A striking feature of the foraminiferal fauna of the Arabian Sea is the presence therein of a number of forms which have already been described by Dr. Conrad Schwagerl from marine clny-beds, of late Pliocene age, on the northern coast of Kar Nicobar 2 Although many of the species recorded from those fossil beds were subsequently found by Dr. Brady in the 'Challenger' soundings, yet there still remained at least five well-defined forms recorded by Dr. Schwager from the above-mentioned Pliocene beds, and these are noted here for the first time as recent Foraminifera. There are altogether eight species new to the list of recent Foraminifera, but which have formerly been recorded as fossils: these are:-Textularia lythostrotum (Schwager), Gassidulina mur-rhina (Schwager), Lagena capillosa (Schwager), Nodosaria (Den-tedina) adolphina (d'Orb.), Nodosaria ovulata, Sherb. & Chap., Nodosaria (D.) acicula, Lam., Polymorphina fusiformis (Romer), and Calcarina nicobarensis, Schwager. Besides these there are two new species and three new varieties. A list of Foraminifera obtained from the Bay of Bengal by H.M.S. 'Investigator' (from lat. 17° 3 4 N., long. 87° 59'E.) is given by Dr. John Murray in the ' Scottish Geographical Magazine ' for August 1889. The material examined was a blue mud, obtained at a depth of 1300 fathoms. Amongst the thirty-seven species therein enumerated there are, however, no Tertiary species such as were obtained from the Arabian-Sea deposits. In concluding these preliminary remarks it only remains for 1 "Fossile Foraminiferen von Kar-Nicobar." Novara-Exped oeol Theil vol. ii. 1866, p. 187. 4to, Wien. 2 F. von Hochstetter, op. cit. p. 88. |
