FOEAMINIFERA— HERON-ALLEN AND EARLAND. 227 



Very rare, but good specimens at the early N.Z. Stations. Very niinute at 

 Stations 8 and 10. A single individual at Station 54. 



612. Nonionina stelligera, d"Orbigny. 



Nonionina stelligera, d'Orbigny, 1839, FIC. p. 128 pi. iii, figs. 1, 2. 



Heron-Allen and Earland, 1916, FWS. p. 280, pi. xliii, figs. 8-10. 



Stations 3, 6, 7, 9-11, 26, 27, 31, 38, 45, 46, 48, 50, 53-55 (+D.). 



Universally distributed, except at the deep-water Stations. Best at Stations 

 7 and 10 in the N.Z. area, and at Stations 27, 31, 38 and 50 in the Antarctic. 

 This is a typically Arctic species so far as records go, and its occurrence in 

 similarly high Antarctic latitudes is noteworthy. It is probably the most abundant 

 representative of the genus in the Antarctic, and a similar prevalence occurs in 

 Arctic dredgings from Iceland w^hich we have examined. Extremely rare in 

 temperate tropical seas. 



613. Nonionina umbilicatula (Montagu). 



Nautilus umhilicatulus, Montagu, 180.3-8, TB. p. 101 ; Suppl. p. 78, pi. .xviii, fig. 1. 

 Nonionina umbilicatula, Heron-Allen and Earland, 1914, etc., FKA. 1915, p. 730. 



Stations 2, 3, 6-12, 16, 18, 19, 22, 23, 29, 49, 50 (-1-T. d. F., D.). 



Generally distributed ; exceptionally good at Stations 6, 7, and 16. At 

 Station 18 the examples are very thick, approaching A^. pompilioides. Fossils at 

 Stations 3 and 6. 



[Arenaceous isomorph, Haplopliragmiuni canariense (d'Orb.).] 



614. Nonionina pompilioides (Fichtel and Moll). 



Nautilus ijomjnlioidcs, Fichtel and Moll, 1798, TM, p. 31, pi. ii, figs. a-c. 

 Nonionina „ Cu.shman, 1910, etc., FNP. 1914, p. 25, pi. xvii, fig. 2. 



Stations 6, 7, 16, 17, 20, 23. 



Good specimens at all the Stations. Its occurrence in such shallow water 

 at Station 6, where excellent recent examples were found, is noteworthy, this 

 being essentially a deep-water form. 



[Arenaceous isomorph, Haplophragmium scihdum, Brady.] 



615. Nonionina boueana, d'Orbigny. 



Nonionina boueana. d'Orbigny, 1846, FFV. p. 108, pi. v, figs. 11, 12. 



Heron- Allen and Earland, 1914, etc., FK.V. 1915, p. 731. 



Stations 2-8, 11 (-hR. d. J.). 



Confined to the N.Z. area ; most abundant at Station 6. Rare and small 

 at Stations 7, 8, and 11. A.t Stations 5 and 6 there is a considerable range of 

 variation, including inaequilateral individuals comparable with var. janiformis, 

 Rupert Jones (J. P. & B. 1866, etc., MFC. 1897, p. 344, Text-fig. 28 a-c), but
