PLATE XLVII. 



Spiropteris (?) 



SCHIMPEE. 



A very puzzling specimen. Probably another form of 

 circinate vernation, but the impression is too imperfect 

 as to details to enable anything but the general aspect of 

 the plant being seen. Hutton himself could assign it no 

 name, and sent one side of the fossil to De. Lindley, 

 together with the drawing, "that you may have a better 

 guess what this is." Lindley, however, returned the 

 drawing marked with a query. 



The specimen is an impression " in shale from Jarrow 

 Colliery." 



The drawing, by Prior, is of the natural size, and so 

 is the Plate.
