The specimen from the Gristhorpe plant-bed, which is 

 figured by Lindley and Hutton as Thuites expansus, is, 

 I have no doubt, specifically identical with the plant 

 which these authors represent in plates clxxxviii. and 

 ccxix. as Brachyphyllum niamillare. The specimen has a 

 length of 9'5 cm., and represents an imperfectly preser\'ed 

 twig, bearing short lateral branches clothed with spirally 

 disposed and fleshy broadly triangular scale-leaves, closely 

 adpressed to the axis. Each leaf terminates in a sharp 

 point, and is traversed on the ab-axial surface by a fairly 

 prominent median ridge.
