Lagena hexagona, Williamson sp. 



Entosolenia squamosa, var. hexagona, Williamson, 1848, Ann. 



and Mag. Nat. Hist., ser. 2. vol. i, p. 20, pi. ii, fig. 23. 

 Lagena hexagona, Williamson sp., Millett, 1901, Journ. E. 



Micr. Soc, p. 8. 



A single typical specimen of this elegant form occurs in our 

 material. 



Lagena lacunata, Burrows and Holland. 



Lagena lacunata, Burrows and Holland, 1895, in Jones's 



Palseont. Soc. Mon., Crag. Foram., pt. ii, p. 205, pi. vii. 



fig. 12. 



This species is distinguished from the better-known L. 

 castrensis, Schwager, by the depressions on the faces of the 

 test. Millett regards both of these forms, perhaps rightly, as 

 one variety of L. orbiguyana. 



L. lacunata is not uncommon in our soundings. 



Subfamily Nodosariin2E. 



Genus Nodosaria, d'Orbigny. 



Nodosaria hispida, d'Orbigny. 



Nodosaria hispida, d'Orbignv, 1846, Foram. Foss. Vienne, 

 p. 35, pi. i, figs. 24, 25. Egger, 1899, Abhandl. k. bayer. 

 Akad. Wiss., cl. ii, vol. xxi, p. 79, pi. ix, figs. 23, 24. 



This is a very variable form, the only constant character 

 being the hispid surface of the test. 



A single specimen was found off Great Barrier Island, 

 which consists of two closely conjoined chambers with short, 

 coarse prickles. 



N. hispida has been met with in the South Pacific, but not 

 very near the present locality. 



Nodosaria pyrula, d'Orbigny. 



Nodosaria pyrula, d'Orbigny, 1826, Ann. Sci. Nat., vol. vii, 

 p. 253, No. 13. Flint, 1899, Bep. U.S. Nat. Mus. (1897), 

 p. 309, pi. lv, fig. 4. Millett, 1902, Journ. R. Micr. Soc, 

 p. 514. * 

 Three specimens of this sparingly distributed form occur 



in our series. In each case the last chamber of the test is 



seen to contain a reddish-brown substance which is probably 



of the nature of dried protoplasm. 



N. pyrula has been recorded from various observing- 



stations in the South Pacific, but not from the present 



locality.
