30 REPORT ON FORAMINIFERA AND OSTRACODA 



The example in the present series also reminds one of Bulimma contraria, Reuss, 

 sp., which differs, however, in showing " no real alternation of segments." * 



Genus — Virgulina, d'Orbigny, 1826 

 Virgulina schreibersiana, Czjzek (Plate II, Fig. 10) 



Virgulina schreibersiana, Czjzek, 1848, Haidinger's Naturwiss. Abhandl., vol. ii, 

 p. 147, PI. XIII, Figs. 18-20. H. B. Brady, 1884, Rep. Chall, vol. ix, p. 414, 

 PL LII, Figs. 1-3. Flint, 1899, Rep. U.S. Nat. Mus. for 1897, p. 291, PI. XXXVIII, 



Widely distributed both in the northern and southern hemispheres. Its bathy- 

 metrical range is from 10 to 3000 fathoms. A small example found, having the aboral 

 end acutely terminated. 



Virgulina subsquamosa, Egger (Plate II, Fig. 11) 



Virgulina subsquamosa, Egger, 1857, Neues Jahrb. fur Min., etc., p. 295, PI. XIII, 

 Figs. 19-21. H. B. Brady, 1884, Rep. Chall, vol. ix, p. 415, PI. LII, Figs. 7-11. 



This species, like the preceding, has an extensive geographical distribution, and 

 is found in soundings from shallow to deep water alike. 



A minute example occurs in the present collection. 



Sub-Family — Cassidulinin^e 



Genus — Cassidulina, d'Orbigny, 1826 



Cassidulina oblonga, Reuss (Plate II, Figs. 12a, \2b) 



Cassidulina oblonga, Reuss, 1849, Denkschr. Akad. Wiss. Wien, vol. i, p. 376, 

 PL XLVIII, Figs. 5, 6. C. crassa, d'Orb. (pars). H. B. Brady, 1884, Rep. Chall, 

 vol. ix, PL LIV, Fig. 4. C. oblonga, Reuss, Chapman, 1909, Sub- Antarctic Islands 

 of New Zealand, vol. i, art. xv, p. 332. 



This species is moderately abundant in the raised beach material. Its more 

 elongated test serves to distinguish it from C. crassa, with which it is often confused. 



C. oblonga has been dredged off W. Africa, off Cape Town, in the Mauritius, off 

 the West Australian coast, near Kerguelen Island, and north of Enderby Island in 

 the subantarctic group. Other localities might be cited but for the difficulty of 

 discriminating between references to this species and C. crassa. 



Cassidulina parkeriana, Brady (Plate II, Fig. 13) 



Cassidulina parkeriana, H. B. Brady, 1881, Quart. J own. Micr. Sci., N.S., vol. xxi, 

 p. 59. Idem, 1884, Rep. Chall, vol. ix, p. 432, PL LIV, Figs. 11-16. 



This is by far the commonest species occurring in the deposit. The series of 

 specimens selected from the washings shows all stages of the test from the sub-ovoid 

 to the distinctly crosier -shaped shell. The sutures are well impressed, and the aperture 

 is an elongate pyriform orifice. The majority of the examples, however, present the 

 appearance of Fig. 14 of the Challenger Report (loc. cit.). Hitherto the species has 

 occurred at three stations amongst the islands on the west coast of Patagonia at 

 depths from 45-175 fathoms.
