the sub-cylindrical and few-chambered 

 forms figured by Brady {lit supra) from the compressed and more regularly disposed 

 type originally figured by Egger {ut supra, No. 140) on what appear to be sufficient 

 grounds, as the two forms do not always occur in company in our material. 



Genus Spiroplectoides, Cushman, 1927 



142. Spiroplectoides rosula (Ehrenberg) (Plate IX, figs. 5, 6). 



Spiroplecta rosula, Ehrenberg, 1854, AI, 11, Index, p. 24, pi. xxxii, fig. 26. 



Textularia complexa, Brady, 1865, RFND, p. loi, pi. xii, fig. 6. 



Spiroplecta demersa, Ehrenberg, Abh. k. Ak. Wiss. Berlin, 1872, p. 294; 1873, LMT, p. 391, 



pi. vii, fig. 26. 



Spiroplectoides rosula, Cushman, LFR, 1927, ni, p. 114, pi. xxiii, figs. 6, 7. 



One station: WS408. 



Several good specimens. The records of this species are very few, but the discovery 

 of specimens in such a distant locality as the Falkland Islands may indicate that it is 

 widely distributed, and that its very minute size may be the reason for the paucity of the 

 records. We give S. demersa as a synonym doubtfully ; the construction of the shell is not 

 given by Ehrenberg, though the colour is stated to be yellow, suggesting an arenaceous 

 shell, but the figure is clearly hyaline. The identity of Textularia complexa is also not 

 above suspicion if the dimensions given by Brady (length ^ inch) are correct. S. rosula 

 is only about one-third of this length. 



Genus Bolivina, d'Orbigny, 1839 



143. Bolivina punctata, d'Orbigny. 



Bolivina punctata, d'Orbigny, 1839, FAM, p. 63, pi. viii, figs. 10-12. 

 Bolivina punctata, Brady, 1884, FC, p. 417, pi. lii, figs. 18, 19. 



Twenty-two stations : 48, 228, 236 and WS 71,77, 78,79,83,86,88,89,90,92, 93,97, 215, 217, 

 221,245,248,408,433. 



Universally distributed, often very common. Both megalo- and microspheric forms 

 are represented, the best specimens at 236 and WS 83, 93, 217, 221 and 408. At some 

 of these stations, the specimens are very large and remarkably hyaline. The Paris 

 "Amerique meridionale" Type tube contains only a single small specimen: it is quite 

 opaque and the punctation is consequently not obvious, but it agrees on the whole with 

 his figure.
