67. — Asterophyllites Lebour, 111. Foss. Pits., pi. 9. Type. 



Long, finely-striated stem, with very long internodes, and with 

 two or three joints of the fertile spike at the top. Compare 

 this with the lower part of specimen figured in F. F., pi. 180. 

 Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 607). 



68. — Aster, tuberculata. 



This specimen 

 shews four joints 

 or nodes of the 

 lower or basal part 

 of the fertile spike 

 and an inch of the 

 stem with a joint 

 near the lower part. 

 The stem is about 

 one-sixth of an 

 inch in width at 

 theupper joint, and 

 rapidly increases, 

 till at the first joint 

 of the spike it is 

 half an inch. There 

 is a transverse de- 

 pression above each 

 joint, and a whorl 

 of fine tubercles, the points of attachment of leaves or bracts, 

 round each node of the spike. Where the top of the spike is 

 broken off, the upper joint shews part of a whorl of seven or 

 eight fine leaves, one-sixth of an inch in length, each leaf 

 with distinct mid-rib. The whole surface finely striated 

 longitudinally. (Woodcut No. 1). 

 Loc. — Shale above the Low Main Seam, Felling. (H.C. 616). 



69. Two joints of a slender stem, with portion of cone similar 



to A. tuberculata at the top. It is perhaps the counterpart 

 of 67. 



Loc— Shale above the Low-Main Seam, Felling. (H. C. 607). 

 (43A). 



70. Lebour, 111. Foss. Pits., pi. 5. Type. 



A portion or counterpart of the following specimen. Several 

 spikes are attached to a fertile stem ; altogether remains of
