lie, some on one side, some on the other, of the ideal Crypto- 

 g-amic-Phanerog-amic boundary. The demonstration that some- 

 thing- like a debatable land once lay on this frontier, now so well 

 delimited, is perhaps the greatest contribution which Palseo- 

 botany has yet made to the Theory of Descent.' As is the 

 general case with Dr. Scott's papers, this is well illustrated, and 

 we are permitted by the society to reproduce herewith one of the 

 figures. It is a photograph of Sphenopteris Honinghausi^ the 

 foliage of Lyginodendron, a fragment of the highly compound 

 frond showing spiny rachis with pinnse, pinnules, and small 

 incurved leaflets. 



In the October ' Geological Magazine ' the Editor, Dr. 

 Henry Woodward, F.R.S., describes some Crustaceans and two 

 Myriopods from the Lower Coal-Measures near Colne, Lanca- 

 shire. ' All the specimens are enclosed in small elliptical nodules 



mitted to figure herewith is from Mr. Peter Whalley's collection. 

 It is from the soap-stone bed at Carre Heys, Colne. In the 

 nodule is a coiled up myriopod having indications of a head, and 

 about thirty equal-sized segments, each composed of a saddle- 

 shaped plate rounded at its lower edge. Dr. Woodward also 

 figures and describes other interesting forms from this productive 

 zone in the coal-measures. His notes are prefaced by a descrip- 

 tion of the Geological horizon, etc., of the soap-stone bed, by
