of the Bracklesham beds with the living species found in Australian 

 shore-sands. Recent specimens of Bolivina Durrandii (Millett) and Pid- 

 vinulina vermiculata (Brady) were shown, the only other known records 

 being, as regards the former, from the Malay Archipelago, and as regards 

 the latter, from tropical and sub-tropical seas. In addition to these, 

 M Molina suborbicularis and rotunda ; Textularia inconspicua x&v.jugosa ; 

 I'viijerina aspenda • and Sagrina dimorpha were recorded as new to 

 Britain. Schlumberger's hitherto unique genus and species, Linderina 

 brugesii, was recorded from the Eocene 'days of Selsey. Also the first 

 fossil records of Bulimina subteres and Discorbina polystomelloides. The 

 new species recorded were Pulvinulina haliotidea (H.-A. and E.) and 

 Nonionina quadrilocidata (H.-A. and E.). Specimens of these were 

 exhibited under Microscopes on the table. 



On the conclusion of the lecture and demonstration the President 

 said that it was hardly a subject that lent itself to discussion, and as no 

 remarks were forthcoming on this most interesting paper, it only remained 

 for him to congratulate Mr. Heron- Allen and Mr. Earland on the extent 

 and importance and beauty of their work. 



He gathered that they were giving up Selsey Bill for the North Sea, 

 and he hoped that they would there be equally successful in the result 

 of their researches. He was sure that all would wish to return a very 

 hearty vote of thanks for the interesting paper and for the beautiful 

 specimens exhibited and lantern slides shown, which had helped to render 

 the lecture so clear to those who, like himself, knew but little of its par- 

 ticular subject. 



The vote of thanks was carried with acclamation. 



Mr. Heron-Allen thanked the Fellows of the Society for the way in 

 which they had listened to him, and hoped that in years to come, when 

 they had to some extent completed the North Sea investigations, the 

 same kindly attention would be accorded them. 



Owing to the late hour the paper by Mr. E. M. Nelson on " Some 

 New Objectives and Eye-pieces, by R. Winkel, of Gottingen," was post- 

 poned till the next Meeting. 



The next Meeting was announced for March 15, when Dr. Ralph 

 Vincent would give a demonstration on the " Morphology of the 

 Organisms concerned in the Production of Acute Intestinal Toxasniia in 

 Infants," and Mr. F. W. Watson-Baker would read a paper, entitled 

 " Anomalies in Objective Screw Threads." 



The following- Instruments, Objects, etc., were exhibited :— 



Messrs. Heron-Allen and Earland exhibited a number of rare and in- 

 teresting species of Foraminifera from the Shore-sands of Selsey Bill, 

 Sussex. 



Mr. Lees Curties : — A New Dark-ground Illuminator, made for Mr. 

 Nelson.
