Several impressions of a conifer strongly resembling Pagiophyllum 
Williamsonis were found at the locality ‘‘In the bed of a ravine 
that leads from the Banner mine,” etc. The largest imprint is that 
of astem 8 cm. long. This has portions of several branches and one 
entire branch. The latter is 15 mm. long and bears at its summit an 
elliptical, scaly cone, of the same shape and dimensions as that 
depicted by Lindley arid Hutton on a branch of their Lycopodites Wil- 
Liamsonis on pl. xciii of the second volume of the Fossil Flora of Great 
Britain. This, as Schimper showed, is not a Lycopodites, but a coni- 
fer, of the type he named Pachyphyllum, and for which, owing to the 
preoccupation of the name Pachyphyllum, the appellatian Pagiophyl- 
lum of Heer is now chosen. 
The stems carry one-ribbed, curved, and stiff leaves, in the Oro- 
ville specimens. There is no doubt that they belong to the genus 
Pagiophyllum, and are very near to the English plant.

' Several detached fragments of a broad-leaved Pinus were found at 
the localities ‘‘In the bed of a ravine that leads from the Banner 
mine,” etc., and ‘‘ The old dump at the Banner mine,” etc. They show 
neither their bases nor their tips. They belong to broad, stiff, one- 
nerved Pinus leaves that agree well with Heer’s plant. * Of course no 
positive determination can be made from such imperfect material.
