I^ote on Nummulina planulata, Lamarck, sp., var. Prestwichiana, 

 Jones. By T. Rupeet Jones, F.G.S. 



This little Nummulite is discoidal, smooth, and flat, rarely in any 

 degree biconvex, even in the young state, unless the outer whorl has 

 been flattened by pressure ; about ^th inch in diameter, and J^th 

 in thickness. The gently sigmoid and semitranslucent edges of the 

 septa appear at the surface, and but seldom rise above it (except 

 when the specimens are mechanically compressed, which is a common 

 condition). The whorls (three in large specimens) are all visible in 

 empty shells made transparent by water or Canada-balsam ; they 

 are proportionally wide for Nummidina (the outer whorl making half 

 the width of the disk). The chambers are about half as long as 

 wide, neatly curved, but subject to irregularity of growth. The 

 lateral portions of the chambers, though very shallow, are continued 

 over the surface towards the centre on each face, and are rather 

 straighter in old specimens than in the young.
