270. Cristellaria acutauricularis (Fichtel and Moll). 



NaiiUliis acutauricularis, Fichtel and Moll, 1798, TM, p. 102, pi. xviii, figs. g-i. 



Cristellaria acutauricularis, Brady, 1884, FC, p. 543, pi. cxiv, fig. 17. 



Cristellaria acutauricularis, Cushman, 1910, etc., FNP, 1913, p. 69, pi. xxxv, fig. 2. 



One station: WS 225. 



A single typical individual. 



271. Cristellaria hauerina, d'Orbigny. 



Cristellaria hauerina, d'Orbigny, 1846, FFV, p. 84, pi. iii, figs. 24, 25. 



Cristellaria hauerina, Reuss, 1866, FABS, p. 140, pi. iii, figs. 2-4; 1870, FSP, p. 481 ; S, 1870, 



FSP, p. 47, pi. xiv, figs. 27-30; pi. XV, figs. 1-12. 



Cristellaria hauerina, Heron-Allen and Earland, 1915, FSC, p. 47, pi. viii, figs. 2-4. 



One station: WS 88. 



A number of very variable specimens which are nearer to von Schlicht's figures than 

 to d'Orbigny 's original illustration, but the species seems to be extraordinarily variable, 

 hardly any of the Falkland Islands specimens being identical. The Type is missing in 

 Paris so we have not been able to single out any particular variation as fundamental. 



272. Cristellaria obtusata, Reuss. 



Cristellaria obtusata, Reuss, 1870, FSP, p. 479; S. 1870, FSP, pi. xi, figs. 16-18. 

 Cristellaria obtusata, Brady, 1884, FC, p. 536, pi. Ixvi, fig. 17. 



One station: WS 88. 



One typical specimen. 



273. Cristellaria lata (Cornuel). 



Marginulina lata, Cornuel, 1848, NFM, p. 252, pl. i, figs. 34-7. 

 Cristellaria lata, Brady, 1884, FC, p. 539, pl. Ixvii, fig. 18 a, b. 

 Cristellaria lata, Burbach, 1886, etc., FLS, p. 500, pl. x, figs. lo-ii. 



Two stations: 388; WS 88. 



Some good specimens at each station, but the species is, zoologically, merely a broad 

 variety of C. crepidida, which species, at this station, runs imperceptibly into it. 



274. Cristellaria gibba, d'Orbigny. 



Cristellaria gibba, d'Orbigny, 1839, FC, p. 40, pl. vii, figs. 20, 21. 

 Cristellaria gibba, Brady, 1884, FC, p. 546, pl. Ixix, figs. 8, 9. 

 Cristellaria gibba. Chapman, 1914, EDRS, p. 44, pl. v, fig. 8. 



Fifteen stations: WS 71, 76, 80, 83, 84, 86, 87, 88, 89, 91, 217, 221, 225, 408, 433. 



The finest specimens at WS 86 and 408, others almost equally good at WS 84, 87 and 

 88. At the remaining stations the specimens are as a rule very small. At WS 86, the 

 specimens are large and more compressed than usual, forming a link between typical 

 C gibba and C. crepidida. The Type is missing.
