Some specimens in Dr Kidston's collection from the Lower Coal Measures of Midlothian, which were associated with Eremopteris fronds, are preserved as mummified cuticular membranes and on microscopical examination they show clearly the presence of a pollen-chamber. The seeds are of the Sama- ropsis type. The drawings reproduced in fig. 444 were made for me by Dr Kidston from two specimens, in his collection, 1 Howse (88) p.
