This fonn is very abundant and excellently well preserved in the Collier collections, and 

 Heer also speaks of it as being an abundant form in the sandstones at Cape Boheman, Spitz- 

 bergen. At fii'st Heer described it with full specific rank, but later he inclined to regard it as 

 merely a variety of the omnipresent P. lanceolatus, and this is the view taken by Nathoi-st, 

 who restudied Heer's specimens together with much additional material. Nathorst states that 

 three forms of P. lanceolatus are jjresent at Cape Boheman — P. lanceolatus genuinus, P. I. elcli- 

 ^valdi, and P. I. ovalis. It is quite possible that a large series might show that these forms so 

 intergrade as to make it unsatisfactory to attempt to draw any sharp lines between them, but 

 in the present collection they appear very distinct. For stratigraphic purposes the variety 

 eichwaldi is certainly well marked, a fact which is of interest m the j^resent comiection as tend- 

 ing to connect the Cape Lisburne region with other undoubted Jurassic localities.

This species, described originally from the Jurassic of Wurttemberg, was found by Moller 

 at Bornholm in beds regarded as either Rhsetic or Liassic. Whether Moller has been correct 

 in determuimg the Bornholm plants as identical with Pagiophyllum kurrii need not be discussed 

 at this time, but it is certain that the specimens so figured and named by him are not to be 

 distinguished from the Cape Lisburne example here figured. For instance, MoUer's Plate V, 

 figure 12, shows a short branchlet with broad, rather obtuse leaves that is certauily the same 

 as the specimen from Cape Lisburne. 



On the same piece of matrLx and lying very close to the branchlet from the CoUier collection 

 is the apical portion of another branchlet which maj' or may not represent a very unmature 

 cone. It is not well preserved and hence can not be matle out with certainty. Just below the 

 "cone" are two or three leaves of the same size and appearance as those on the adjacent 

 branchlet; below these the leaves l)ccome crowded and a|)])arently narrower and shorter. 

 It is. on the whole. j)robable that this is merely a growing tip in which the leaves are not fully 

 deA'eloped.
