NOTES AND EXHIBITS. 393 



It had been placed in Jordan's genus Germo because of the large 

 pectoral fins, but the validity of that genus was open to doubt. 

 Tlie species was closely allied to Temminck and Schlegel's 

 Thynnus macropterus. 



Mr. T. G. Taylor exhibited photographs which filled a gap 

 between ordinary camera photos {\) and microphotos (Y*), 

 obtained by the use of an Express Enlarger, giving magnifica- 

 tions direct from the micro-section of 2 up to 10 diameters. This 

 apparatus is ordinarily used for bromide enlargements or lantern 

 slides, but is very suitable for enlarging large coral calices, which 

 are not wholly visible in the microscope field. Imperial Special 

 Rapid Plates were used; blue sky, 2-10 seconds exposure. 



Mr. Froggatt exhibited a sample of the seed of some forage 

 plants, recently imported from France, which had mixed with 

 it numbers of dried land snails {Helicella candidula Studen). 



Dr. Woolnough showed a number of photographs taken in 

 Fiji, in illustration of his paper. A series of lantern slides will 

 be shown at a future Meeting when the lantern is ae^ain available.
