A striking feature of the foramini feral fauna of the Arabian 

 Sea is the presence therein of a number of forms which have 

 already been described b_y Dr. Conrad Schwager^ from marine 

 clny-beds, of late Pliocene age, on the northern coast of Kar 

 Kicobar ^ 



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 hst of recent 

 Foraminifera, but which have formerly been recorded as fossils : 

 these are: — Te.vtidaria lytJiostrotum [iich\yager), CassiduUna mur- 

 rhina (Schwager), Lagena capillosa (Schwager), Nodosaria (Ben- 

 talina) adolphina (d'Orb.), Nodosaria ovulata, Sherb. & Chap., 

 Nodosaria (D.) acicula. Lam., Polymorphina fusiformis (Ecimer), 

 and Calcarina nicoharensis, 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" 34' K, long. 87^ 59' E.) is 

 given by Dr. John Murray in the ' Scottish Geographical ]\laga- 

 zine' for August 1889. The material examined was a blue mud, 

 obtained at a depth of 1300 fathoms. x\mongst 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
