269.— Carpolithes data, L. et H. Type specimen, F. F., pi. 87, f. 2. 

 Pericarp of a fruit of an elongated elliptical shape, about the 

 size of a date, containing impression of a nucleus or kernel 

 (Trigonocarpon), the size of a small nut ; the surface divided 

 into three distinct compartments agreeing with the three- 

 fold division of the pericarp. The immature kernel has an 

 elongated, three-sided tapering spike ascending to the top of 

 the pericarp. This specimen appears to represent one-third of 

 the pericarp, having the impression of one side of the nut and 

 spike. Hutton's label is " Carpolites, Jarrow, Bm." 

 Loc. — Shale above the Bensham Seam, Jarrow. {H. C. 585). 



270. L. et H. Type specimen, F. F., pi. 87, f. 3. 



About the same size as f. 2, but only half the base of the 

 pericarp is preserved, and shews the circular attachment to 

 a stem or stalk. The kernel is also present in this, and shews 

 on its surface one of the three strong dividing ridges of the 

 kernel and the spike, carbonized, and traces of the flue vas- 

 cular lining of the interior of the pericarp. Hutton's label, 

 "Carpolites, Jarrow, Bm." 

 Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 587). 



271. About the same size as the preceding, and shews the fine 



vascular lining of the pericarp and the position of the kernel, 

 which appears not to have been mature, or so much so as the
