BracTiyphyllum, ;md as indicating the very close resemblance 

 between the Yorkshire plant and Clieirolepis Muensteri, Schonk. 



The vegetative shoots branch at a more acute angle than in 

 Brachyplxyllum. The leaves arc crowded, spirally disposed, fairly 

 stout, and falcate in form. 



The fragments of this species resemble in habit Sequoia gigantea, 

 Lindl. & Gord., and maybe compai'ed also with Arauoa/ria Balamm, 

 Brongn. & Gris., and Bacrydium Franhlinii, Hook., but the material 

 is too meagre and ill preserved to admit of a full diagnosis or of 

 a satisfactory comparison with recent Conifers. 



40,570. Several fragments similar to the Scarborough example 

 (Kg. 53a) ; imperfect and fragmentary. 



Genus BRACHYPHYLL.UM, Brong-niart. 



[Tableau, p. 69, 1849.] 



The genus Bracliyphyllwni,^ like many other fossil Conifers, 

 ■cannot be safely assigned to any definite position among recent 

 genera. The habit of the branches and the form of the leaves 

 iavouj a comparison with some species of the Tasmanian genus 

 Arthrotaxis ; but we are not in a position to speak with confidence 

 as to affinities of this common Mesozoio genus.
