PROCEEDINGS OF THE SOCIETY. 
693 
mcgafrustules in tlic latter diatom growing as in the preceding cases of 
JEpithemia. 
The writer believed this to he the first recorded case of the mode of 
formation of the megafrustule in the genus Amphora ( x 312). 
Nos. 20 and 21 are believed to be the first recorded cases of the for- 
mrtion of megafrustules of Synedra radians. 
The bulb-like appearance in the middle of the megafrustules occurs 
in almost all the specimens examined (x 312). 
No. 22 was that of the formation of two mcgafrustules of Amphipleura 
pellucida , presumably after conjugation, as in the case of Cocconema 
(X 325). 
No. 23 is curious as being a case of the formation of a megafrustule 
of Nitzschia , photographed after the gathering, in which it was found, 
had been boiled in nitric acid (x 325). 
The Secretary said that there was another paper on the Agenda, 
being Fart III. of Mr. F. W. Millett’s ‘Report on the Recent Forami- 
nifera of the Malay Archipelago.’ This paper, although one of consider- 
able value, was so highly technical that it was £>roposed, as in the case of 
Parts I. and II., to take it as read. It would of course appear in extenso 
in the Journal. 
On the motion of the President the thanks of the Society were 
unanimously voted to Mr. Coombe for his paper, and the exhibition of 
slides in connection with it ; and also to Mr. Millott for his further 
communication.
