214 MESSES. E. HEKON-ALLEN AND A. EAELAND ON THE 



Stns. the round-edged form occurs alone, the square-edged only at Stns. 7, 11, and 23. 

 Both forms occur together at Stns. 1, 18, and 22. 



39. Miliolina ferUSSacii (d'Orhigny). (Plate 40. figs. 1-9.) 

 Quinqueloculina ferussacii, d'Orbigny, 1826, TMC. p. 301. No. 18, Modele No. 32. 

 Miliolina ferussacii, Brady, 1884, EC. p. 175, pi. cxiii. fig. 17.

Scantily represented, hut at some Stns. reaching quite exceptional size and develop- 

 ment. D'Orbigny's " Modele " is not very satisfactory from the point of view of recent 

 records, as it exhihits an aperture situated on a produced neck, and with few and very 

 strongly marked costse. Recent specimens, however, have, as a rule, but a very slightly 

 produced neck and numerous but not prominent costal ridges. The species is abundant 

 in many British dredgings, and round the Shetland shores especially attains a larger size 

 than any other Miliolid. The first British record of this species was by Williamson 

 under the name Miliolina bicornis, var. angulata (W. 1858, RFGB. p. 88, pi. vii. 

 fig. 196). 



40. Miliolina pulchella (d'Orbigny).

4 Stations. 



Very rare, but large and excellent individuals at Stn. 1. 



41. Miliolina brongniartii (d'Orbigny). 



Triloculina brongniartii, d'Orbigny, 1826, TMC. p. 300, No. 23. 



Quinqueloculina brongniartii, syn. of M. bicornis, Brady, 1884, FC. p. 172, pi. vi. fig. 9. 



Miliolina brongniartii, Heron-Allen & Earland, 1913, CI. p. 33. 



21 Stations. 



Much more widely distributed in these dredgings than its ally M. bicornis. Common 

 at many Stns., the best at Stn. 15. 



42. Miliolina bicornis (Walker & Jacob). 



Serpula bicornis, Walker & Jacob, 1798, AEM. p. 633, pi. xiv. fig. 2. 

 Miliolina bicornis, Brady, 1884, FC. p. 171, pi. vi. figs. 11, 12. 



12 Stations. 



Widely distributed, but specimens are rare and seldom strongly developed. The best 

 at Stns. 18 and 23. Adelosine examples at Stns. 1, 10, 18, 20, and 23.
