Eep. vol. ix. p. 501, pi. lxii. figs. 23, 24. Found in Sample No. 1, rare; No. 2, very rare. 169. NODOSAEIA (DENTALINA) INFLEXA, Eeuss. Nodosaria (Dentalina) inflexa, Brady, 1884, Chall. Eep. vol. ix. p. 498, pi. lxii. fig. 9. Found in Sample No. 5, rare. 170. NODOSAEIA OVULATA, Sherborn & Chapman. Nodosaria ovulata, Sherborn and Chapman, 1886, Journ. Eoy. Micr. Soc. ser. 2, vol. vi. p. 747, pi. xiv. fig. 27. This species was described for the first time from the London Clay of Piccadilly. The specimens from the Arabian Sea agree very closely with the fossil ones. Found in Sample No. 5, rare. 171. NODOSARIA (DENTALINA) SOLUTA, Eeuss. Nodosaria (Dentalina) soluta, Brady, 1884, Chall. Eep. vol. ix. p. 503, pi. lxii. figs. 13-16. Found in Sample No. 4, very rare; No. 6, rare. 172. NODOSARIA (DENTALINA) SOLUTA, var. SUB ACULEATA, nov. (Plate I. fig. 6.) " Faintly striate specimen."-See Brady, 1884, Chall. Eep. vol. ix. p. 503, pi. lxiv. fig. 28. This variety differs from the type form in having the basal half of each chamber ornamented with numerous fine prickles, which fade off into faint stria3 towards the middle of the bulb. The general contour of the test of this variety agrees with that of the type ; and the examples found are well-developed in point of size. Length about i inch (5 mm.). Dr. Brady has figured a specimen which is undoubtedly referable to the above variety, though it is not so strongly ornamented as are the specimens from the Arabian Sea. For this reason I venture to separate them from the smooth typical forms by a varietal name. Found in Sample No. 1, rare; No. 3, very rare; No. 4, rare ; No. 5, very rare. 173. NODOSARIA (DENTALINA) ACICULA (Lamarck). Orihocera acicula, Lamarck, 1822, Hist. Anim. sans Vert. vol. vii. p. 594, no. 5. Dentalina acicula, Sherborn and Chapman, 1886, Journ. Eoy. Micr. Soc. ser. 2, vol. vi. p. 751, woodcut fig. 154. This species is well known as a Tertiary fossil, Lamarck having found it in the Middle Eocene of the Paris Basin; and it is also |
