wrinkling of their substance. A comparison may be suggested 



with the broadly winged seeds of the recent Welwitsehia,^ an 



isolated genus of tropical Africa, and the only representative of 



the Welwitschoideffi, a subdivision of the Gnetales. The specimen 



is, however, too obscure to determine, and can only be spoken of as 



possibly a winged Gymnospermous seed referable either to the 



Coniferales or to the Gnetales. A seed of similar form has been 



figured by Nathorst from the Rhsetic of Scania as Samaropsis 



Zignoana, Nath.^

[Ref erred by Buckman to the Angiosperms.] 



The list of plants " from the Lower Lias " given by Mr. Buckman 

 in his paper of 1850^ incUides three specimens referred with 

 some doubt to the XJmbelliferae, Ericaceae, and to the genus 

 Mippurites. It is important to examine with care any possible 

 indications of Angiospermous plants in pre-Cretaceous rocks, and 

 to draw attention to recorded instances of supposed Flowering 

 plants that are botanically valueless. There need be no hesitation 

 in dismissing Buckman's fossils as afiording no evidence justifying 

 their reference to the Flowering plants. The following specimens 

 in the Museum collection are too obscure and fragmentary to 

 determine, and, while asserting that they are not the remains of 

 Dicotyledons or Monocotyledons, I am unable to express an opinion 

 as to their nature.
