NOTES FOR STUDENTS 
Paleobotanical notes.—ARBER? has done a most useful service in revising 
the seed-impressions of the British Coal Measures, and putting them into more 
definite categories. The most recent list, that of KmpsTon in 1894, included 
5 genera with 19 species. ARBER’S revision contains 14 genera with 37 species. 
These detached seed-impressions belong to both Cycadofilicales and Cor- 
daitales, whose seeds cannot be distinguished. Of the 14 genera recognized 
9 are new (Platyspermum, Cornucarpus, Samarospermum, Microspermum, 
M. egalospermum, Radios ermum, N eurospermum, Schizospermum, Pterosper-

Showing that the sclerenchyma of the micropylar beak is preserved as far as 
its extreme apex, and also that the nucellus was free from the integument 
almost to the base of the seed.
