The type of Zepidostrohus pinaster, L. and H. (vol. iii., pi. 

 cxcviii.), in the " Hutton Collection " is also LepidopMoios 

 carinatus, Weiss. The leaf-scars are well preserved on this 

 example, and the central and two lateral cicatricules are 

 well seen. The supposed bracts that spring from the 

 Lepidostrohus pinaster (which is drawn upside down, as 

 shown by more perfect specimens) are not organic, but 

 splinters in the matrix. The original is quite unlike a cone, 

 and it is difficult to conceive how such a fissure of the fossil 

 could have been produced.^ 



Zeiller,^ from the synonymy under the head of Lepido- 

 phloios laricinus, appears to unite LepidopJiloios carinatus 

 with Lepidophloios laricinns, Sternb., but I have evidence 

 which leads me to think that these plants are specifically 

 distinct. I hope presently to publish figures and descrip- 

 tions of the examples upon which I have formed this opinion. 

 The plant under discussion must now be called Lepido- 

 phloios ACEROSUS, L. and H. sp.
