433. Cristellaria gihba, d'Orbigny. 



Cristellaria gihha, d'Orbigny, 1839, FC. p. 10, pi. vii, figs. 20, 21. 



Cu.shmaii. 1910, etc., FNP. 1913, p. 69, pi. xxxv, fig. 1. 

 Stations 1-3, 6-8, 16, 19, 20. 



Excepting at Station 6, where it is frequent and tvpieal and large, tlie specimens 

 are not noteworthy. 



434. Cristellaria articulata (Reuss). 



Rohulina articulata, Eeu.ss, 186.3-1, KTF. p. .53, pi. v, fig. 62 ; pi. vi, fig. G3. 

 GristcUana ,. Cushman, 1910, etc., FNP. 1913, p. 65, pi. xxxi, fig. 1. 



Stations 1, 2, 3, 6, 27. 



Confined to the N.Z. area, except for one compressed individual at Station 27. 

 In the N.Z. area it is very large and typical, and also fossil and typical at Station 6. 

 At Stations 1 and 3 not conspicuous. Station 2 is marked by a proftision of 

 wild-growing specimens in every stage of development, from a single fistulose 

 chamber on a normal shell, to larger and more complex and protean examples 

 than those figured by Brady. Incidentally these confirm Brady's judgment in 

 attributing his specimens to Cristellaria and disprove Schlumberger's contention 

 that these wild growths are an Amphicoryne related to his A. parasitica (S., 1892, 

 FAM. p. 197, pi. viii, figs. 10-12). Whatever Schlumberger's form may be (and 

 we suspect that it is identical with Brady's) there is no doubt that Brady's 

 specimens and our own are developments of C. articulata. 



435. Cristellaria rotulata (Lamarck). 



Lenticulites rotulata, Lamarck, 1804, AM. p. 188, no. 3 ; 1816, TEM. pi. 466, fig. 5. 

 Cristellaria „ Heron-Allen and Earland, 1914, etc., FKA. 1915, p. 671. 



Stations 1-7, 10-12, 18, 36. 



Generally distributed down to Station 18, and a broken specimen at Station 36. 

 It often attains considerable size at the N.Z. Stations, especially at Stations 2 and 6. 

 Fossils at Stations 2, 3 and 6. 



436. Cristellaria vortex (Fichtel and Moll).

Stations 1, 2, 3, 6. 



Confined to the N.Z. area. Very fine and typical at Station 6. 



437. Cristellaria orbicularis (d'Orbigny). 



Rohulina orbicularis, d'Orbigny, 1826, TMC. p. 288, no. 2, pi. xv, figs. 8, 9. 

 Cristellaria „ Cushman, 1910, etc., FNP. 1913, p. 67, pi. xxxvi, figs. 4, 5. 



Stations 1, 2, 6. 



Confined to the N.Z. area and rare, except at Station 6, where the specimens are 

 very good.
