have been protluced from similar causes. A comparison of 

 tigs, c? and /> almost demands this conclusion. Beyond evi- 

 dence gained from an examination of the surface of the fossil 

 there is none ; but as all the characters exhibited on tlie outer 

 surface of recent Equisetum occur on the fossils, I think I am 

 quite justified in placing the Yorkshire specimens in the 

 genus Equisetum. 



It gives me pleasure to name this species after Mr. Heming- 

 way, to whom 1 am much indebted for many interesting fossil 

 plants from the Yorkshire Coal-field. 



Before concluding these notes, I may add that the liippu- 

 rites (]i(faiitea, L. & II.*, from the Lower Coal-measures, 

 Jarrow Colliery, of which the type is preserved in the Ilutton 

 Collection, and which MM. Kenaurt and Zeiller thought 

 might possibly belong to the genus Equisetum^ is a portion 

 of a stem of Calamitina (probably Calamitina varians, 

 var. insigniSj Weiss), and has no very close alfinity with the 

 genus Equisetum. I have examined the type, and the leaves 

 appear to spring from the node, not as teeth of a sheath, as 

 represented on their plate, but as free and independent 

 organs placed close together f. 



Equisetum Monyij \i. & Z., came from the Upper Coal- 

 measures, whereas Equisetum Hemingwayi originates from 

 the Middle Coal-measures.
