XXXIII] PELOTJRDEA 281 



of p. vogesiaca, but there is no evidence as to their manner of 

 attachment; they are 30 — 40cm. long and from 1-5 to 2 cm. 

 broad. 



Pelourdea megaphylla (Phillips). 



This species was first described by Philhps^ from the Middle 

 Jurassic Stonesfield Slate and afterwards referred to Zamites^: 

 the leaves bear a striking resemblance to foliage of the type 

 Cordaites borassifoUus ; the lamina is 30 cm. long and attains 

 a breadth of 3 cm., the apex is acuminate and shghtly contracted 

 towards the broad concave base. My former comparison of these 

 Stonesfield leaves with the long pinnae of Ceratozamia mexicana 

 seemed to be supported by Phillips's type-specimen of Palaeozamia 

 longifolia. It may be that the supposed pinnae in PhilUps's 

 type are spirally disposed leaves : if this is the case the specimen 

 may be a fragment of a Podozamites ; its specific identity with 

 the larger detached specimens, though probable, cannot be demon- 

 strated. Some leaves figured by Zigno* from Jurassic rocks of 

 Italy as Yuccites Schim/perianus may be identical with P. mega- 

 phylla. 



Pelourdea mirabilis (Velenovsky ex Corda ms.). 



The generic name Krammera, suggested by Corda, was employed 

 by Velenovsky* for large Cordaites-lihe leaves from the Lower 

 Cretaceous of Bohemia, for casts of cones regarded by him as 

 stems, and for fruit-like bodies. The leaves, previously described 

 as Flahellaria chamaeropifoUa Goepp., Dammara albens Presl, etc., 

 bear a close resemblance to the large broadly hnear leaves of 

 Cordaites ; the lamina reaches a length of 40 cm. and between 

 the veins occur 1 — 4 finer striations. The fossils identified by 

 Velenovsky as stems bearing crowded imbricate scales, which 

 he regarded as the persistent bases of Krammera leaves, are 

 probably cones; they agree very closely in size and shape, also 

 in the form of the scales, with cones of Agathis and some other 

 recent Conifers. As the designation Krammera was instituted 

 primarily for cones and not leaves the name Pelourdea is substi- 

 tuted for it.
